(female) Hi, I just wanted to say that I really appreciate the feedback you gave me about filling in the small scar on my head. I do however have another question. Since the scar on my head is so small, and I really don’t want to damage any further follicles on my head, is it possible to extract a few hairs from my leg or the back of my leg, and use it to fill in the scar? Because the hair on my legs doesn’t really differ from the hair on my head. And if transplanted, would the hair grow the same length as the rest of the surrounding hair?
Leg hair has longer sleep cycles (as does most body hair) than scalp hair and that means that most of the hair is in its sleep cycle and not showing its presence. If you transplant 10 leg hairs and watch them grow, only about 2-3 of them will be evident at any one time (the others are there, but in telogen phase). Body hair also grows at different rates and it may not grow to regular scalp hair length. Furthermore, leg hair does not have the same quality and caliber as your scalp hair. More importantly, even if leg hair transplantation works, are you willing to live with a surgical scar on your leg?
The traditional FUE procedure (on the scalp) is a better solution and the hair is exactly the same quality that exists around it. In addition, it has only a 10-20% sleep phase at any one time. Although your idea sounds interesting, it is not a worthwhile endeavor.
