An oily scalp results in hair that looks oily or shiny. Your hair looks "dirty" or sticky and becomes difficult to style. The only solution is to wash your hair every day to avoid the discomfort of oily hair throughout the day.
What are the causes of an oily scalp?
Oily hair is due to an excess of sebum called hyper-seborrhea, which has several causes that can be internal or external.
A hormonal imbalance is often one of the main internal causes of hyper-seborrhea. This disorder can be linked to various factors such as stress, heredity, puberty, illness or poor nutrition. This causes an overstimulation of the sebaceous glands responsible for the production of sebum.
But there are also external causes such as pollution, too frequent washing, exposure to excessive heat (hair dryer, too hot water...), improper use of hair products or the use of too chemical products. All of these causes cause an overproduction of sebum, the purpose of which is to protect your scalp.
But what is the purpose of sebum?
Sebum is not your enemy, on the contrary. When it mixes with sweat, it forms a hydrolipidic film that protects your scalp from external aggressions, microbes and dryness thanks to its ability to retain water. It is when it is produced in excess that things get complicated... But don't panic, you just need to adopt the right gestures to stop this phenomenon!
