I think that the hair loss is not a problem of degenerating of the hair or a genetic predisposition of the hair to fall, but it can be a degeneration of the skin where the bald area apears. May be a transplant of the hyperderm from other part of the body to the bald area may help the regeretion of the skin and the hair . Or the injection of the fat from other part of the body taken by liposuction to the hyperdermis of bald area may have an efect.
The skin has nothing to do with hair loss, unless it is diseased. Transplanting skin would be human experimentation with no back-up clinical trials and skin transplants might very well kill the hair. Fat transplants also will do little to help grow hair.
