Hello and welcome to healthcaremagic. Androanagen contains Saw palmetto extract and is useful for Androgenetic hair loss. It acts by inhibiting an enzyme (5 alpha reductase, present in hair follicles) involved in the conversion of testosterone to Dihydrotestosterone(DHT). DHT is responsible for thinning and hair loss from the front, vertex and crown of the scalp. Androanagen therefore is useful for this kind of patterned hair loss in males known as Androgenetic alopecia. It works best when used along with topical Minoxidil. Minonxidil is US FDA approved for this kind of hair loss in males regards
