Scarring can be benefited with hair transplant

The benefits of a hair transplant into atropic skin (long term balding scalp ‘skin’ is a good example) of what is seen after a hair transplant is performed.  The scalp which is often paper thin, gets thicker and this article shows why.  Many of the support infrastructure that is present in hairy scalp is not present in bald scalps to the degree that is ‘normal’; however, when a hair transplant is done, these elements repopulate again .  I have read article where someone with leg ulcers that will not heal are transplanted with healthy scalp hairs, and they regrow skin to cover these ulcers which have often been refractors to traditional treatments.  It probably can also be performed on decubitus ulcers for people who have been bedridden for long periods of time.
