I read from another post on another forum, that someone went to a hair hair transplant doctor worried that he was balding. The hair at the back of the head was thick and black, and the hair at the top was thinner and lighter. The doctor tugged his hair and it seemed fine, and he told him - "-it's normal for hair thickness and texture to vary across the scalp."
Is this true? The whole reason I'm in these forums is I've noticed a section on the top-left side of my head where the hair is thinner and lighter, although the hair does not come out if tugged and there is no shedding.
