Using inferior shampoo can easily induce skin cancer

There are many factors that induce skin cancer, including chemical factors. The various chemical substances in inferior shampoos can cause damage to the skin. If used for a long time, it can easily cause cancer.

The main function of shampoo is to clean the hair and remove oil from the head. The second is to inhibit the growth of hair bacteria. Shampoo generally contains mercury, but its content has national standards, that is, the mercury content in each kilogram of product shall not exceed 1 mg. However, the mercury content in inferior shampoo may seriously exceed the standard, and contain sulfur, benzene and other substances that are harmful to the body. These substances are carcinogenic to the human body. Long-term use can lead to scalp inflammation, scalp rash and other symptoms. If it is not taken seriously, the risk of skin cancer will be greatly increased.

In addition, inferior shampoo will destroy the pH value of the scalp surface. Under normal circumstances, the pH value of the human scalp is maintained at 4.5~5.5. When the scalp encounters strong acid or strong alkaline substances that exceed its buffering capacity, it will cause scalp irritation reactions such as erythema, itching, dandruff, and hair loss.

Therefore, when choosing shampoo, you should choose products produced by regular manufacturers. Generally, some barber shops will use cheap and inferior shampoos to save costs. Therefore, when getting a haircut, you should go to a barber shop you are familiar with, or wash your hair at home before the haircut, and then rinse it with clean water after arriving at the barber shop.
