Sebum is a natural oil substance produced by the sebaceous glands near the hair follicles on the scalp and plays an essential role in the health and appearance of the hair. It is distributed from the hair follicles along the hair shaft and fulfills several important functions. Sebum moisturizes the hair and scalp, softens the hair and gives it shine. It also forms a protective layer that protects the hair and scalp from harmful environmental influences and microbial infections. Sebum also helps to regulate the natural pH of the scalp, promoting a healthy scalp environment.
However, an imbalance in sebum production can lead to various problems. Too little sebum results in dry, brittle hair and a dry scalp, while an excess of sebum makes the hair and scalp look oily and is often associated with dandruff or seborrheic dermatitis. It is therefore crucial to ensure a healthy balance of sebum production through proper care and cleansing of the hair and scalp.
