Avodart is the new prescription from GlaxoSmithKline for reducing DHT. Dihydrotestosterone (DHT) is the main hormone linked to hairloss. Avodart prevents one of two enzymes from being converted into DHT and blocks 2/3 of the DHT production. The new prescription Avodart blocks both enzymes in the body that convert into DHT and reduces overall DHT production by over 93%. Avodart comes in a 0.5mg softgel capsule that is taken by mouth once per day.
