Does Dhea cause hair loss? If it does, when it is discontinued can the hair grow back or is it too late. Also can Retin A be used by itself to regenerate hair loss? Also can topical melantonin have any value. As a dermatologuist, i can tell you that rogaine and propecia are close to worthless.
DHEA can cause hair loss. When it happens in men, it often triggers or accelerates the genetic hair loss and in men, this is often not reversible. Retin A can not regenerate hair, nor can topical melatonin.
Your comment about the value of both Propecia (finasteride) and minoxidil does not reflect my thinking nor my clinical experience. I have seen people completely reverse on Propecia — see Propecia Patient Results (with Photos) for one example.
