Androgen-dependent Finasteride is a medication of the 5α-reductase inhibitors (5-ARIs) class. By inhibiting type II 5-AR, finasteride prevents the conversion of testosterone to dihydrotestosterone in various tissues including the scalp. Increased<unk>  on the scalp can be seen within three months of starting finasteride treatment and longer-term studies have demonstrated increased<unk>  on the scalp at 24 and 48 months with continued use. Treatment with finasteride more effectively treats male-pattern<unk> <unk>  at the crown than male-pattern<unk> <unk>  at the front of the head and temples. Dutasteride is a medication in the same class as finasteride but inhibits both type I and type II 5-alpha reductase. Dutasteride is approved for the treatment of male-pattern<unk> <unk>  in Korea and Japan, but not in the United States. However, it is commonly used off-label to treat male-pattern<unk> <unk> . Androgen-independent Minoxidil dilates small blood vessels; it is not clear how this causes<unk>  to grow. Other treatments include tretinoin combined with minoxidil, ketoconazole shampoo, dermarolling (Collagen induction therapy), spironolactone, alfatradiol, and topilutamide (fluridil). Female<unk>  There is evidence supporting the use of minoxidil as a safe and effective treatment for female<unk> , and there is no significant difference in efficiency between 2% and 5% formulations. Finasteride was shown to be no more effective than placebo based on low-quality studies. The effectiveness of laser-based therapies is unclear. Bicalutamide, an antiandrogen, is another option for the treatment of female<unk> . Procedures More advanced cases may be resistant or unresponsive to medical therapy and require<unk>  transplantation. Naturally occurring units of one to four<unk> s, called follicular units, are excised and moved to areas of<unk>  restoration. These follicular units are surgically implanted in the scalp in close proximity and in large numbers. The grafts are obtained from either follicular unit transplantation (FUT) or follicular unit extraction (FUE). In the former, a strip of skin with follicular units is extracted and dissected into individual follicular unit grafts, and in the latter individual<unk> s are extracted manually or robotically. The surgeon then implants the grafts into small incisions, called recipient sites. Cosmetic scalp tattoos can also mimic the appearance of a short, buzzed<unk> cut. Alternative therapies Many people use unproven treatments. Regarding female<unk>  alopecia, there is no evidence for vitamins, minerals, or other dietary supplements. As of 2008, there is little evidence to support the use of lasers to treat male-pattern<unk> <unk> . The same applies to special lights. Dietary supplements are not typically recommended. A 2015 review found a growing number of papers in which plant extracts were studied but only one randomized controlled clinical trial, namely a study in 10 people of saw palmetto extract.
