Do person to person hair transplants work?

Hello Doctor, what are your thoughts on person to person hair transplants?

Person to person hair transplants only works with identical twins because with non-identical twins or other person to person hair transplants, each hair follicular unit (a complete organ system) rejects as would a kidney or a liver. I have done one set of identical twins back in the mid-1990s. It worked out fine. The reason that there was a difference in hair loss between the twins (which should not be the case) was that one twin wore a Hair System which was attached with tape and glues which pulled out the hair at the point of attachment. The donor’s identical twin didn’t use a hair system and although he had only a little bit of recession, he had not lost his hair as his twin brother did.
