Oily hair

What causes oily hair?

Every pore on your skin has a sebaceous gland, including your scalp. Better known as oil glands, these are responsible for maintaining proper hydration levels by producing sebum (oil). When it comes to your hair, sebum is responsible for giving your strands a healthy shine. However, some sebaceous glands produce excess oil, making your hair greasy. If you have oily skin, then you’re more likely to have oily hair.
