What is sebum primarily responsible for?

Sebum plays a crucial role in maintaining the health of both skin and hair by providing lubrication. This oily substance is produced by sebaceous glands located in the skin, and its primary function is to create a barrier that helps to keep the skin moisturized and prevents it from drying out. Additionally, sebum has the ability to coat hair strands, giving them shine and reducing friction, which can minimize damage from styling and environmental factors.

The presence of sebum is also essential for maintaining the skin's natural pH balance, contributing to the skin's overall health. By keeping the skin well-lubricated, sebum helps to maintain the integrity of the skin's protective barrier, which is vital for overall skin health and resilience against external factors.
