Home-Questions Answers Hair - Sebaceous gland

Sebaceous gland

The sebaceous gland is a gland present in the dermis (under the skin) which secretes a sort of grease or oil called sebum. The sebum secreted by the sebaceous gland protects the skin from external factors such as drought, cold and bacteria. The sebaceous gland is usually connected to a hair follicle. On the scalp, secretions produced by the sebaceous glands are sent to the top of the hair follicle in order to lubricate and protect the hair.
