Reddish-orange hair follicles
On the surface of the epidermis are hair follicles that contain numerous tiny blood vessels that transport nutrients and blood to the area. When the body develops a vitamin C deficiency, these small blood vessels in hair follicles become brittle and ultimately rupture, causing bright red and small spots on the scalp and other areas surrounding hair follicles. Perifollicular haemorrhage is caused by vitamin C deficiency and is a warning sign of acute vitamin C deficiency. Taking vitamin C supplements typically eliminates red hair follicle patches in two weeks.
