A common skin condition, alopecia areata usually starts as a single quarter-sized circle of perfectly smooth bald skin. These patches usually regrow in three to six months without treatment. Sometimes, white hair temporarily regrows and then becomes dark. The most extensive form is alopecia totalis, in which the entire scalp goes bald. It's important to emphasize that patients who have localized hair loss generally don't go on to lose hair all over the scalp. Alopecia areata can affect hair on other parts of the body, too (for example, the beard or eyebrows).
Wash your hair at least once every three days with a gentle hair cleanser or shampoo to remove all the accumulated dust, dirt, oil, and bacteria build up. Keep it clean at all times to avoid hair fall from clogged follicles. It is also important not to wash your hair more than thrice a week. Overwashing will strip your scalp and hair of the natural oils that are essential for healthy hair growth.

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.
As long as the new hair that grows from that follicle is the same as the one it replaces, the hair density will remain constant. In patterned hair loss, hormones affect the follicle, making it smaller and the new hair becomes shorter and finer than the one it replaces. Eventually, the new hairs are so short and fine they become invisible and the scalp becomes bald.
Blow dryers, flat irons, and other devices: Frequent use of a blow dryer tends to damage hair. The high heat from a blow dryer can boil the water in the hair shaft leaving the hair brittle and prone to breakage. Dermatologists recommend that you allow your hair to air dry. Then style your hair when it is dry. Dermatologists also recommend limiting the use of flat irons (these straighten hair by using high heat) and curling irons.

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.
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.
Laser treatments. Low-level laser therapy (LLLT) is used for the prevention and reversal of hair loss. Also known as red light therapy, cold laser, and soft laser, it is a form of light/heat treatment (therefore generally safer) that is used on cases of pattern baldness and alopecia areata. The procedure uses a device that emits light that penetrates into the scalp. The more commonly used lasers are the excimer, helium-neon and fractional erbium-glass. The procedure can increase the blood flow in the scalp to stimulate the follicles that are in resting or dormant phase to go into anagen, and at the same time, prevent the production of DHT, which destroys the hair follicles.
Finasteride is one of the few hair loss treatments to be clinically tested, FDA approved and proven to work for the majority of men. In fact, 83% of the men who take the medicine have successfully stopped male pattern baldness and kept the hair they already have. And 65% of the men who take finasteride have even experienced a noticeable regrowth of lost hair over the course of three 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.
Dietary supplements are not typically recommended.[30] There is only one small trial of saw palmetto which shows tentative benefit in those with mild to moderate androgenetic alopecia.[30] There is no evidence for biotin.[30] Evidence for most other produces is also insufficient.[37] There was no good evidence for gingko, aloe vera, ginseng, bergamot, hibiscus, or sorphora as of 2011.[37]

Minoxidil (Rogaine) is a nonprescription medication approved for male pattern baldness and alopecia areata. In a liquid or foam, it is rubbed into the scalp twice a day. Some people have an allergic reaction to the propylene glycol in the minoxidil solution and a minoxidil foam was developed without propylene glycol. Not all users will regrow hair. The longer the hair has stopped growing, the less likely minoxidil will regrow hair. Minoxidil is not effective for other causes of hair loss. Hair regrowth can take 1 to 6 months to begin. Treatment must be continued indefinitely. If the treatment is stopped, hair loss resumes. Any regrown hair and any hair susceptible to being lost, while Minoxidil was used, will be lost. Most frequent side effects are mild scalp irritation, allergic contact dermatitis, and unwanted hair in other parts of the body.[30]
Just like pregnancy, birth control pills mess with your hormone levels, causing them to fluctuate. In response, you might experience hair loss. “Hormones can interrupt the natural pattern of the hair cycle, causing hairs to shed more quickly than usual or to grow with less vigor,” explains Dominic Burg, PhD, chief scientist for Advangen. Oftentimes the hormone responsible for this is an androgen, such as testosterone, which is why the American Hair Loss Association recommends low-androgen birth control pills for those who are at an increased risk for hair loss.
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.
Hormonal changes and medical conditions. A variety of conditions can cause permanent or temporary hair loss, including hormonal changes due to pregnancy, childbirth, menopause and thyroid problems. Medical conditions include alopecia areata (al-o-PEE-she-uh ar-e-A-tuh), which causes patchy hair loss, scalp infections such as ringworm and a hair-pulling disorder called trichotillomania (trik-o-til-o-MAY-nee-uh).

This herbal hair oil contains natural ingredients like neem, bhringraj, til oil, amalaki, japa, patola, dhattura, and narikel, which are known to help arrest hair fall. It helps strengthen and nourish the roots while also promoting new hair growth. The Trichup Hair Fall Control Oil protects hair from damage caused by chemical treatments, pollution, and styling. It improves hair texture and overall hair health.
Hair transplantation is usually carried out under local anaesthetic. A surgeon will move healthy hair from the back and sides of the head to areas of thinning. The procedure can take between four and eight hours, and additional sessions can be carried out to make hair even thicker. Transplanted hair falls out within a few weeks, but regrows permanently within months. Hair transplants, takes tiny plugs of skin, each which contains a few hairs, and implants the plugs into bald sections. The plugs are generally taken from the back or sides of the scalp. Several transplant sessions may be necessary.[33]

Finasteride is the active ingredient in the men’s hair-loss treatment Propecia, which has been available in Australia since the late 1990s. One tablet a day will arrest further hair loss in over 95 per cent of men and stimulate partial hair regrowth in two thirds of men. Regrowth may be apparent at six months, but can take up to two years to be visible.


A few studies support the use of red ginseng, sometimes called panax ginseng (about $25), for hair regrowth. It can have an anti-apoptotic effect on the hair, Rogers says, meaning it slows cell death so hair follicles can grow for a longer period of time. But before taking any of these supplements, it’s important to consult your doctor; a lab test can confirm whether you need a particular supplement or if taking it will just be a waste of time and money.
The most common form of hair loss is androgenetic alopecia, or, in other words, male or female pattern baldness or hair loss. Androgenetic alopecia is genetic and affects an estimated 50 million men and 30 million women in the United States. Among white women in the U.S., an average of 19% are affected by female pattern hair loss, but that percentage increases with age. The prevalence is nearly doubled in Australia at 32% and much lower in Korea and China at < 6%. As of 2015, no studies had been done on the prevalence of female pattern hair loss in Brazil or Africa. 

Once male-pattern baldness starts, it’s not going to stop until every last hair on your head has shrunk or shed, though the rate at which this happens differs from person to person and depends on genetics. And since the grind of hair loss is unending, it’s important to start treatment as soon as your hairline starts bothering you. If you’re looking for a more quantitative metric, Dr. Paul McAndrews, clinical professor of dermatology at the USC School of Medicine and member of the International Society of Hair Restoration Surgery, assures me that “you have to lose half your hair before the human eye can tell.” (Of course, if you don’t care about losing your hair and are fine with going full Prince William and shaving your head, go for it. We’ve got some recommendations for razors and hair trimmers to help you out on that front.) 

Telogen (Shedding Phase) - this is a resting phase, at the end of which your hair is released and it falls out, i.e., the resting hair stays in the follicle till it is pushed out by the growth of a new anagen hair. At any given time, 10% - 15 % of all hairs are in the telogen phase. The follicle then remains dormant for 3 months and the whole process recurs again.
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.
Male pattern baldness is caused by a very sensitive reaction to DHT (dihydrotestosterone) – a type of testosterone. This reaction causes the hair follicles (hair roots) to shrink and thereby lose the ability to grow new hair. This process also cuts short the lifespan of hair follicles so you lose hair more quickly. The combination of losing hair more quickly and the slow replacement rate results in baldness.

Laser treatments are the latest frontier in staving off hair loss, and they’ll be the first choice for fans of sci-fi. As silly as they may sound, these treatments do work — the American Journal of Clinical Dermatology in 2014 reported a “statistically significant difference” in hair density with no “serious adverse events” or side effects.The bad news: Laser treatments tend to be expensive, progress is slow, and they don’t always produce stellar results.
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.

“The most common cause of hair loss in both men and women is androgenetic alopecia, which is genetic pattern hair loss,” explains Dr. Michael B. Wolfeld, a board-certified plastic surgeon and an assistant clinical professor of plastic surgery at the Icahn School of Medicine at Mount Sinai Hospital in New York. The root cause of this type of hair loss is dihydrotestosterone (DHT), a byproduct of testosterone that shrinks certain hair follicles until they eventually stop producing hair.

Regarding the ferritin levels, mine fell to 8. They did five infusions of iron and got it to around 270. It has dropped to 170. I don’t feel as good as I did, and my hair is falling out again. Please explain to me the formula you use on proper ferritin levels so I might talk about with the hematologist about optimum levels for my hair. They think I’m fine at 170. I weigh 212. What should my optimum ferritin level be for my Hashimoto’s? Thanks.
In fact, hair loss cures and treatments are a dime a dozen. There are cures that are designed for temporary hair loss conditions, and others more are available for permanent cases. It's also important to note that some of these cures are specific to the cause and the type of hair loss, and other treatments don't apply for other cases such as pattern balding. We've listed them all the same in order to give you a good idea of the breadth of choices available.
Pay attention to the foods you eat and how much you’re eating. For example, eating a variety of whole foods that are rich in vitamins and minerals will help fuel your body and the areas responsible for hair regrowth. If you suspect you may be deficient in certain vitamins, visit your doctor to get a blood test and address other dietary issues, such as eating disorders or health conditions that might block nutrient absorption.
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.
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.

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.
Dealing and coping with hair loss is a particularly important issue, especially for those who lost (or continue to lose) their hair because of cancer and other chronic conditions that require chemotherapy or radiation therapy. It can be a particularly trying time, and there are instances when the depression settles in that the patient is unable to even consider or think about hair loss options and cures.

However, the high incidence of androgenic alopecia is caused by the male hormones. Testosterone in the scalp is converted into dihydrotestosterone (DHT) that causes the follicles to shrink in size, therefore inhibiting the growth of hair, which eventually leads to baldness. However, hair follicles on the sides and back of the head do not have as much DHT compared to the top, hence why hair loss is concentrated on the crown of the head. Interestingly, DHT is known to help in the growth of the beard and hair on the chest, a reason why most bald men have hairy chests and grow their beards much faster.
With those pinned down, it wasn’t hard to determine which don’t actually work. Pretty much all the “active” ingredients listed in ineffective treatments — from biotin and zinc to emu oil and saw palmetto — have never been proven, and are instead marketed based on logical-seeming correlations. It would make sense that biotin, a B vitamin readily found in hair, skin, and nails, could help hair grow more quickly. And caffeine is a stimulant that works in coffee, so rubbing some on your scalp might wake some of those sleepy follicles… right?
The pull test helps to evaluate diffuse scalp hair loss. Gentle traction is exerted on a group of hairs (about 40–60) on three different areas of the scalp. The number of extracted hairs is counted and examined under a microscope. Normally, fewer than three hairs per area should come out with each pull. If more than ten hairs are obtained, the pull test is considered positive.[27]

1. Collagen powder. Preliminary studies suggest that marine-sourced collagen may stimulate hair growth, says New York City dermatologist Yoon-Soo Cindy Bae. Though more research is needed, participants in studies reported thicker hair after three to six months of daily use. Crushed Tonic Original Powder ($105) easily mixes into coffee, tea, and water.
Instead, Advanced Hair Studio offers hair loss tablets that inhibit DHT production through naturally occurring ingredients, such as herbs. Our Serenoa 320 capsules and Advanced Hair and Scalp Antioxidant use natural ingredients, including the plant extract Serenoa as well as Fallopia japonica, Zinc, Biotin, Silicon and Ascorbic acid to reduce DHT production and create a healthier scalp.
There are few scientifically proven and FDA-approved treatments for hair loss. There are thousands of unproven claims and products to help with hair regrowth. Many conditioners, shampoos, vitamins, and other products claim to help hair grow in some unspecified way. Nioxin has been a popular brand of shampoo for hair loss, but there is no compelling evidence showing it is any more effective than regular shampoos. These products are usually harmless but generally not scientifically proven and therefore potentially useless. To slow down hair loss, there are at least four potentially effective, basic options. These include medications like Minoxidil, and Propecia, which are for long-term use. Stopping these drugs does not seem to worsen or exacerbate the prior hair loss. The patient will simply revert to the state he would have been in had he never started treatment.

The good news: Hair transplants don't look like dolls' hair anymore. The bad news: You won't be able to go anywhere to show off your new 'do because you'll be broke. The average recipient of a follicle transplant receives several thousand grafts -- strips of hair removed from bushier parts of the head -- at a cost of several thousand dollars. The cost continues to mount when patients come back for added thickness over the years.
George Cotserelis, MD, is director of the University of Pennsylvania's Hair and Scalp Clinic. He agrees that there's no evidence these alternative hair loss treatments have any effect. "If any of it did work," he says, "I'd be very worried about using that product. The fact that it’s working would mean it's doing something to the testosterone and could be having adverse effects."

"Firstly, even the very good ones won’t get to the root of the issue - pardon the pun - and prevent or treat male or female pattern baldness which is caused by genetics, nor deal with hormonal issues at the heart of female hair loss. But they can help make the hair you do have stronger and healthier. And they can be useful in putting a hair loss regime in place, along with medication like Minoxidil or Finasteride and/ or a hair transplant.
DR. WRIGHT: If stomach acid is low, protein isn’t efficiently digested – and hair and nails are made up of… protein! If we are deficient in protein, our bodies know that we can live without hair or nail proteins, but we can’t survive without heart muscle proteins or other important body proteins. So if we are short in supply of protein, the hair or nails are the first to go.
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.
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.

"I recommend that everyone [with any hair loss] take finasteride," says Robert M. Bernstein, MD. Bernstein is associate clinical professor of dermatology at Columbia University and founder of the Bernstein Medical Center for Hair Restoration. "To patients who are younger,” he says, “I also recommend minoxidil. But the mainstay is finasteride. The data show that, over five years, it significantly retards hair loss in 85% of users."


Chemotherapy is the treatment of cancer with drugs that can destroy cancer cells. These drugs often are called "anticancer" drugs. Chemotherapy is often used with other treatments. Coping with side effects (fatigue, nausea, vomiting, pain, hair loss, infection, diarrhea, constipation, fluid retention, mouth and throat problems) are important to understand when undergoing chemotherapy treatment. It is important to eat well during chemotherapy, and get the support you need both during and after treatment.
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.

Hair-fiber powders: Colored, powdery fiber sprinkles are commercially available and may work to camouflage balding areas. These colored sprinkles have special properties that help them attach to hair and give a fuller appearance. Toppik is one manufacturer of these products and can be found online. These cosmetic products are available without a prescription, are fairly inexpensive ($20-$40 range), and quite safe with minimal risk. Often these may be used in addition to medical treatments like Rogaine, Propecia, and hair transplants, and they are a great temporary measure to tide one over for special occasions.

And though this treatment appears to be safe and somewhat effective, it’s hard to tell who will react well to this low-level light therapy, which is why the doctors I spoke with were hesitant to fully endorse it. “We’re not sure what the optimal power is, what the optimal wavelength is, we don’t even really know the mechanism of action of how this is working,” says Rieder. Plus, it doesn’t work on everyone. “There are subpopulations of patients who do respond to low-level laser light, but this is not easily predictable,” explains McMichael, though she adds that the risk of using the LaserComb is low.
Being stressed affects nearly every aspect of our life—even your strands. “Stress affects hormonal levels, specifically cortisol, which then causes hair loss, which only adds more stress to an already stressful situation,” says Penny James, IAT-certified trichologist and owner of Penny James Salon in New York City. “The positive side to all this is once you reduce the stress in your life, your hair will grow back to normal.” She recommends incorporating activities such as yoga or meditation to reduce stress levels. Here’s how to repair damaged hair with items you already own.
There’s also a women’s version (Women’s Rogaine Foam) — but a three-month supply costs $22 more online. The only difference between the two products are the instructions; women are instructed to apply once a day instead of twice. If you’re a woman who doesn’t feel like paying extra for marketing, the men’s product will suffice. A cheaper generic version is Kirkland Signature Minoxidil Foam, but with a longer history on the market and more customer testimonials, Rogaine is our first choice.
