I hear eveyone talk about adult hairlines, and I was wondering if someone at twenty three can just develop their adult hairline and the recession will stop. The right side of my hairline is very strong and has not changed since what I had at age like 15. But, my right side is moving back some. I have alot of hair it is all just fine. But it has been like that my whole life. Is it possible to receed on one side and not the other?
