Olive oil is beneficial to the hair because it provides moisture and antioxidants, such as vitamins A and E. These vitamins protect keratin in the hair while locking in moisture. Olive oil also acts as an antimicrobial agent, helping prevent dandruff and lice.
Olive oil prevents sebum accumulation, which hampers hair growth. The oil is found in many commercial hair products, but olive oil can be applied to the hair at home, and it is a natural conditioner. The antioxidants found in olive oil promote scalp health and treat hair loss. Olive oil improves blood circulation in the scalp, which stimulates the hair follicles. It also reduces the negative impact of the DTH hormone, which is responsible for hair loss.
