Did you mean Catagen Induction?

GlossaryCatagen Induction

process triggering hair follicles' transition from growth to regression

Catagen induction refers to the process that triggers the transition of hair follicles from the growth phase (anagen) to the regression phase (catagen). During this phase, hair growth stops, and the hair follicle shrinks and detaches from the dermal papilla, preparing for the resting phase (telogen) before the cycle starts anew. This process is crucial for the natural hair growth cycle and can be influenced by various factors, including hormonal changes and certain medications.
