Greasy hair happens for a tonne of reasons. The root cause is essentially the oil and sebum produced by the sebaceous glands in your scalp. These products are actually great for hair health, and help to keep hair glossy and strong. When they build up, though, or combine with other factors and substances, they can leave hair looking slick and greasy.
This is massively heightened in warmer weather – anyone else been so hot you can actually feel your scalp sweating? Bc same, and this sweat can mix with the sebum to increase greasiness. The increase in humidity can also contribute to greasier locks, as well as sun cream being applied close to the hairline or on the scalp (centre-part gang, wya?)
All of these factors combined mean that greasy hair is sometimes inevitable during the summer months. So, what can we do about it?
