Body hair can also be used to supplement scalp tresses, but this is not common and is only done in exceptional cases. But the clinics do not suggest using body hair to wrap a bald hairline on a regular basis. There are several explanations for this, including the fact that body hair doesn’t really fit head hair, the rate of increase of body hair implants would be less than 50%, and they end up causing more abscess and blemish forming.
