I know there is a better chance for reversal for men in early 20s, but what I meant to ask… Are men in their early 20s (more likely to have rapid hair loss) more likely to not respond well to finasteride than men in their late 20s or early 30s? As a doctor, have you ever encountered men (after the age of 25) who didn’t respond well to fin (couldn’t maintain) and still lost their hair due to generics winning the battle? If so, is it more uncommon for men after the age of 25?
Generally speaking, balding men in their 20s have more hair loss than balding men in their 30s. Men with advanced hair loss patterns have most of the hair loss occur before they are 25. If you are over 25 and don’t have an advanced pattern of balding, you are probably not one of the aggressive balding patients. Finasteride works well in men in their early 20s or late teens, still well in their late 20s, and then less well the older you get. Nonetheless, it still works.
