What ingredients can't be used in shampoo?

Hazard: inhibiting hair growth+causing hair loss+carcinogen.

As a foam component in shampoo, many shampoo manufacturers choose sodium dodecyl sulfate, which has strong cleaning ability. There is evidence that if it is used for a long time, it will lead to cancer and genetic variation.

At the same time, it will destroy the essential oil and protein of hair growth, inhibit the healthy growth of hair and lead to hair loss. In its manufacturing process, a carcinogen named "1 4 dioxane" will be produced as a by-product through "ethoxylation".

2. diethanolamine (DEA) and triethanolamine (TEA)

Danger: dry+fragile+inanimate

Products containing diethanolamine or triethanolamine can cause scalp inflammation, even allergic reactions, and also affect healthy components (such as keratin) in hair, so why hair is dry, fragile and lifeless is this reason.

3. Sodium chloride

Hazard: hair loss+dryness+itching

Sodium chloride is a widely existing component in salt, and it is also used as a thickener for shampoo and conditioner containing sodium dodecyl sulfate. In addition to hair loss, sodium chloride can also cause scalp dryness and itching. If you do keratin care, you should avoid using sodium chloride, because it will speed up the process of nursing failure.

4. P-hydroxybenzoate

Hazard: skin irritation+hormonal imbalance+hair loss.

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.

5. Formaldehyde

Hazard: hair loss+potential carcinogen

Some shampoos contain formaldehyde, and excessive exposure to formaldehyde may lead to hair loss, which is also a well-known potential carcinogen.
