What is the growth phase in the hair cycle where new hair shafts are created?

The growth phase in the hair cycle where new hair shafts are created is known as the anagen phase. During this phase, the hair follicles are actively producing hair cells, leading to the elongation of hair strands. It lasts for several years, and the length of the anagen phase can vary significantly among individuals, with some people experiencing longer growth periods.

In this phase, the cells in the hair bulb are rapidly dividing, and as they move upward through the hair follicle, they undergo a process of keratinization, resulting in the formation of the hair shaft that we see. The anagen phase is crucial for hair health and density, as a longer anagen phase typically equates to longer, thicker hair.

The other phases of the hair cycle serve different purposes. The telogen phase is a resting stage where hair sheds. The catagen phase is a transitional stage following anagen, marking the end of active growth and the beginning of follicle shrinkage. The exogen phase refers to the shedding of mature hair. Understanding these phases is essential for comprehending hair growth patterns and addressing hair-related concerns.
