However, hair follicle stem cells prefer hair destiny in vivo, unless the injury of epidimal or sytogland occurs. In 1990, Cosarelis et al. proposed "The Bulge activated hypothesis", they think the signal moleculars emit from the dermal papillar induce the downward migration and differentiation of hair follicle stem cells.

然而，体内正常情况下毛囊干细胞首先向毛发谱系定向分化，只有在表皮或皮脂腺受到损伤时，它们才进行程序重组而向表皮或皮脂腺方向分化。1990年，Cosarelis等提出毛囊的&隆突激活假说&，认为来源于毛乳头的信号因子触发了毛囊干细胞向下迁移并分化，从而维持了毛发周期的正常循环。
