Catagen is the transitional phase of the hair follicle from the active growth phase (anagen) to the resting growth phase (telogen) in the hair growth cycle.
Hair cycle consists of three major phases: anagen (August to October), catagen (after December), and telogen (after February) [2].
The HF is a particularly useful system in which to study SCs and their progeny since hair growth is fueled by SCs during development, and in adults, the HFs continuously regenerate in alternate cycles of growth (anagen), destruction (catagen), and quiescence (telogen) [29].
Each cycle consists of a long growing phase (anagen), a short transitional phase (catagen) and a short resting phase (telogen).
