The Hair Follicle Enigma

Abstract

The hair follicle is a mini organ endowed with a unique structure and cyclic behavior. Despite the intense research efforts which have been devoted at deciphering the hair follicle biology over the past 70 years, one must admit that hair follicle remains an enigma. In this brief review, various aspects of hair follicle biology will be addressed, and more importantly, unsolved questions and new possible research tracks will be highlighted, including hair follicle glycobiology and exosome mediated cell-cell interactions. Even though bricks of knowledge are solidly being acquired, an integrative picture remains to emerge. One can predict that computer science, algorithms and bioinformatics will assist in fostering our understanding hair biology.
