Will China Zen Shampoo pollute the scalp from white to black? Is it harmful to scalp?

Shampoo contains a lot of chemicals. If you don't clean it, it will damage your hair. After a long time, it may cause the hair tip to split and yellow, which is also harmful to your scalp.

1. Shampoo is alkaline, which will do harm to hair quality, so it must be washed clean every time you wash your hair, leaving no residue as far as possible.

2. Sodium dodecyl sulfate, which is the foam component in shampoo, is the reason why many shampoo manufacturers choose sodium dodecyl sulfate as the foam component, mainly because this chemical has strong cleaning ability. But if it is used for a long time, it will cause cancer, cause genetic variation, destroy the oil necessary for hair growth, and lead to hair loss.

3. P-hydroxybenzoate is a well-known toxic chemical, which is used to extend the shelf life of shampoo and other products. They not only irritate the skin and destroy the scalp health, but also affect the hormone balance, leading to hair loss. There is also formaldehyde, which is also contained in some shampoos. Excessive exposure to formaldehyde may lead to hair loss, which is also a well-known potential carcinogen.

Precautions for shampoo use:

1. Comb your hair with a wide tooth comb before cleaning.

2. Wet your hair and make sure the water temperature is moderate (neither too cold nor too hot).

3. Pour a small amount of shampoo (depending on the length of hair) into the palm of your hand and gently rub it with your hands to make it foam.

4. Gently rub the shampoo into your head with your fingers.

5. Wash your hair thoroughly with water. If it is difficult to clean once, you can clean it again.

6. pat your hair dry. Don't rub, pull or twist, because the elasticity and strength of wet hair are much weaker than that of dry hair.
