What to do: Once chemotherapy is stopped, your hair will grow back although often it will come back with a different texture (perhaps curly when before it was straight) or a different color. Researchers are working on more targeted drugs to treat cancer, ones that would bypass this and other side effects. In the meantime, Here's How to Deal With Thinning Hair During Chemo.
My hair began to thin when I was 28 years old. Now I am 44 and the top of my head is bald. Recently, I considered using medicine to treat my hair loss and see if any hair would regrow. After reading the literature and talking to my doctor, I decided not to take medicine because it is unlikely to make a huge difference in my hair—and I don't want to take medicine forever!
Although many medications list "hair loss" among their potential side effects, most drugs are not likely to induce hair loss. On the other hand, cancer treatment (for example, chemotherapy or radiation therapy) and immunosuppressive medications commonly produce hair loss. Complete hair loss after chemotherapy usually regrows after six to 12 months.
The scalp contains a natural oil called sebum, which helps keep the skin lubricated. Sebum is produced by the sebaceous glands. Sometimes these glands work overtime and produce too much oil, leading to a greasy scalp. Greasy hair can look dull, limp, and lifeless, and it may be more difficult to manage. To treat greasy hair, try washing with a gentle shampoo that is specially formulated to control sebum.
Periods of prolonged or severe illness can affect the hair. “As with extreme stress and extreme diets, this also comes down to the body preserving its energy balance and shutting down non-essential functions in order to battle the illness more effectively,” Berg says. “In fact, physicians have used an inspection of the fingernails and hair quality as part of standard examinations of overall health for many years. Changes in these features provide some clues about the length and severity of illness.” Other diseases, such as diabetes and lupus, can also cause hair loss. Check out these other things your hair can reveal about your health.
Dealing with hair loss is one of the most painful things in the world. It is hard to just sit by and watch as your hair withers away. So – don’t! With all the new technologies and age-old natural remedies, dealing with hair fall has become a lot easier than it used to be. With this handy guide, you too can battle hair loss and come out victorious. Do you know any other ways on how to stop hair loss naturally? Share it with us by leaving a comment below.
Hair loss doesn't happen fast, our strands grow in cycles, which means it can take up to 3 months for hair to fall out after a trigger has caused it. "If you notice excessive daily hair shedding for longer than 3 months, see a trichologist or your GP, there could be an underlying factor that needs to be addressed", Anabel advises. "Very importantly, try not to panic. Telogen effluvium (excessive shedding) is almost always self-eliminating and hair will start to grow back as usual once any internal imbalance is put right".
As I mentioned before, the causes of hair fall are innumerable, and so it becomes crucial to get to the root of the problem. The best way to go about dealing with the problem would be to get the correct diagnosis to begin with. This can be made simpler by finding the areas where thinning is most prominent and also monitoring how much hair you are losing whenever you comb or shampoo. Consult a physician to find out whether you have any underlying medical issues causing the hair fall.
Involutional alopecia. This one is less of a medical condition (it's not caused by a disease or genetics) and is more concerned with the hair growth cycle. Also called telogen effluvium, this condition is marked by a long dormant phase of telogen than growth or anagen. This type of hair loss is the second most common next to pattern baldness but is also the most unpredictable and difficult to pinpoint its cause. Studies have shown that the dormancy phase in the hair growth cycle is related to a range of factors, including hormonal imbalances, pregnancy in women, stress, diet, etc. 

Losing your hair can be distressing, but if it is caused by thyroid disease it is most likely reversible. In the meantime, try to stave off further hair loss by treating your hair gently. Avoid brushing it excessively, using harsh coloring products, and hairstyles that pull on the hair (such as a tight bun). If you feel self-conscious about having thin hair or bald patches, consider wearing a scarf or wig while your hair grows back.
2. Volumizing shampoos and treatments. Typically, these work by depositing ingredients, like wheat protein and keratin, that adhere to the hair shaft to a) thicken it and b) create spaces between hairs so you look like you have more of it. Try Kiehl’s Rice & Wheat Volumizing Shampoo ($18) with hydrolyzed wheat protein; Rogers likes Redken Cerafill Defy Shampoo and Conditioner ($20 each) with ceramides that bulk up hair.
Anagen is the growth phase. This lasts for about 3 - 5 years, where you can observe your hair growing half an inch every month. Full-length hair from this phase is about 18 - 30 inches long. Studies show that this phase may also be affected by other factors. Asian hair, for example, has been found to have a longer anagen phase. Weather is also a factor; hair growth can be faster in summer than in winter.
What’s got less evidence supporting its efficacy are the hair-growth shampoos that claim to block DHT (like those sold by Hims in their Rx Hair Kit). Rieder is skeptical that you’re going to see any tangible benefits by rubbing DHT blockers into your scalp. “I find it very difficult to believe that something that’s applied to the scalp and rinsed off is going to have any appreciable effect.” All four doctors also shut down any suggestions that hair-growth supplements or vitamins, like biotin, could help promote hair growth or stop hair loss — though a couple hypothesized that vitamins or supplements could lead to hair regrowth if your hair loss was a result of a nutritional deficiency. But otherwise, if you’re dealing with regular old male-pattern baldness, “There is no such thing as a ‘hair vitamin,’” says McMichael.

Finasteride inhibits an enzyme that converts testosterone to DHT, or dihydrotestosterone, the hormone that causes hair loss in men, and unlike minoxidil, this drug can actually help hair grow back, as well as prevent further loss. All you have to do is take one pill a day, and according to Dr. Evan Rieder, dermatologist in the Ronald O. Perelman Department of Dermatology at NYU Langone Health, two-thirds of men taking this treatment will see improvements in hair density over time.
While the drug is generally safe for use, some possible side effects are mild irritation of the scalp, dryness and growth of hair on some parts of the body, especially the sides of the face and hands. In some cases, you might observe some increased hair loss around the first few days of use. If the hair fall continues after two weeks upon application of minoxidil, stop the treatment first and see a doctor.
Central centrifugal cicatricial (scarring) alopecia: This type of hair loss occurs most often in women of African descent. It begins in the center of the scalp. As it progresses, the hair loss radiates out from the center of the scalp. The affected scalp becomes smooth and shiny. The hair loss can be very slow or rapid. When hair loss occurs quickly, the person may have tingling, burning, pain, or itching on the scalp. Treatment may help the hair re-grow if scarring has not occurred. 

I took a saliva test (where I took samples of my saliva at 4 different times over the course of one day) that tested my cortisol. Cortisol production varies throughout the day with levels normally highest in the morning and lowest in the evening before bed (did you know that too high cortisol at night can be a cause of insomnia!). The advantage of saliva testing is that it takes cortisol levels at different times of the day and lets you know how your cortisol levels vary during the day. My results showed that my cortisol levels were below normal throughout the day. I was obviously struggling with adrenal fatigue and I’m so fortunate to have discovered this.

You can also get a hair-loss kit from Hims, which comes with both minoxidil and finasteride. Keeps has one, as well. And though it might seem like overkill to take two different hair-loss treatments at once, this is one of those rare instances where more is actually better. McAndrews calls the combination of orally administered finasteride and topically applied minoxidil a “full-court press” against hair loss. “That’s doing the most you can for preventative medicine.” Rieder notes that taking both drugs together is more effective than taking either one alone. 

Other causes for hair loss or hair thinning can be stress, illness, poor diet, hormone imbalance or your body going into shock. Certain diseases and intensive medical treatment such as chemotherapy are also likely to result in hair loss, but it is best to consult your GP if you go bald at an alarmingly fast rate, especially if you have no family history of male pattern baldness.


Despite advances in our understanding of hair loss, there are limits to current treatment. In particular, age-related hair loss and inherited forms of hair loss are difficult to reverse, although treatment may prevent further loss and produce partial regrowth. Non-surgical treatments include lotions and tablets. These generally need to be used continuously for the benefits to be maintained. If you stop treatment, regrowth will cease and hair loss will resume.  

Acupuncture is a form of Chinese medicine that has been practiced for thousands of years. Its applications are many, and some researchers believe that it may help with hair loss from alopecia areata. How? The needles inserted into the scalp may help stimulate hair follicles and promote regrowth. More research needs to be done in this area, but consider asking your doctor for a referral to a licensed acupuncturist if this treatment sounds appealing to you.

I tried various iron supplements and many of them gave me digestive issues including gas, stomach cramps, and constipation. With a life-long history of constipation, that was the last thing I needed. I have personally found this brand Perfect Desiccated Liver Capsules from grass-fed cattle works well for my body. My doctor regularly checks my iron levels including ferritin to be sure I am taking the right dosage of iron supplements for my body and that I’m not taking too much because over-dosing on iron can be dangerous.
Although many medications list "hair loss" among their potential side effects, most drugs are not likely to induce hair loss. On the other hand, cancer treatment (for example, chemotherapy or radiation therapy) and immunosuppressive medications commonly produce hair loss. Complete hair loss after chemotherapy usually regrows after six to 12 months.
Traction alopecia - certain hairstyles such as when you pull on your hair tightly can cause scarring of the hair follicles. If pulling is stopped before scarring to the scalp then your hair will grow back normally. Nervous habits such as continual hair pulling or scalp rubbing can also cause scarring and ultimately permanent hair loss. Excessive shampooing and blow-drying can also cause hair loss.

Dull hair will be the next one on the list of common hair problems that are mentioned in this article. The dull hair will not only make you uncomfortable but also make you look older than your real age. Dull hair can be caused by chemical damage, heat styling damage, improper styling techniques, and sometimes environmental soils as well as stresses, which can roughen the hair’s cuticle.
Although a fever technically is any body temperature above the normal of 98.6 F (37 C), in practice, a person is usually not considered to have a significant fever until the temperature is above 100.4 F (38 C). Fever is part of the body's own disease-fighting arsenal; rising body temperatures apparently are capable of killing off many disease-producing organisms. 

Tinea is the medical word for fungal infection, and capitis means head. Tinea capitis is fungal infection of the scalp that for the most part affects school-age children. Tinea capitis is more common in black African or African-American scalps. This condition is rare in healthy adults. Bald spots usually show broken-off hairs accompanied by a dermatitis. Oral antifungals can penetrate the hair roots and cure the infection, after which hair grows back. Sharing hats or combs and brushes may transmit tinea capitis.

Enriched with the goodness of natural ingredients such as henna, brahmi, baheda, fenugreek, jojoba oil, amla, bhringaraj, olive oil, wheat germ oil, sesame oil, this nourishing hair oil helps fight and prevent hair fall. It encourages new hair growth by stimulating the follicles, while also strengthening the hair, and reducing thinning with regular use. While on the pricier side, this oil is worth the money because of how effective it is.
When women have a hormonal disorder that causes high levels of testosterone, including polycystic ovary syndrome (PCOS), they may experience thinning of hair on the scalp. Often these conditions are also associated with acne, irregular periods, and hair growth in areas typically seen in men, says Joshua Zeichner, MD, director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City. “Over-the-counter supplements, such as Nutrafol, can help provide the follicles with the necessary building blocks for healthy hair production,” he says. These are other sneaky reasons your hair is thinning.
Biotin is a very popular supplement recommended by many doctors, pharmacists, health food stores, TV shopping channels, health websites and more when it comes to hair loss. To find some of the best supplement brands for me to try in my quest for thyroid wellness, combing the internet for customer reviews of various brands has been an important part of my process. I’ve read mixed reviews about biotin. Some users love biotin and others find no improvement or they complain about adverse reactions like acne breakout. Biotin didn’t make a significant difference for me but it might work for you and some brands get incredible reviews like this one.
A good daily multivitamin containing zinc, vitamin B, folate, iron, and calcium is a reasonable choice, although there is no good evidence that vitamins have any meaningful benefit in alopecia. Newer studies suggest that vitamin D may be somewhat helpful and worth considering. Specific vitamin and mineral deficiencies like iron or vitamin B12 may be diagnosed by blood tests and treated.
Hair multiplication. Similar to the idea of cloning, this treatment involves taking out donor cells from the hair follicles and then growing and multiplying them in a laboratory. Once sufficient samples have been multiplied, these hair cells are then injected into the bald patches to stimulate hair growth. As a relatively new treatment, hair cloning is still in its research phase.
The term "ringworm" or "ringworms" refers to fungal infections that are on the surface of the skin. A physical examination of the affected skin, evaluation of skin scrapings under the microscope, and culture tests can help doctors make the appropriate distinctions. A proper diagnosis is essential to successful treatment. Among the different types of ringworm are the following: tinea barbae, tinea capitis, tinea corporis, tinea cruris, tinea faciei, tinea manus, tinea pedis, and tinea unguium.
Minoxidil (Rogaine). This is an over-the-counter (nonprescription) medication approved for men and women. It comes as a liquid or foam that you rub into your scalp daily. Wash your hands after application. At first it may cause you to shed hair as hair follicles. New hair may be shorter and thinner than previous hair. At least six months of treatment is required to prevent further hair loss and to start hair regrowth. You need to keep applying the medication to retain benefits.
While thinning generally worsens after menopause, doctors said hormone treatments typically do not improve hair growth. Minoxidil lotion or foam, which can be purchased over the counter, is the first line of treatment. About half of women who use it have not lost more hair a year later, Cotsarelis said. Spironolactone, a blood-pressure drug, can also help, doctors said. Some may also try finasteride — approved to treat baldness in men — off-label. The evidence that it works in women is weak, Patel said.
"Despite some of the claims, a shampoo or conditioner won’t be able to stop or slow hair loss, nor help with a receding hairline or thicken hair that’s becoming thinner," says trichologist Anabel Kingsley from The Philip Kingsley Trichology Clinic in London. "At best, a thickening shampoo will make hair temporarily thicker for a short period of time, but they certainly won’t help with hair loss or thinning."
Hair Growth Essentials can be used on hair loss caused by: Hormonal imbalance, menopause, stress, hereditary hair loss, thyroid issues, alopecia areata. androgenic alopecia, female & male pattern baldness, immune system problems, infections, allergic reactions, surgery, excessive styling, hair product overuse, skin conditions of the scalp & nutritional deficiencies.

As they age, men tend to lose the hair on top of their head, which eventually leaves a horseshoe-shaped ring of hair around the sides. This type of hair loss is called male-pattern baldness. It's caused by genes (from both parents -- the idea that men take after their mother's father is a myth) and it's fueled by the male hormone, testosterone. In female-pattern baldness, the hair loss is different -- it thins throughout the top of the scalp, leaving the hair in front intact.
Hair changes about as fast as grass grows, which is to say it’s extraordinarily slow and not visible to anyone checking impatiently in the mirror every day. But during regular follow-up appointments, Harklinikken uses high-tech equipment to photograph and magnify the scalp and count new hairs and active follicles, which motivates users to adhere to the regimen. Too many people give up on treatments like Rogaine and low-level-light devices before they’ve had a chance to work, Dr. Senna said.
The cause of female-pattern hair loss is unknown, but doctors said there is a strong genetic component. The risk can come from male or female relatives. Though it looks as if the hair is falling out, that's not really what's happening. Cotsarelis said hair follicles are becoming smaller and producing hairs that may be so small that you can't see them.  Women tend to retain more normal, thick hairs than balding men do.
Androgenetic alopecia. Among adults, the most common cause of hair loss is androgenetic (pronounced: an-druh-juh-NEH-tik) alopecia. This is sometimes called male- or female-pattern baldness. This condition is caused by a combination of things, including a person's and hormones called androgens. This kind of hair loss can sometimes start as early as the mid-teen years. It also can happen to people who take steroids like testosterone to build their bodies.
1. Hair color. Anytime you dye your hair, you’re increasing the diameter of each strand, which can help add volume when your hair is sparse and fine. As a general rule, ask your colorist to make sure highlights are finer at the top of the head, where hair is the thinnest, and more intense at the bottom, where it’s thickest, says Eva Scrivo, a hairstylist and the owner of the Eva Scrivo Salon in New York City. And beware: A color that contrasts with your scalp (blonde tones if your scalp is dark, deep brunettes if your scalp is light) will make any visible scalp more obvious.
Some hair loss can also result from the psychological condition trichotillomania. “People with this condition compulsively pull out their hair when they are stressed or even when they are concentrating, e.g. studying hard,” says Burg. “Sometimes the individual doesn’t know they are pulling their hair out, doing the activity absent-mindedly, and only notice once the bald patches appear.” Over time the hair follicles can become so damaged that they die and leave permanent bald patches. Find out why you shouldn’t pull out gray hairs either.
A key aspect of hair loss with age is the aging of the hair follicle.[43] Ordinarily, hair follicle renewal is maintained by the stem cells associated with each follicle. Aging of the hair follicle appears to be primed by a sustained cellular response to the DNA damage that accumulates in renewing stem cells during aging.[44] This damage response involves the proteolysis of type XVII collagen by neutrophil elastase in response to the DNA damage in the hair follicle stem cells. Proteolysis of collagen leads to elimination of the damaged cells and then to terminal hair follicle miniaturization.
Some hair loss treatments can cause side effects. Regaine for women can cause headache, skin irritation and changes in the colour or texture of your hair. It is normal to notice increased shedding during the first two weeks of treatment with Regaine. This indicates that the treatment is working. If you find that you are shedding an unusual amount of hair after the first 14 days of treatment, stop using Regaine and ask your doctor for advice.
Harklinikken does not advertise, but the 25-year-old multinational company is beginning an aggressive expansion into the $3.6 billion hair-loss market in the United States, meaning you’re likely to hear a lot more about it. A New York clinic opened in June inside the Core Club in Midtown (you don’t need to be a member to get an appointment); and in August, Harklinikken consultations became available at some 70 Women’s Care Florida obstetrics and gynecology clinics. (Roughly 75 percent of the company’s 50,000 active users are female.)
That said, there are products that don’t have FDA approval or clearance, but may help prevent hair loss. For example, shampoos with ketoconazole, a chemical with anti-DHT properties, is widely used to treat fungal infections but has become popular among consumers as a hair loss treatment. It makes sense — research shows that ketoconazole actually has beneficial effects on hair growth (especially for those with seborrheic dermatitis).
Alopecia areata. This condition, called patchy hair loss, is the opposite of pattern baldness. Whereas in the former, thinning hair follows a pattern, alopecia areata is marked by smooth and bald patches anywhere on the scalp. The bald patches are circular, and can be as small as a pencil eraser or as big as a quarter. It begins with one or two spots that multiply on other parts of the head. The condition is caused by an autoimmune disease where the antibodies mistake the hair as the "enemy" and start attacking it, resulting into hair loss.
Most hair loss is not associated with systemic or internal disease, nor is poor diet a frequent factor. Hair may simply thin as a result of predetermined genetic factors and the overall aging process. Many men and women may notice mild physiologic thinning of hair starting in their 30s and 40s. Life vicissitudes, including illness, emotional trauma, protein deprivation (during strict dieting), and hormonal changes like those in pregnancy, puberty, and menopause may cause hair loss.
What to do: Like anemia, simple supplementation should help the problem. So can dietary changes. Find natural vitamin B in fish, meat, starchy vegetables, and non-citrus fruits. As always, eating a balanced diet plentiful in fruits and vegetables as well as lean protein and “good” fats such as avocado and nuts will be good for your hair and your overall health.

Minoxidil (Rogaine) is available over the counter and available in 2%, 4%, and 5% concentrations. It may be something of a nuisance to apply twice daily, but it has been shown to help conserve hair and may even grow some. Minoxidil tends to grow very fine small hairs wherever it is applied. It is important to avoid running the liquid onto the face or neck where it can also grow hair. It is marketed for women at the 2% concentration but may be used in higher strengths as directed by a doctor.
2. A strategic cut. Long, layer-free haircuts divert volume from the roots, making your part seem wider than it is, Scrivo says. Going shorter (than your current length — no need for a major chop) helps take weight off so hair can look fuller and bouncier. And layers that angle inward on the sides will build height and body at the crown. If you’re game to try bangs, Scrivo says, they lessen the amount of scalp that shows at the hairline.

Testosterone replacement is becoming popular for men. Cotsarelis warns that this may accelerate hair loss. Propecia might help -- but because it prevents testosterone breakdown, it might affect the dose of male hormone replacement therapy. Cotsarelis warns men taking both Propecia and testosterone replacement to make sure their doctor carefully monitors their testosterone levels.


The follicles on the sides of the scalp are more genetically resistant to DHT, which is why male pattern baldness often results in a “crown” of hair. But its downsides are serious. “With women, finasteride is not an option,” says Dr. Wolfeld. “It’s not FDA-approved for women to take, so we don’t prescribe it.” In fact, due to the drug’s effect on hormone levels, pregnant women are advised to not even touch broken or crushed tablets. 

Do not subject your hair to frequent chemical treatments, excessive blow drying, ironing, and coloring, as it can lead to hair loss. If you color your hair and have been facing hair fall issues, it would be a good idea to take a short break before you put any more chemicals in your hair. Avoid hairstyles like tight ponytails, pigtails or braids on a daily basis. Using hair elastics to pull back hair tightly can cause hair fall.
The hormonal process of testosterone converting to DHT, which then harms hair follicles, happens in both men and women. Under normal conditions, women have a minute fraction of the level of testosterone that men have, but even a lower level can cause DHT- triggered hair loss in women. And certainly when those levels rise, DHT is even more of a problem. Those levels can rise and still be within what doctors consider “normal” on a blood test, even though they are high enough to cause a problem. The levels may not rise at all and still be a problem if you have the kind of body chemistry that is overly sensitive to even its regular levels of chemicals, including hormones.
Finasteride (Propecia): This medication is FDA approved for use in only men with androgenic hair loss. Finasteride is in a class of medications called 5-alpha reductase inhibitors. It helps reduce hair loss by blocking the action of natural hormones in scalp hair follicles. Propecia is a lower-dose version of a commercially available drug called Proscar that helps shrink enlarged prostates in middle-aged and older men. Women of child-bearing potential should avoid finasteride. Propecia 1 mg tablets are available by prescription and taken once daily. Propecia may grow and thicken hair to some extent for some people, but its main use is to keep (maintain) hair that's still there. Studies have shown that this medication works well in some types of hair loss, and patients should use it for about six to 12 months before full effects are determined. This medication does not "work" in days to weeks, and its onset of visible improvement tends to be gradual. It may be best for men who still have enough hair to retain but also can help some regrow hair. Possible but very unlikely side effects include impotence or a decreased sex drive (libido). Studies show that these side effects were possibly slightly more common than seen in the general population and are reversible when patients stop taking the drug. The cost is about $70-$100/month, and most health insurers do not reimburse for the expense.
Although many medications list "hair loss" among their potential side effects, most drugs are not likely to induce hair loss. On the other hand, cancer treatment (for example, chemotherapy or radiation therapy) and immunosuppressive medications commonly produce hair loss. Complete hair loss after chemotherapy usually regrows after six to 12 months.

Rogaine’s foam squirts out just like hair mousse and is applied with “cool, dry hands.” Applying means working the foam down to the scalp where you want to see thicker growth — for it to work, “it has to get into your scalp,” Dr. Wolfeld explains. “If it sits on your hair, it’s not really as effective.” Once massaged, it dissolves into a watery liquid that leaves a tingly sensation, “but no burning!” one of our balding testers was happy to discover.


Telogen effluvium - occurs mainly due to the body’s reaction to stress, brought about by, illnesses such as cancer, mental and emotional disturbances, medications such as blood thinners, hormonal imbalances, stress during childbirth and so on. In this condition hair thinning occurs on the scalp. The hair usually regrows after the stress period is over.
Collagen is the most abundant protein in your body found in your skin, hair, bones, and tendons. Our body produces less and less of it as we age. I’ve long read about the benefits, including improved skin and nails and even pain reduction, of replenishing our depleting collagen stores with a form easily assimilated by the human body including hydrolyzed collagen and gelatin. I became particularly interested in collagen for hair loss when I read about a study published in Science in 2016. It all started with investigating the hair follicle stem cells of mice where researchers discovered that age-related DNA damage triggers the destruction of a protein called Collagen 17A1. The hair follicles of older people then convert themselves into skin cells, and over time baldness ensues. Think of the image of each hair follicle on your head disappearing leaving behind bare skin one at a time and on and on. My favorite brand is Vital Proteins Collagen Peptides grass-fed and pasture-raised.
You lose up to 100 hairs from your scalp every day. That's normal, and in most people, those hairs grow back. But many men -- and some women -- lose hair as they grow older. You can also lose your hair if you have certain diseases, such as thyroid problems, diabetes, or lupus. If you take certain medicines or have chemotherapy for cancer, you may also lose your hair. Other causes are stress, a low protein diet, a family history, or poor nutrition.

Finasteride is available on private prescription in a tablet form. It prevents the hormone testosterone being converted to another hormone called dihydrotestosterone (DHT), which is known to shrink hair follicles. Blocking this action can help the hair follicles to return to their normal size. It usually takes three to six months of daily use to see an effect, and the process starts again if treatment is stopped.
Initially used to treat high blood pressure, minoxidil was the first medication approved by the FDA to treat male pattern baldness. By applying Rogaine (or a generic version) directly to the scalp twice a day, a man in the early stages of hair loss can often stimulate growth. The American Hair Loss Association points out that results of treatment with minoxidil are limited, but it still endorses using it in combination with other treatments or as an alternative if finasteride doesn't work.
