Hair Follicle Blockage and Ingrown Hair Diagram | Dermatology Guide #3017380 (License: Personal Use)

This hand-drawn medical illustration depicts a hair shaft growing inward instead of exiting the skin surface, remaining trapped within the follicular canal. Surrounding the embedded hair are signs of inflammation-red, raised tissue-and accumulations of dark keratinous debris and cellular material, indicating early folliculitis or pseudofolliculitis. The labeled structure “Hair inside its follicle” emphasizes the pathological misdirection of hair growth.

Used in dermatology educational materials, patient brochures, or online health articles explaining ingrown hairs, razor bumps, or folliculitis. Matches user intent seeking visual understanding of hair-related skin conditions and their pathophysiology.
