    GlossaryHair Growth

    process where hair strands develop from follicles in the skin

    Hair growth refers to the process by which hair strands develop from hair follicles located in the skin. This process involves three main phases: anagen (growth phase), catagen (transitional phase), and telogen (resting phase). During the anagen phase, cells in the hair bulb divide rapidly, adding to the hair shaft and causing it to lengthen. Factors such as genetics, hormones, and overall health can influence the rate and quality of hair growth.
