From what I’ve seen and read they can be quite effective–but come with several risks (scarring and unnatural-looking hairline come to mind). I haven’t dwelled much into it, but basically got FUT (follicular unit transfer), FUE (follicular unit extraction) and DHI (direct hair implant)–which is the newest, similar to FUE, most costly and provides the best results in most cases.
About one-third of women experience hair loss (alopecia) at some time in their lives; among postmenopausal women, as many as two-thirds suffer hair thinning or bald spots. Hair loss often has a greater impact on women than on men, because it's less socially acceptable for them. Alopecia can severely affect a woman's emotional well-being and quality of life.
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.
The truth is, the amount of propylene glycol in hair loss treatments is not likely to cause any real harm and the FDA has given the chemical approval for many uses. But even though it is safe, we wanted to ensure that our top picks would be as comfortable to use as possible. So when Dr. Khadavi told us that “a third of my patients get irritated from minoxidil products because of propylene glycol,” we decided to cut any treatments with it. In any case, it’s the minoxidil that helps curb hair loss and not the propylene glycol.
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.
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.
Results from clinical studies of mostly white women ages 18 to 45 years with mild to moderate degrees of hair loss report that after using minoxidil for eight months, 19% of users had moderate regrowth and 40% had minimal regrowth. Of those using a liquid without active minoxidil (a placebo) during the same time period, 7% reported moderate hair regrowth while 33% had minimal regrowth.
These anti-androgenic effects can be used to help treat hair loss. Nizoral shampoo contains 2% ketoconazole and is prescribed not only for the treatment of scalp conditions, but also in combination with other treatments for androgenetic alopecia. A 1% version is now available over-the-counter, but it may not be as effective as the 2% prescription strength. There are no significant side effects.
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.
