Dr. Pomerantz states, “The three stages of the hair cycle are anagen, catagen, and telogen. Anagen is commonly called a growing phase, where hair follicles continue to grow larger and deeper into the scalp to be able to support the growing hair strand. During the catagen phase, the hair stops growing, and the hair follicle becomes detached from the blood supply. Hair falls out during the telogen phase. After the follicle stays in the resting phase for 3-4 months, it returns to the [simple_tooltip text=anagen phase tooltip=The most active and longest phase of hair growth where the cells in the hair divide rapidly so as to form new hair. ].”
