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 pattern hair loss. Procedures
More advanced cases may be resistant or unresponsive to medical therapy and require hair transplantation. Naturally occurring units of one to four hairs, called follicular units, are excised and moved to areas of hair 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 hairs 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 haircut. Alternative therapies
Many people use unproven treatments. Regarding female pattern 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 hair loss. 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. Prognosis
Androgenic alopecia is typically experienced as a "moderately stressful condition that diminishes body image satisfaction".
In infancy the hairline starts at the top of the supraorbital ridge, but slowly recedes after puberty to create the appearance of a small forehead. References
