How to Reduce Sebum Production on Scalp?

The sebaceous glands, present in the layers of skin and near the hair follicles, produce sebum to keep the skin hydrated, moisturised, and protected from infection. Sebum, a mixture of fatty acids, triglycerides, and cholesterol, is produced all over the body, but its highest concentration is on the face and scalp. 

When produced in excessive amounts, sebum can affect both areas. It combines with dead skin cells, sweat, and debris on the scalp, making the hair greasy and causing acne, dandruff, skin flaking, hair loss, and infection. Keep reading to learn about its causes, effects, and treatment.
