1, washing your hair too often also gives you oil.
As we all know, if people don't wash their hair for a long time, their hair will become oily. This is because the scalp can't be cleaned in time, which leads to excessive accumulation of oil secretion and greasy hair. In fact, if you wash your hair too often, you will get oil. This is because our bodies only secrete oil according to information feedback. The more times you wash your hair, the cortex will send out a signal of oil shortage after the oil on your head is washed clean, and then the scalp will continue to secrete oil, resulting in excessive oil secretion, and the problem that the hair is washed more and more oily will appear.
2, eat greasy, spicy, bad habits.
Many people usually like to eat high-calorie and high-fat things. If they usually eat too greasy and spicy, it will also stimulate our sebaceous glands to secrete oil. And now many young people like to stay up late and play computer for a long time, and their life pressure is too great. Irregular life will also affect the endocrine system of the human body and aggravate hair oil.
This shampoo contains silicone oil.
In addition to the above two reasons, there is another reason, which is about shampoo. When we buy shampoo, we will definitely hear about silicone oil. Silicone oil is polydimethylsiloxane in the shampoo ingredient list, which is also the silicone oil that we often say has the function of lubricating hair. This substance is insoluble in water in liquid state, but soluble in oil. When you wash your hair, it contains this substance, which will make your hair smoother and of course lead to faster oil production.
Therefore, it is best to control the frequency of shampoo once every 2-3 days, which can not only ensure the cleanliness of hair, but also effectively maintain the grease on the scalp. If you find that your hairstyle is not very good after getting up in the morning, you can rinse it with clear water and try not to use shampoo frequently.
