Can Hair De-Miniaturize?

Hey Dr. Rassman,

I like your site and all the time you devote to it to help the readers. I have a little bit of miniaturization going on at my temples (I’m 20). I went and saw a hair transplant doctor and he explained to me the process of the “mature hairline” (although he didn’t call it that). He also said that sometimes hair can miniaturize and then come back again (de-miniaturize) healthy on its own in young men as they grow. I was just wondering what your professional opinion was on this statement. Would you agree? Have you seen that happen? Thanks for your time.

Generally when miniaturization occurs in men, it is permanent if it is associated with genetic hair loss. If the miniaturization is part of the maturing hairline, then this too should be permanent. Miniaturization caused by DHT and genetic balding will not reverse on its own, but may reverse with finasteride (Propecia). I do not believe that there is spontaneous reversal of miniaturization in the genetic process, at least not in most of the miniaturization seen in men. With regard to women and miniaturization, the same rule may apply, but we unfortunately do not have enough information to make certain one way or the other.
