Then, in 1994, B.L. Limmer, a dermatologist from San Antonio, Texas, published the seminal paper in the field. His paper illustrated how hair grew in little patches, with a couple of hairs rooted to the same follicle. Limmer demonstrated how that those single follicles could be dissected out of a strip of scalp by using a microscope. Soon Robert Bernstein, a clinical professor of dermatology at Columbia University, took the next step and actually implanted those separated follicles back into the top of the scalp, essentially reseeding the head with hair. Thus FUT was born.
