1, keep the scalp clean. It is not difficult to find that when the head is dirty, it is easy to itch. I often like to scratch my head when I itch, causing scalp injury and acne injury, which makes the symptoms more serious. At the same time, as we all know, this situation often happens to people with oily scalp. Frequent shampooing can ensure that the scalp will not be covered with dirt and dust, nor will it lead to bacterial growth. Removing oiliness is also beneficial to the distribution of scalp metabolites.

2. Eat less irritating food. Irritant food refers to the hot and sour greasy food that we often eat, because the pimple on the scalp itself is caused by endocrine disorder and metabolic disorder. If we continue to eat irritating food, it will lead to more metabolic disorders and endocrine disorders, which will naturally cause irritation to the scalp. It is suggested that you can eat more light food and drink more boiled water, which is more conducive to detoxification.

3. Pay attention to changing shampoo. Some friends found that this problem did not appear before, but only recently, even after using a new shampoo. Therefore, the problem of shampoo can not be ignored. You can try a new shampoo. If it gets better, it's the shampoo. If the situation remains the same, it's not the shampoo.

4. Reasonable scalp massage. In the case of keeping the scalp clean, you can massage the scalp yourself and let the scalp tissue metabolize normally. When massaging, make sure that the scalp and palms are clean, and gently massage the scalp or hair with your hands and fingers. At the same time, friends can also massage when washing their hair, instead of scratching their heads with their hands, which is also one of the precautions of scalp massage.
