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.
Best regards

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.

Your case is complex. I have no idea what densities you have or the extent of your scar and wound defect. Most people who’ve had 7 scalp reductions are left with a slot deformity. I would like to see some good pictures of your scalp from the front, top, sides, and back. I am sure that you know that scalp reduction is no longer the standard of care today, because they do not work. I have seen men who had up to 16 scalp reduction surgeries and the last ones never really accomplished anything. I wonder about your 7th procedure and what you were trying to accomplish that the prior 6 have not.
