I had a tranplant with armani last monday on the hairline, 2500 grafts. Are the transplanted hairs guarunteed to fall out before they regrow, or could some of them stay? Also, I need to go to classes for a few hours a day and that requres me to wear a hat. I know its says two weeks for a hat, but it doesnt hurt at all when i wear it and its only for a few hours a day. could this do seriuos damage to my results? thanks.
