hair bulb
Root's growth center
The hair bulb is the rounded base of a hair follicle, located beneath the skin's surface.
It contains the cells that divide and grow to form the hair shaft.
The bulb surrounds the dermal papilla, which supplies blood and nutrients for hair growth: Damage to the hair bulb can cause permanent hair loss.
