Catagen phase

Biological Concepts

What is the catagen phase?

The catagen phase is a short transitional period in the hair growth cycle when active growth stops and the hair follicle prepares to shed.

While red light therapy primarily targets the anagen phase, supporting follicular metabolism during catagen can help preserve hair structures and delay the progression to shedding.

Understanding the catagen phase helps optimize red light therapy protocols aimed at extending the growth phase and minimizing follicle dormancy periods.
