The trick about all of these hair-loss products and treatments is that they’ll stop working as soon as you stop using them. “They have to be ready for a lifetime commitment,” says Rieder. But, just like brushing your teeth, as long you keep on keeping on with the scientifically proven preventative treatments, those hairs on your head should be just fine.
Some treatments in development hold particular promise for women. Angela Christiano, a hair geneticist and Columbia University professor of dermatology, is hoping to begin clinical trials in a year or two on a procedure in which she dissects hair-follicle stem cells, grows them in the lab until she has several million, then injects them into the scalp, where, a very small study done with a human skin model has shown, they induce new hairs.
Instead, you may want to add vitamin D (about $15) to your shopping cart. A vitamin D deficiency can exacerbate hair thinning and make it almost impossible for any over-the-counter product to reverse hair loss, says Dhaval Bhanusali, a dermatologist in New York City, who recommends taking 5,000 international units of D3 a day (and it’s generally beneficial for bone health in women over 40). “There’s also a link between low iron and zinc levels and temporary hair shedding, called [telogen] effluvium,” says Rogers.
There are no parabens or sulfates in the bottle. Instead, the shampoo contains biotin to strengthen hair and caffeine to stimulate the scalp. There’s also argan oil and allantoin to moisturize skin. Then, the conditioner contains another dose of caffeine plus rosemary, vitamin D, lupin protein, glycerin, and niacinamide. When used together, the shampoo and conditioner nourish strands and encourage new growth.
Also new is the HairMax Laser Comb. It's a red light therapy hairbrush-like device that increases circulation and the biological march that makes hair. It's only approved in men (though some women are using it) and in my experience, is not as good as minoxidil. But in one study, 45% of users reported improvement after eight weeks, and 90% saw improvement after 16 weeks.
"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.
Then when you’re shopping for a solution take the time to read the label, the instructions, and the reviews. We know that there are lots of fake reviews out there because we see them too. Stick to products from well-known companies and use sites like Fakespot to help you weed out the scams. Of course, a recommendation from a person you trust is a big help, too.
Unfortunately, there has been little research into female-pattern baldness. The AHLA says, "While many drugs may work to some degree for women, doctors are reluctant to prescribe them, and drug companies aren't exactly falling over themselves to test existing or new drugs specifically for their ability to prevent and treat female-pattern baldness." The only FDA-approved treatment for hair loss in women is 2 percent minoxidil, although some doctors will prescribe other drugs off-label.
Green tea is rich in antioxidants that prevent hair loss and boost hair growth (25). Many other herbal teas possess similar properties and can be used just like green tea to rinse your hair. Tea rinses have been tested and tried by many people for hair growth, and the results have been positive. Some of the other teas that you can use are bamboo tea, nettle tea, sage tea, or even regular black tea. Just steep the tea bag or a tablespoon of the dried herb in hot water and use it as described above.

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.
For example, if your hair is thinning because you’ve recently started a new medication or a diet, your approach might be to take an oral supplement or use a laser light device. But if you have hair loss from psoriasis or chemical treatments, you might try a new shampoo and invest in a moisturizing scalp treatment. Throwing everything possible at the problem might not be the most effective method.
Laser devices: Brushes, combs, and other hand-held devices that emit laser light might stimulate hair growth. These devices might make hair look more youthful in some people. Because the FDA classifies these products as medical devices, the products do not undergo the rigorous testing that medicines undergo. The long-term effectiveness and safety for these devices are not known.

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).

The other main hair-loss treatment that was recommended by all four dermatologists I interviewed is finasteride, often called by its brand name Propecia. This FDA-approved medication is only available with a prescription, but these days, it’s found as a generic and ordered online after a virtual consultation, through start-ups like Hims, Keeps, and Lemonaid.

If you think over-the-counter hair loss shampoos are for you or just want to promote growth and strength, Dr. Schwieger recommends formulas with antioxidants such as vitamin E and ginseng, amino acids, and B-vitamins to help rebuild hair and reduce environmental damage. She cautions against those with parabens, sulfates, and fragrances, which can irritate hair and reduce moisture. Ahead, eight vetted hair loss shampoos to try.
As Amazon’s #1 best-seller in hair regrowth treatments, Rogaine for Men regrowth treatment is also the #1 dermatologist recommended brand. It is also one of the top recommendations by HairLossTalk and has outstanding reviews from most users. This easy-to-use foam is the most effective method for stimulating hair growth. It features 5% Minoxidil, which is an FDA-approved medication for male hair loss. Rogaine works by prolonging the growth phase of hair and revitalizing the hair follicles to help regrow thicker hair.
Did you know the average woman is born with about 100,000 hair follicles on her head--and she keeps them for the rest of her life? Most women lose between 50 and 100 hairs a day. If your hair is healthy, it will grow back on its own. But if you're one of the 30 million women in America who experience hereditary hair loss, you may be losing 150 hairs or more a day--hair that doesn't grow back as thick and healthy as it once was.
Physicians are reluctant to prescribe systemic treatments (pills or other form of treatment that affects your entire system) because they can tamper with your body's own androgen levels (see Causes for an explanation of androgens). The doctor will first want to confirm that the hair loss is due to an excess of androgen (another name for male hormones) in the system or a sensitized "over-response" to normal amounts of androgen. Therefore, physicians often choose topical treatments, which are applied directly to the scalp.

As with transplants, the word toupee conjures an outdated and disagreeable image. The 70s-style rugs have mostly been traded in for spiffier "hair replacement systems." But the basic concept -- a foreign object atop your head -- can only evolve so far. Of course, the effectiveness of hairpieces is tough to evaluate. You may spot an awful one now and then, but the ones you do spot are just the awful ones. Who knows how many masterpieces slip undetected under the radar?


As everyone ages, hair follicles begin to shrink, leading to thinning hair (or loss of hair density). Unlike hair loss shampoos or hair thickening products that temporarily plump hair from the outside, Rogaine 2% Minoxidil Solution penetrates into the scalp to reactivate shrunken hair follicles, allowing for new fuller, younger-looking hair to regrow. Rogaine is clinically proven to help regrow hair. No topical treatment works faster to grow fuller hair than Rogaine.

When it comes to prescriptions, Propecia (finasteride) stands as the strongest oral option for treating balding. If used consistently, this hair-loss treatment stops the progression of pattern hair loss, caused by genetics, for most users -- no messy application necessary. Although the drug has yet to earn FDA approval for treatment of women, recent studies have shown that it is both safe and effective for female users. See our full review »
Some companies market special hair growth vitamins and supplements that you can buy to make it easier for you to stay healthy and help prevent hair loss. In general, however, all you need to do is make sure that you are getting enough protein in your diet (eating lots of protein-rich foods like dark green leafy vegetables, fish, eggs and beans), and the right levels of iron, zinc and vitamin A. B, C and folic acid. 

The Ultrax Labs Hair Lush treatment is an effective serum that can instantly thicken hair by up to 150%. Breakthrough caffeine innovation technology can minimize hair loss and jump-start the hair follicles to grow healthy hair more quickly. The highly effective advanced thickening treatment serum adds fullness and body to thinning hair for a fuller, thicker looking head of hair, while speeding up the production of new hair. It will leave your hair immediately thicker, fuller, and softer, and the results will get better with time.
This hair loss treatment for men from the company Kirkland Signature is a topical solution and comes with a six month supply. Each month, a 2 oz. the bottle will be used by applying the solution to the scalp. The bottles can be sprayed onto the scalp, but the solution works more effectively if applied to the fingertips and massaged into the scalp directly.
Thinning hair in women is worth investigating for more than its impact on physical appearance. While many conditions that lead to temporary hair loss will go away without treatment or with simple lifestyle measures, others may be signs of potentially irreversible loss or health conditions. Others yet may respond well to treatments to promote regrowth, so starting sooner rather than later is key.

Also known as Rogaine, this over-the-counter (OTC) medication can be used for men or women with alopecia areata or androgenic alopecia. This drug comes in foam or liquid form and is spread on the scalp each day. It may cause more hair loss at first, and new growth may be shorter and thinner than before. You may also need to use it six months or more to prevent further loss and promote regrowth.

"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."
Cimetidine, brand name Tagamet, belongs to a class of histamine blockers used mainly to treat gastrointestinal ulcers. The histamine-blocking action prevents the stomach from producing excess acid, allowing the body to heal the ulcer. Cimetidine also has a fairly powerful anti-androgenic effect and has been shown to block dihydrotestosterone from binding the follicle receptor sites.

The majority of American men and women are affected by hair loss, known as alopecia, at some point in their lives, according to experts. Androgenetic alopecia (AGA), commonly referred to as male- or female-pattern baldness, accounts for about 95 percent of hair loss in the U.S., according to Better Nutrition magazine. Experts say pattern baldness is genetic and inherited equally in men and women. However, the hair-loss gene can only express itself when dihydrotestosterone (DHT), a male hormone, is present. Because estrogen usually suppresses male-hormone production, women don't typically experience pattern baldness until after menopause has begun; although, even the slightest hormone shift can cause hair loss in women.


Beware online stores selling Propecia without a prescription.Finasteride is FDA approved, but buying it online without a prescription can be illegal and dangerous. Prescription-free online stores have a reputation for selling placebos or dangerous replacements. We recommend speaking with a doctor about prescriptions or sticking to save over-the-counter treatments.

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.


Why? Unwanted hair growth (sideburns, for example) is a reported side effect of minoxidil. The belief is that a higher concentration of minoxidil would result in more unwanted hair, which is why women are instructed to use it less often. However, the study in Skin Therapy Letter reports that unwanted hair was more common in 2 percent minoxidil solutions than 5 percent, and women are instructed to use Rogaine’s 2 percent solution twice daily — so what gives?
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?

This hair regrowth product is a one of a kind organic shampoo formulated with plant stem cells. The rare stem cells from Switzerland help to combat hair loss in an innovative and effective new way by encouraging cells that regrow to be stronger than ever. This shampoo has a mild formula which is gentle on the scalp, making it a perfect option for men who want to steer clear of topical chemical treatments while getting the same results.


Minoxidil: This medicine is applied to the scalp. It can stop hairs from getting thinner and stimulate hair growth on the top of the scalp. The U.S. Food and Drug Administration (FDA) has approved minoxidil to treat hair loss. It is the only hair re-growth product approved for men and women. A dermatologist may combine minoxidil with another treatment.
During the trials on men with prostate problems, researchers noted an intriguing side effect: hair growth. Since finasteride had already been approved by the FDA to treat enlarged prostates in men, Merck decided to pursue the possibility of developing finasteride as the first pill to treat male pattern baldness. Minoxidil, a topical liquid solution, was already on the market (see below).
Some doctors prescribe Avodart off-label (meaning to treat something other than illnesses or conditions listed on the drug's label) to patients suffering from male-pattern baldness. Dutasteride, the active ingredient in Avodart, like finasteride, is used to treat enlarged prostate glands, but it blocks both types of the enzyme that create DHT, instead of just one. Studies show that dutasteride is superior to finasteride in treating AGA, but it has yet to be approved by the FDA for that purpose.
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.
Both minoxidil and finasteride require a lifelong commitment, but for users looking for a treatment with permanent results, hair transplant surgery may be the solution. Over the years, surgeons have developed techniques to deliver natural-looking results that are a far cry from early hair transplants, which had a cornrow-like appearance. These procedures are costly and may require multiple sessions depending on the patient.
In February, though, Ms. Telford, 46, flew from her home in London, Ontario, to Sarasota, Fla., for a new $1,400 hourlong treatment known as platelet rich plasma (P.R.P.), which is said to stimulate dormant hair follicles. The procedure involves drawing blood, spinning it in a centrifuge to extract the plasma, adding various nutrients (like more protein), then injecting the resulting mixture in one-inch intervals in a grid on the top of the scalp, which has been numbed with a local anesthetic.

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.


Finally, if these tests come back normal, your dermatologist may suggest a scalp biopsy of a couple of two-millimeter sections taken from your scalp under local anesthesia ($400 and up). It can determine whether genetic hair loss, telogen effluvium (a condition in which hair falls out from stress or rapid weight gain), or a disease (such as lupus) is the cause of your shedding, and your dermatologist can treat you accordingly.

Men may also experience some sexual and emotional side effects while taking it: In a study published in the June 2011 issue of The Journal of Sexual Medicine, Dr. Michael Irwig of George Washington University found as many as 92 percent of test subjects reporting problems in the bedroom. The study also reported that “the mean duration of finasteride use was 28 months and the mean duration of persistent sexual side effects was 40 months,” meaning that side effects lingered long after subjects stopped taking the pill. 

Dr. Melissa Piliang, a dermatologist at the Cleveland Clinic, said that Rogaine works better on the top and crown (for reasons not fully understood, the frontal hairline tends to be more resistant to treatment) and ideally should be started as soon as women notice thinning. “Any regrowth you get is a minimal amount,” Dr. Piliang said. “So the more density when you start, the better results you get.”
The most common kind of hair loss is pattern baldness. It happens when hair follicles shrink and stop working. The first sign is the appearance of strands that are thinner and more fragile. Then the scalp becomes more visible as fewer hairs grow to replace those that shed. That’s because the anagen phase becomes too short for the hair to grow out of the scalp. Plus, the hairs that remain aren’t securely anchored. And this condition happens to both men and women.
