Is it too dry? Is my newly washed hair itchy?

1. Wash your hair frequently: Don't wash your hair often. Because there are protective substances on the scalp and hair surface, washing your hair every day will destroy this protective layer and the scalp will become dry and itchy. Generally speaking, it is best to wash 1 ~ 2 times a week when it is not easy to sweat and the hair is not dirty. Wash once every 3 ~ 4 days if necessary.

2. Use inappropriate shampoo: Everyone's hair is different, so choose a shampoo that suits you. Do not use alkaline soap when washing your hair, because soap will stimulate the keratinization of scalp epithelial cells and produce dandruff. It is best to wash your hair with sulphur soap or shampoo.

The chemical damage of shampoo also has a great influence on hair and skin, especially for people with a lot of dandruff. When washing their hair, they should pay special attention to foaming the shampoo before putting it on their hair.

The solution of scalp itching:

1, beer: It may be a pity for people who like beer, but there are also many people who wipe their hair with beer every week or two, and the effect is very good. It can not only protect hair, but also promote hair growth.

When in use, the hair is washed and dried first, then one eighth of the beer is evenly spread on the hair, and then the beer is massaged by hand and infiltrated into the hair roots. After 15 minutes, it is washed with clear water and combed with a comb. The effective nutrients in beer have a good therapeutic effect on hair withering and shedding, and can also make hair bright.

2, baking soda: First of all, baking soda is a food raw material, edible, so it can also be used to wash hair, which is one of the natural substitutes for shampoo. Its chemical name is sodium bicarbonate, which is an acid salt produced by neutralization of strong base and weak acid. When dissolved in water, it is weakly alkaline, and the weakly alkaline solution has a strong ability to remove grease, so it can relieve scalp itching symptoms.

The ratio of baking soda to water is generally 1:2, which means that 500 ml of water and 25 g of baking soda (2 tablespoons) are mixed. Please be careful that the water temperature is not too high, it will decompose baking soda. When the mixed aqueous solution is fully contacted, gently massage the scalp 1 min, and then rinse it off.
