Pennsylvania Esthetician State Board Exam Practice 2026 – Full Prep Guide

The stage where hair begins to destroy itself as it disconnects from the papilla is known as the catagen phase. During this transitional phase, which occurs after the active growth period of the anagen phase, the hair follicles shrink, and the hair shaft separates from the papilla, the part of the follicle that provides nourishment for hair growth. This process marks the beginning of the end for the hair strand, as it prepares to be shed.

The catagen phase typically lasts for a few weeks, during which the hair stops growing and is effectively in a dormant state. It’s an essential part of the hair growth cycle, allowing for the eventual shedding of older hairs to make way for new growth. Understanding this cycle is critical for estheticians as they assess hair growth patterns and related treatments.

Other stages mentioned, such as the telogen phase, are involved in hair shedding but occur after the hair has already gone through the catagen stage. The anagen phase is when active growth occurs, and the villus phase refers to fine, unpigmented hair typical in areas of lesser body hair density. These phases serve different roles in the hair life cycle.
