The sebaceous glands found in the scalp produce a natural fat that protects the hair, keeping it hydrated and healthy. But when this hair fat is produced excessively, the hair becomes oily.
When this happens, it may happen that the fat is so much that it chokes the hair root, and the hair begins to fall or dandruff appears. This gives the hair a sloppy look, it may look unkempt, greasy, and even smell bad. There are many reasons why this excess hair fat is produced, now we will see some of them.
The causes for which a person has oily hair, can be several. It may even have a natural cause that is intensified by improper action. Therefore, here we will present the most common causes, natural or not, associated with oily hair:
Although it may seem unusual, the type of hair can be inherited as other factors are. That is why you can see in the same family a characteristic type of hair. If this is your case, and you have oily hair, you may notice that one of your parents, grandparents or siblings also has it.
When people suffer from stress and depression or some other disorder, their body produces cortisol and more fat is secreted than normal.
Some hormonal disturbances contribute to increased fat production, such as occurs during puberty or pregnancy. Even some medications, such as birth control pills and some antidepressants, also cause this alteration.
Poor hair care
Excessive washing with very aggressive chemicals can affect the pH of the skin of the scalp and cause excessive secretion of the sebaceous glands.
Rubbing the scalp very hard when washing the hair or with the towel when drying it can also overstimulate these glands and cause an excessive production of sebum.
Very thin hair
It is often observed that people who have very thin or straight hair also appear to have more oily hair. I’m have an explanation, each hair has a pair of sebaceous glands that moisturize it. Being too fine, the excess fat remains on the surface and accumulates. By touching or combing it, we can dissipate it and spread it on the rest of the hair
How to Properly Treat Oily Hair
As you may have noticed, one of the main reasons that hair becomes greasy, lies fundamentally in the excessive production of sebum by the sebaceous glands.
In this sense, most of the recommendations made by experts in relation to this problem are aimed at avoiding over stimulation.
Based on this, remember to wash your hair about twice a week. Preferably in the morning since this is when these glands are least active.
Use warm, not hot, water and preferably let the hair dry naturally. Avoid the use of dryers and irons as well as rubbing or combing the hair excessively or abruptly. Try combing your hair with wide-toothed combs and not using brushes.
Eat low-fat foods, and drink plenty of fluids.
Don’t use conditioner. You can make clay masks or use essential oils such as peppermint oil.
