Progress in Relevant Growth Factors Promoting the Growth of Hair Follicle

Abstract

Hair is a protective appendage on the body that is considered accessory structure of the integument. Hair follicle development takes place during fetal skin development and relies on tightly regulated ectodermal-mesodermal interactions. The morphological changes of the hair cycle have been very clear that hair morphogenesis and epidermal development are orchestrated by an array of growth factors. In this review, we summarize the major growth factors involved in promoting growth of hair follicles.
