What phase follows the active growth phase of hair in the hair growth cycle?

The phase that follows the active growth phase of hair, known as the anagen phase, is the catagen phase. During the catagen phase, which is a transitional stage, hair growth slows down, and the hair follicle shrinks. This phase typically lasts for several weeks and acts as a bridge between the anagen phase (the growth phase) and the telogen phase (the resting phase). It is essential because it prepares the hair for eventual shedding.

Understanding this cycle is crucial in esthetics, especially when considering treatments that may affect hair growth, such as laser hair removal or other hair restoration therapies. The other phases serve different purposes and occur at different times in the hair cycle, but the catagen phase specifically marks the transition from active growth into the resting phase.
