I think Hair Cloning is too difficult to succeed.
Reason is the Immune reaction AT SKIN is GREATEST in human body.
Even heart Transplant,Kidney Transplant,Bone marrow Transplant,Liver Transplant,Corneal Transplant are all below the Immune Response power of Skin.
After reading the Immunological response of skin in medical book,i would have close the research in a single breath
Even if Hair Follicle cloning may be coming in Autotransplant,i think that will fail.
Playing with Skin Immunity is like dropping Nuclear Bomb on your own home.
My bet is that in 2030 treatments wont be much better than they are now, if at all.
