A sebometer is an instrument used to measure the amount of sebum on the scalp. Sebum is an oily substance produced by the sebaceous glands of the scalp and is essential for maintaining hair health, but excess sebum can cause problems such as seborrheic dermatitis, dandruff, and hair loss.
Additionally, the sebometer can also help determine the effectiveness of hair products used to control excess sebum. Hair products that reduce the amount of sebum produced may be recommended for those with excess sebum. With this information, steps can be taken to control excess sebum and improve hair health.
