is it true that once you develop a bald spot due to some kind of damage the hair can never grow back on its own?
it depends on the degree of damage to the scalp. if you had a severe chemical burn there is a chance that it may not grow back. however if the bald spot resulted from traumatic pulling or friction -- such as from a hairpiece or a hair clip -- the hair may grow back just fine. see your dermatologist for intralesional injections of triamcinolone to help it regrow sooner. topical minoxidil may also help it regrow.
