Dandruff is also a reason for hair loss. And this occurs as a result of dry scalp, and use of chemical products. So once you start using olive oil, it helps in keeping the scalp moisturized by deep penetration, and as mentioned, it also acts as a damage-control. Hence, dandruff does not remain an issue when you start using this oil. And so when there is lesser dandruff, hair loss is reduced and hair growth is enhanced.
