It is not recommended that you wash your hair every day, which will promote scalp oil. It is not recommended that you only use one shampoo and change the two shampoos every 1 weeks, which will be better. If you wash your hair for 2 or 3 days, you can wash it a little more frequently in summer. If you don't have any strenuous exercise, you sweat a lot or get dirty, I suggest you not to wash it. Then I will give you some suggestions:

1. Adequate and regular sleep, staying up late and stress can easily cause physiological clock disorder, which will lead to hormonal imbalance, affect endocrine and indirectly promote oil secretion.

2. Avoid excessive exposure to the sun. Excessive exposure to the sun will stimulate the scalp to deteriorate and increase the protective layer of skin secretion. In fact, part of the oil is a protective layer, and excessive exposure increases the scalp secretion.

3. To reduce the intake of fried, spicy and nutty foods, we must first change our eating habits, drink more water and eat more vegetables and fruits, so as to accelerate the metabolism of the body and promote the ability of cells to detoxify.

4. Drink some tea properly, and wash your hair with the remaining tea water, which has a good effect. There are many nutrients in the tea water that can be absorbed by the scalp and can clear your brain. I hope to adopt it.
