Pregnancy may cause many changes in the scalp hair. As the hormones fluctuate during pregnancy, a large number of women feel their hair thickens and becomes fuller. This may be related to change in the number of hairs cycling in the growth phase of hair growth, but the exact reason is unknown. Quite often, there may be a loss of hair (telogen effluvium) after delivery or a few months later which will eventually normalize. 

The Rogaine rep we spoke to explained that the different packaging (and therefore different prices) has to do with the FDA-approval process: “We discovered in clinical trials that the hair loss patterns between men and women are different,” she said by way of explanation. “Men typically have that bald spot on the crown of their head, where women generally have a general thinning throughout, but concentrated more on the top of the head. So for FDA approval, we had to come up with two different, gender-specific products, so the directions were more explanatory.”
Though, it is important to point out that a lot of these companies are developing procedures that involve implanting hair, which means there is a chance they will be expensive — as we mentioned before, traditional hair transplants are costly. But a few companies and products such as Follicum’s FOL-S-005 and Fidia Pharma’s Brotzu Lotion are being designed as topical treatments.

Alopecia areata - bald patches develop on the scalp, beard, and possibly eyebrows. eyelashes may fall out as well. This is thought to be an autoimmune disease, where the immune system attacks the hair follicles and leads to hair loss on the scalp and other parts of the body. However, the hair follicles are alive so there is potential for hair to regrow when the underlying problem has resolved. Growth may occur even without treatment and even after many years. In most cases hair loss only happens in a few places, leaving a few bare patches. In some cases though, the disease can advance to total loss of hair from the head (alopecia areata totalis) or complete loss of hair on the head, face and body (alopecia areata universalis).


Men’s Rogaine Extra Strength Solution is the liquid version of our top pick. It didn’t make our final cut because it includes propylene glycol, which causes irritation in roughly one-third of its users. With that said, Dr. Wolfeld finds that it can be even more effective in practical daily use. In his experience, “the solution can penetrate and get into your scalp a little bit better” than the foam — especially if you’re not taking the time and effort to apply the foam correctly. This seems crazy to us since the foam so quickly dissolved into a liquid in our tests, but if you’re worried, try a one-month supply of the liquid and make the switch to foam if you notice any irritation.
The earlier you begin treating hair loss, the more effective the treatment will be. Androgenetic alopecia is a condition that gradually worsens over time, so the general rule is that the earlier you seek treatment, the better. “If you’re losing your hair and you have genetic hair loss, using medication such as Propecia or minoxidil is most effective when started early,” says Dr. Robert M. Bernstein, Dr. Wolfeld’s colleague at Bernstein Medical – Center for Hair Restoration. Because not everyone loses hair on the same timeline, you can’t rely on statistics to tell you when you should start treatment. Some men start to notice thinning in their early 20s, while others maintain a thick head of hair well into their 50s. If you suspect that you’re starting to lose your hair and want it to stop, act quickly.

The third and fourth stages are known as telogen and exogen, respectively. In telogen, the hair is supposed to be at "rest" until it finally detaches itself from the follicle and enters the exogen or shedding stage. Once the hair is detached from the follicle, the follicle remains inactive for about three months, after which a new cycle begins again.


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. (Learn more about acupuncture for hair loss.)
Harsh hairstyles or treatments: Hairstyles that consistently use rubber bands, rollers or barrettes, or pull hair into tight styles such as cornrows, can inflame and scar hair follicles. So can incorrectly used chemical products such as dyes, bleaches, straighteners or permanent wave solutions. Depending on the degree of damage, resulting hair loss can be permanent.
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.
One is how much emphasis the company places on compliance, the major stumbling block in the efficacy of any treatment, said Dr. Senna, an author of studies on the subject. Prospective users are questioned about their ability to stick to a regimen because the extract must be applied every day, and they are told that the more conscientious they are, the better. Users are also reminded and encouraged with regular check-ins.
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.
Generally, hair problems, especially hair thinning and hair loss, occur around the anagen phase or the resting phase. As we age, the length of the anagen phase also decreases as the hair follicles receive less and less nourishment from the body. The result is hair that is weaker and thinner after every cycle. In some cases, the hair enters the resting phase too early (or the catagen phase is too short) and this is when excessive shedding also happens.
Not surprisingly, treatments with 5 percent minoxidil work better than treatments with 2 percent minoxidil. A randomized clinical trial published in the American Journal of Clinical Dermatology in 2002 found that, in men with androgenetic alopecia, “5 percent topical minoxidil was clearly superior to 2 percent topical minoxidil and placebo in increasing hair growth.” The difference was actually pretty astounding — after 48 weeks, the men who used 5 percent minoxidil experienced 45 percent more hair growth than the men who used the 2 percent treatment.
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.
The dermatologist also will carefully look at your scalp and hair. During an exam, the dermatologist may pull on your hair. Sometimes a dermatologist needs to pull out a hair to get the necessary evidence. And sometimes a dermatologist needs to look at the hair on the rest of your body to see whether there is too little or too much hair in other areas.

Taking hair supplements can be helpful for anyone who is experiencing hair loss or hair thinning. Dendy Engelman, MD, a board-certified dermatologic surgeon at Medical Dermatology & Cosmetic Surgery in New York City, previously recommended Nutrafol, a research-backed hair supplement, to Prevention. "This uses highly concentrated botanicals to address every stage of the growth cycle," she says. Nutrafol's hair supplements include vitamin E and ashwagandha (an adaptogen that helps balance cortisol levels in the body), among others.
One of the common hair problems that will be revealed in this article is the split ends. This condition normally happens when there is a damage happening with the hair protective outermost layer, making it peel back. Women hair is more likely to suffer from split ends due to the high frequency of chemical treatments, including coloring, straightening, and excessive styling.
Cicatricial or Scarring alopecia - hair loss occurs when inflammation damages and scars the hair follicle and replaces it with scar tissue. The inflammation that destroys the follicle is under the skin surface so affected areas of the scalp may show little signs of inflammation. It is not known what triggers or causes this inflammation. If the inflammation destroys the stem cells and sebaceous glands, then hair loss is permanent.
When men have hereditary hair loss, they often get a receding hairline. Many men see bald patches, especially on the top of the head. Women, on the other hand, tend to keep their hairline. They see noticeably thinning hair. The first sign of hair loss for many women is a widening part. In rare cases, men see noticeably thinning hair. And in rare cases, women can see a receding hairline or bald patches. The reasons for this are unknown.

Androgenic alopecia is a genetic condition that can affect both men and women. Men with this condition, called male pattern baldness, can begin suffering hair loss as early as their teens or early 20s. It's characterized by a receding hairline and gradual disappearance of hair from the crown and frontal scalp. Women with this condition, called female pattern baldness, don't experience noticeable thinning until their 40s or later. Women experience a general thinning over the entire scalp, with the most extensive hair loss at the crown.
"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."
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.
While stories about hats choking off follicles or long hair pulling on the roots may be more folklore, repeat hair trauma like tightly woven hair pulled back and consistent friction can potentially worsen or cause localized hair loss in some individuals. Individuals who pull their hair tightly back in a rubber band can develop a localized hair loss at the front of the scalp.
Your body needs a way to convert hair growth  nutrients floating around your bloodstream into something it can use. Enter magnesium. This enzyme-related element assists in breaking down nutrients into useable compounds and creating new proteins for hair production. One of these compounds is melanin, responsible for giving your hair its natural color.
If your doctor recommends it, a product like minoxidil can increase hair growth in male- and female-pattern baldness. Alopecia areata can be helped by treatment with corticosteroid creams or injections on the scalp. If your doctor thinks that nutritional deficiencies are causing your hair loss, he or she might refer you to a dietitian or other nutrition expert.

Know the different types of wigs. Synthetic wigs are easy to style and are less expensive than human hair wigs. On the other hand, wigs made from human hair have a more natural look and feel, and are more preferred by those with permanent cases of hair loss. Though they take longer to style, human hair wigs are worth an investment if you plan on wearing it for a relatively long period of time.
It took me a while to decide to write this review because I wanted to have facts and not just hope. That meant waiting more than 30-60 days to comment. I am a 59 year old male. My father had male pattern baldness but until I hit about 56, I assumed I inherited my mom’s hair traits. But when I started noticing shedding I started doing research which led me to using minoxidil for about 2 years. In Jan I decided it wasn’t helping much because the shedding was still happening, so did additional research. My hair was not only thinning but the follicles were getting finer and finer. It turns out scientists don’t know all reasons for hair loss, but two common ones in men are reduced blood flow in the scalp (minoxidil is for this) and elevated levels of DHT in the scalp. It seems that if you don’t inherit the gene for hair loss then these issues don’t cause it, but if you did, then goodbye hair! After a blood test showed that I had high DHT levels in my system, I concluded that I likely had that issue in my scalp so bought Lipogaine shampoo which is supposed to block DHT and stopped using minoxidil. After 2 months the shedding was so bad I started getting very worried and restarted with minoxidil, and was using both now. By May but hair loss was so extensive that I had to wear a hat to avoid sunburn on my scalp! I hated swimming because as soon as my head was wet it was evident how thin my hair was. This led me to discovering Hair Growth Essentials and giving it a try. My wife took a picture of my receding hairline and crown on Memorial Day so we could compare for improvement. By Jun 30th my shedding had greatly decreased and I was suspecting my hair follicles were getting thicker. At that point my wife started taking it also because of her thinning hair. By Jul 30th I was pretty certain I was seeing a lot of improvement. By Aug 30th there was no question and it is a dramatic change when compared to the picture taken just 3 months earlier. My hair was thicker and denser. My wife’s hairdresser commented that she also had a lot of new hair growing in.

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.
Medical conditions and medications. A common medical condition that also causes hair loss is hypothyroidism, which can happen in both men and women. Patients suffer from an underactive thyroid gland, which is responsible for producing the hormone, thyroxin, which performs important bodily functions, such as the regulation of body temperature, proper utilization of carbohydrates and fats, and production of protein. Since protein is an important nutrient for the production of keratin, inadequate protein supply in the body due to an underactive thyroid means that hair growth in the follicles is slow. In men especially, hair loss is one of the first signs of hypothyroidism.
The test involves plucking about 50 hairs from the head, typically at the back of the scalp, so your dermatologist can look at them under a microscope and determine how much of the hair is in the resting, growth, and fall-out phases. Next, a vial of blood is sent to a lab to check hormone and nutrient levels ($100 and up, depending on insurance). If low levels of iron, or high levels of male hormones, like androgens, are contributing to your hair loss, for example, both can be treated through oral supplements or medication.
Any kind of physical trauma—surgery, a car accident, or a severe illness, even the flu—can cause temporary hair loss. This can trigger a type of hair loss called telogen effluvium. Hair has a programmed life cycle: a growth phase, rest phase and shedding phase. “When you have a really stressful event, it can shock the hair cycle, (pushing) more hair into the shedding phase,” explains Marc Glashofer, MD, a dermatologist in New York City. Hair loss often becomes noticeable three-to-six months after the trauma.
Women lose hair on an inherited (genetic) basis, too, but female pattern hair loss tends to be more diffuse, with less likelihood of the crown and frontal hairline being lost. Although some women may notice hair thinning as early as their 20s, the pace of hair loss tends to be gradual, often taking years to become obvious to others. There seems to be a normal physiologic thinning that comes with age and occurs in many women in their early to mid-30s. More women have underlying causes of hair loss than men. These include treatable conditions like anemia and thyroid disease and polycystic ovary syndrome (PCOS). These conditions are diagnosed by blood tests along with a historical and physical evidence. Although a few studies have suggested that baldness may be inherited through the mother's family genes, these theories require further testing. Current studies are inconclusive. Although not indicated for female pattern balding, spironolactone (Aldactone) has had some success in treating this condition.
While trauma can come on suddenly and unexpectedly, you may be able to help manage ongoing stress in your life with exercise, like yoga, or mindfulness techniques, like meditation. Some researchers are even exploring these alternative healing modalities in relation to reversing hair loss. The idea is that yoga and meditation may help regulate blood sugar and enhance circulation, promoting regrowth.
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.
Cyclosporine is used to suppress the immune system in psoriasis and other immune-mediated skin conditions. Although cyclosporine helps hair regrowth in alopecia areata, the risks of using it may outweigh the benefits, as oral cyclosporine can suppress the immune system and increase the risk of serious infection. Other common adverse effects are hypertension and renal impairment, but these are usually reversible.
Disruptions in the normal length of each phase, which can cause hair loss and hair thinning, may be the result of a number of internal and external stimuli. These are also what we call the triggers and causes of your hair loss. As a quick example, dieting can leave the body stressed and in need of important nutrients. Because of this stress, hair growth may be cut shorter than usual and there is an early onset of telogen or shedding of hair.

There are several different types of medication you can buy to help treat hair loss. Procepia and Finasteride are currently the only approved drugs you can take that will effectively treat hair loss. The active ingredient in both treatments (finasteride) works by blocking DHT (the male hormone dihydrotestosterone) that causes hair loss by shrinking hair follicles on your scalp. It has been proven to lead to hair regrowth or to stop hair loss in around 9 out of 10 men in clinical trials. 


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.
Surgical options, such as follicle transplants, scalp flaps, and hair loss reduction, are available. These procedures are generally chosen by those who are self-conscious about their hair loss, but they are expensive and painful, with a risk of infection and scarring. Once surgery has occurred, six to eight months are needed before the quality of new hair can be assessed.
Egg mask. Eggs are one of the riches sources of protein, which is the building block of keratin, as well as other minerals like zinc, iron, selenium, phosphorous and iodine. Mix an egg white with a tablespoon of olive oil and honey to make a paste. Apply it on your hair and leave on for 20 minutes. Rinse and shampoo using cold water. You can apply this egg mask on your hair once a week.
A good hair care regimen and diet can prevent hair loss and promote longer hair in combination with vitamins. In many cases, hair loss is caused by vitamin deficiency called telogen effluvium, which temporarily pushes hairs from the growth phase of the hair growth cycle to the resting phase, causing hair loss. Telogen effluvium is temporary and the treatment is to eat more of the key vitamins that contribute to healthy hair growth. You can prevent hair loss due to vitamin deficiency or other nutritional deficits, such as key minerals and proteins, by having a good hair care regimen and eating a well-balanced diet of hair loss foods.
Minoxidil (Rogaine): This topical medication is available over the counter, and no prescription is required. Men and women can use it. It works best on the crown, less on the frontal region. Minoxidil is available as a 2% solution, 4% solution, an extra-strength 5% solution, and a new foam or mousse preparation. Rogaine may grow a little hair, but it's better at holding onto what's still there. There are few side effects with Rogaine. The main problem with this treatment is the need to keep applying it once or twice daily, and most men get tired of it after a while. In addition, minoxidil tends to work less well on the front of the head, which is where baldness bothers most men. Inadvertent application to the face or neck skin can cause unwanted hair growth in those areas.

It is best to start treating your hair loss as early as possible, as it is easier to prevent hair being lost than to regrow it. Nevertheless, Propecia - and its active ingredient Finasteride - has proven to be an extremely successful treatment, in both preventing loss and encouraging regrowth. Although success varies according to the length of time the medicine taken, around two thirds of men who use it benefit from renewed hair growth, while hair loss is halted in most other men.
This is a short-term cure, applied while waiting for hair to grow, and therefore recommended for those with a mild to medium case of hair loss. In addition to being non-invasive, hair concealers and hair fibers are instant and affordable. Like wigs and hairpieces, they are used to effectively cover up balding spots while not getting in the way of growing hair. Compared to wigs, however, they are more natural looking and blend well with your natural hair, therefore drawing less attention when you're out in public.
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.
Every part of the body requires thyroid hormone for proper functioning, and that includes the hair follicles. In 2008, the Journal of Clinical Endocrinology and Metabolism presented the first evidence that human hair follicles are direct targets of thyroid hormones. This research demonstrated that the thyroid hormones T4 and T3 modulate multiple hair biology parameters from cycling to pigmentation.
However, researchers are still working to determine the best dose needed, whether the results are lasting, and whether they can develop a topical form of the drug, Day said. She added that patients should be aware that Tofacitinib has side effects. It's already associated with an increased risk of serious infections, as well as stomach and intestinal tears, according to Pfizer, the manufacturer.
