What phase of hair growth is the catagen stage known as?

The catagen stage is recognized as the transition phase in the hair growth cycle. During this stage, which follows the anagen (growth) phase, the hair follicle begins to shrink, and the lower part of the hair strand separates from the follicle. This marks a significant change, as the hair is no longer actively growing. Instead, it prepares for eventual shedding. The duration of the catagen phase can vary, but it typically lasts for a few weeks. Understanding this phase is vital for recognizing the lifecycle of hair and how various methods of hair removal can effectively target different stages of growth, particularly the anagen phase for effective results.
