I had a hair transplant 15 months ago and my transplanted hair is very wiry, dry, and frizzy. Before the hair transplant it was straight. I have read a number of posts indicating that this condition is quite common, but at 15 months I'm beginning to get concerned. Everything I read seems to indicate that the texture will return to normal. Has anyone ever heard of cases where the hair texture does not return to normal? Is it possible that I just need to wait longer for the texture to change back?
