What happens to hair cells during the Catogen phase?

During the Catogen phase, which is the transitional stage of hair growth, cell multiplication ceases. This phase generally follows the anagen (growth) phase and precedes the telogen (resting) phase. During this period, the hair follicle begins to shrink and the lower part of the hair strand is detached from its blood supply, leading to a cessation of the activity that promotes hair growth. The hair is not actively growing during the catagen phase, which is why cell multiplication comes to a halt.

This understanding is vital for those studying hair growth cycles and their implications in practices like waxing, as knowledge of these phases can inform techniques and client consultations.
