Sebaceous Glands

Sebaceous glands are connected to adjacent hair follicles by a short duct. They provide oil for the hair and outer skin by producing sebum, a mixture of waxes, fatty acids, cholesterol and debris of dead cells. Sebum retains moisture, keeping hair glossy and skin pliable. Sebum also can kill certain forms of harmful bacteria.
