Does anyone know if topical dut also protects hair from free testosterone? I know it's supposed to do a good job of protecting your hair from DHT, but was curious if it protects hair from free testosterone which, as i understand, can also attached to the hair follicle and do damage, although much less compared to DHT. I know people use RU and CB topically but was curious about this. i guess i'm not totally sure how topical dut works. does it attached to the receptor in the scalp so that test doesn't convert to DHT in the scalp?
