How Are Hair Cloning, Hair Multiplication, and Follicular Neogeneis Different?

November 13th, 2006

Q: What is the difference between hair cloning, hair multiplication, and follicular neogeneis? I have read about these terms on the internet and am completely confused.

A: Cloning generally refers to the multiplication of fetal stem cells or embryonic tissues. “Hair cloning”, as the term is generally used, involves the multiplication of adult tissue cells that are used to induce the formation of new hair, so the term is not exactly accurate.

“Hair multiplication” refers to the multiplication of adult hair structures. This model is not actively being pursued since the hair follicle is too complex to be simply cultured in a tube. Instead individual cells called fibroblasts are removed from the scalp multiplied in tissue culture and then these are injected back into the scalp in the hope that they will induce intact follicles to form.

“Follicular neogeneis” is probably the best of these terms, as it describes the formation of new follicles derived from inducer cells that are cultured and then injected into the scalp. It is the preferred term of Ken Washenik at Aderans. Interctyex uses the term “follicular cell regeneration” for its technology.
