But is this mechanism backed by any scientific evidence? Read on to know what research has to say about finasteride as a treatment for hair loss.
What Does Research Say About Finasteride For Hair Loss?
Finasteride, in laboratory experiments, has shown to reduce male pattern baldness (‘M-shaped’ balding) in men and female pattern baldness (thinning of hair throughout the scalp) in women. Let us have a quick glance at those studies. Japanese scientists tested the effect of 1 mg Finasteride on 2,561 Japanese men with androgenic alopecia (male pattern baldness). Hair count increased greatly in 11% men, moderately in 36.5% men, and slightly in 39.5% men. Also, the response rate had improved with an increase in the treatment duration (5). Another study by American scientists found that 1 mg/day of finasteride slowed hair loss and boosted hair growth in men over a 2-year treatment period (6). A review paper in the Journal of Drugs in Dermatology observed that topical application of finasteride decreased plasma DHT in men and women (7). Sixty-five men with androgenic alopecia were treated with a combination of finasteride 1 mg/day and topical application of 5% Minoxidil. Both the medications could treat mild to severe male pattern baldness (8). Excessive testosterone production in some women may lead to irregular periods, hirsutism (hair on the face, chest, and back), and androgenic alopecia (9). Finasteride is not effective and possibly dangerous for women of childbearing age. However, a 67-year-old lady without hyperandrogenism (excess body testosterone) showed significant hair growth when treated with finasteride 5 mg for a year (10). In another study, 37 pre-menopausal women were administered with 2.5 mg finasteride and an oral contraceptive. 62% of the patients showed a reduction in hair loss. Finasteride 5 mg/day administered to 87 pre-menopausal women for a year showed increased hair thickness and density in a separate study (11). Finasteride, alone or with minoxidil, is an effective drug for treating male pattern baldness. However, more studies on women with larger sample sizes are warranted (considering their menopausal and hyperandrogenism status). But at what optimal dose does finasteride work?
