What does the term "Catagen" refer to in the hair growth cycle?

The term "Catagen" refers specifically to the transition phase of the hair growth cycle. This phase occurs after the active growth phase, known as Anagen, and lasts for a brief period, typically lasting a few weeks. During Catagen, hair follicles undergo significant changes as they prepare to enter the next phase of the hair growth cycle, known as Telogen, which is the resting phase.

During this transition, the hair stops growing and detaches itself from the blood supply, leading to the hair follicle shrinking and the hair strand being released. This is a natural and necessary part of the hair growth cycle, allowing for the regeneration and renewal of hair. Understanding this phase is essential for skincare specialists as it informs their approach to hair and scalp treatments, addressing issues related to hair health and growth.
