This board used to have good posts about hair research news and people were curious and tried to explore progress them self. I miss those days, there were actually threads worth reading then.
anyway. This could be Follica related. Could have nothing to do with it. But Rox Andersson, one of the follica scientific founders, has a new patent out regarding substance delivery to follicles. http://v3.espacenet.com/publicationDetails/biblio?DB=EPODOC&adjacent=true&locale=en_EP&FT=D&date=20101216&CC=WO&NR=2010144257A1&KC=A1
This could possibly hint on where Follica have problems moving forward, maybe it´s not the wounding technology that needs improvement but the delivery of growth factors etc to the scalp.
Another indication of this theory is that every DIY experementing with topical egfr inhibitors has failed doing this. But some of us has probably seen that scalp wounding sometimes can result in tiny, sparse vellus hairs. So wounding it self works to some extent.
