The best donor hair is from the back of the scalp. Body hair might be used in various clinic, however the results might not be natural. Generally, only around 500-600 grafts can be harvested from body hair. The graft survival rate of body hair on the scalp is only 50%.
The characteristics of body hair and scalp hair are not the same, for instance length, thickness, color and shading rate and cycle completely differ. For this reason, we do not encourage body hair transplant. However on special conditions like reconstructive surgery after an accident/burn or some cases of alopecia causing scars, body hair can be considered as donor.
