Top 5 Ingredients in Hair Care Products

In order to help everyone better understand the ingredients and working principles of hair care products, Lin Yunxuan specifically explained the five major ingredients of common hair care products to the public:

1. Organic acid: Because shampoo products are weakly alkaline, hair care products added with organic acid can help the hair and scalp recover to weak acidity after cleaning, so as to adjust the pH.

If the organic acid is used in permed or bleached hair, it can help protein coagulate and avoid protein loss.

Among them, citric acid is the most common.

2. Grease: Grease can make hair shiny. Common ingredients include ceramide, olive oil, almond oil, jojoba oil, fatty acids, fatty alcohols, fatty esters, and beeswax.

3. Vitamins: Vitamin B5 can be used for moisturizing, and vitamin E can help moisturize. Some products use wheat germ oil that contains vitamin E.

4. Protein hydrolyzate and amino acid: protein has a large molecular weight and cannot directly pass through the cuticle. Therefore, to provide hair care effects, protein hydrolyzate or amino acids with smaller molecules will be used.

The common keratin protein hydrolyzate may be extracted from horse hair, wool, cow horn, etc., or silk protein, collagen, etc.; and the more common plant sources are oats, wheat, soybeans, etc.

Hair care products containing silicone ingredients do not actually cause damage to the scalp, and the public does not need to worry too much.
