Step-by-step explanation:

Sebaceous glands are exocrine glands found in the dermis of the skin that produce sebum, an oily substance that waterproofs the skin and hair. They are associated with hair follicles and secrete sebum into the follicles, which then reaches the skin's surface. Sebum serves to prevent water loss from the skin and hair and also has antibacterial properties to inhibit the growth of microorganisms.
