Antwortdetails

The oily substance that lubricates mammalian hair is secreted by the sebaceous glands. These glands are located in the skin and produce sebum, an oily substance that helps to keep the hair flexible and water repellent. Sebum also has antibacterial properties and helps to prevent the hair and skin from drying out.
