The transitional stage of hair growth is known as the catagen stage. During this phase, which follows the anagen (growth) stage, hair growth slows down and the hair follicle shrinks. This stage serves as a transition from the active growth phase to the resting phase, indicating that the hair is preparing to be shed. Typically, the catagen stage lasts for a few weeks and is crucial for the future cycle of hair growth because it allows for the eventual development of new anagen hairs as the cycle restarts.

The anagen stage, in contrast, is where active hair growth occurs, and the hair is in a healthy, long growth period. The telogen stage is the resting phase where hair is not actively growing but remains in the follicle for some time before shedding. The exogen stage represents the shedding of the hair, which allows for new hair growth to begin once again.

Understanding these stages is important for laser technicians, as each stage has different implications for hair removal treatments and techniques.
