Why can't I get a hair transplant from another person?

Hair transplant surgery is not a medical necessity.  It is an elective cosmetic surgery.If you find a willing doctor and a willing dead donor you can try hair transplant from another donor.You pose an interesting question but the practicality, safety, and the logistics of how to go about doing (for a cosmetic surgery) may be a greater challenge.

Good question, I read the study and had the same question myself. Practically speaking, the issues becomes how well those papilla cells recreate a normal, scalp appearance. Current hair transplant moves dermal papilla as well as dermis and as you know works very well.  So if they are truly rejection immune, will they ultimately look aesthetically pleasing.  I am interested in a wider discussion/analysis.Dr John Frank, MD

The mechanism behind dermal papilla cells is not entirely clear but appears to be cloning (the papilla cell dna is incorporated to the new follicle). The problem is the papilla cells need to be grown in a tissue culture (outside the body) in large quantity, and this process has not been perfected. Likewise this needs FDA approval before trying on humans which will take awhile, and even then we don't know if the new hairs will last. So for now, hair transplant is still our best option. However, this is exciting research.
