Which stage of hair growth represents the transitional phase?

The transitional phase of hair growth is represented by the catagen stage. During this phase, which follows the anagen (active growth) phase, the hair follicles begin to shrink and the lower part of the hair strand is destroyed. This process allows the hair to prepare for the next stage of the cycle, which is the telogen phase. In the catagen stage, hair growth ceases and the hair is no longer actively involved in the growth process, indicating a significant change in the hair's life cycle. Understanding the distinct characteristics of the catagen phase is crucial for recognizing how hair transitions between states, as this impacts hair health and growth patterns. This delineation sets catagen apart from the anagen phase, where hair is actively growing, and the telogen phase, which is the resting phase preceding hair shedding.
