However, Dr. Barry DiBernardo, who has a private practice in Montclair, N.J., said the procedure does raise a few questions and concerns.
"Finding hair from other parts of the body is not new at all," he noted. "We've long considered that option, because clearly when you're designing a hairline . . . the more we can make it look like what was there in the first place, the better," DiBernardo explained.
"But when you use body hair it can be a different thickness," DiBernardo said. "It can have more curl to it than the original hair. So these reports sound fine. But the approach does raise the issue of a hair mismatch, which of course will depend on the person. Everybody varies," he said.
"The other thing is the question of the potential for scarring, or leaving pinpoint scars, following harvesting of hair," DiBernardo pointed out. "Because while you're not going to see the back of the head and it's a very good area for healing to begin with, you will see the leg. And the leg certainly doesn't heal as well as the scalp."
