We learn a lot indirectly from other fields, don’t we? Hair transplantation procedures continually improve techniques and consequently, by experimentation, uncover new secrets of the hair follicle.
The so-called "stem cell hair transplantation’ procedure points directly to our field and corroborates several theories that have been doubted (ridiculed) … for decades. Specifically, the incorrect suppositions that the papilla is singularly responsible for the follicle’s ability to generate a hair AND that hairs can only be removed in anagen phase.
Go on-line and research this yourself: "stem cell hair transplant.’ Watch the animated videos and "connect the dots.’ Surgeons are now removing only part of the follicle, containing stem cells, and leaving a portion of the follicle in-place. In most cases, both the dissected follicle and the remaining follicle regrow a hair. The dissected follicle has no papilla … and yet is able to grow a new hair. BINGO!!!
From this procedure it’s now a certainty that follicle stem cells, not "papilla only,’ are crucial to hair growth. In telogen, all the stem cells are still present … but "disconnected’ from the papilla. So, there it is! Versteh?
In 40-years of doing electrolysis, people have told me that "hairs can only be removed in anagen.’ Shit … I’ve been removing "hairs in telogen’ my entire career (and so has Josefa … who has been ridiculed about this), but now the science is in. The "anagen only’ and "papilla only’ theory are simply wrong.
One difficulty (perhaps) is the way the skin and follicle are usually depicted. Usually the epidermis is drawn gigantically too thick and, most importantly, drawings show only papillae that are associated with follicles. (I’ve done this too in my illustrations!)
However, this is not the case: you have billions of papillae and they lie just under the epidermis … BILLIONS of them (they "feed’ the epidermis). Maybe that’s why we think that papillae are associated with hair follicles ONLY. They’re not! Ummmm, that’s probably why the upper dermis is called "the papillary dermis?’ Dr. Bowman (Holland) … after tons of experimentation … told me he thought a dissected hair follicle "finds’ a new one!
At least consider the science and don’t hang on to ancient "superstitions.’
