I have read that finasteride is successful in slowing/stopping hair loss in the crown and mid-anterior scalp areas of the head and in some instances stimulating regrowth. I notice that there are many statements saying that there is no statisitcally significant evidence in showing that finasteride works in the temple area of the scalp. Why is this? Don’t these follicles miniaturize as an effect of DHT in these areas as well? Thanks for your time.
I do not believe that the drug companies have studied the frontal area with enough effort to help us define what you are talking about. Why? I have no idea. But just because there are no studies, it does not mean that the medication is not helping in the frontal area. I believe that reversal of miniaturization does occur in the front, as well as the more frequent observation that hair loss slows or stops in the front with finasteride. Most of the time the hair that is saved with finasteride is in the crown where early thinning starts and has more miniaturization than frontal hair, but I’ve seen hair reverse in the frontal area as well.
With regard to the temple prominences on the side of the head, I suspect that a prevention of hair loss occurs there, but there is no evidence one way or the other to back up my suspicion that I can point you to.
