What causes black heads
Sebaceous glands are located all over your body, and most of them connect to hair follicles. Blackheads and whiteheads are comedones (singular comedo). Blackheads are open comedones, and whiteheads are closed comedones. Comedones occur when a hair follicle/sebaceous gland becomes inflamed. Inflammation can occur as a result of: Increased sebum (oily material produced by the sebaceous gland) production. Abnormal formation of keratin (the protein that helps make your hair, skin and nails). Increased hormones (androgen). An increased presence of bacteria on skin that causes acne.
