Prognosis
Men
Androgenetic alopecia in men aged between 18 and 60 years can be effectively treated with topical minoxidil or oral finasteride. Treatment is continued indefinitely, although peak hair growth with topical minoxidil solution is achieved after 4 months and with oral finasteride after 2 years. There is a 66% maximum increase in hair growth with finasteride.[40] If treatment is discontinued, any positive hair growth effect will be lost within 6 to 12 months.[15][40]
Women
Treatment produces moderate efficacy. Treatment is recommended to be continued indefinitely to maintain effects.[31][48]
