    Glossary Infundibulum

    funnel-shaped upper part of a hair follicle

    The infundibulum is the funnel-shaped upper part of a hair follicle, located just below the opening of the follicle at the skin's surface. It plays a crucial role in guiding the hair shaft as it grows and emerges from the skin, and it also serves as a pathway for sebum and other substances to reach the skin's surface.
