What is the transition phase of hair known as?

The transition phase of hair is known as the catagen phase. During this stage, which marks a significant change in the hair growth cycle, the hair follicles undergo a process of regression. The catagen phase lasts for a short period, usually a few weeks, following the anagen phase, which is the active growth phase of hair.

During the catagen phase, the hair strands detach from the hair follicles and cease to grow. The supply of nutrients that supports further hair growth diminishes, leading to this transitional state where the hair is no longer actively growing but has not yet fallen out. Understanding the catagen phase is crucial for barbers and stylists as it impacts hair care practices and the understanding of hair growth patterns among clients.
