The sebaceous gland's primary function is to release oil, known as sebum, which is essential for maintaining the health of both the hair and the skin. Sebum plays a crucial role in lubricating hair strands and providing a protective barrier that prevents dryness and maintains moisture. This oil helps to keep hair shiny and can also reduce the likelihood of breakage.

In addition to these benefits, sebum has antimicrobial properties, which can help protect the scalp and skin from infections. The activity of sebaceous glands is also important in regulating skin pH and supporting the skin's overall barrier function. This is why the release of oil stands out as the key function of the sebaceous glands associated with hair follicles.
