Recently, a lot of little sisters have been madly sending private messages in the backstage: "Miss you, you said a lot of skin care products, but this bald girl wants to know the metaphysics of shampoo? Can you arrange it?"

OK! A hundred causes will have results, your sweet and sweet is me! Today, I will arrange this pure, shampoo and dry goods article for everyone, let you learn to distinguish shampoo in minutes, and stay away from the Mediterranean!

01What exactly does a bottle of shampoo contain?

Shampoos are generally composed of surfactants, conditioners, thickeners, pH regulators, preservatives, flavors and conceptual effects.

Although it is difficult for shampoos to have extremely high added value like essences and creams in personal care products, sometimes the price is not as good as open-shelf facial cleansers...

But shampoo does not mean that there is no scientific and technological content. It is easier to make a bottle of shampoo that is really missing than to make an essence. After all, there is not much difference in the effort they put in design considerations.

02What are the most important ingredients?

NO.1 Surfactant

The most important thing about a bottle of shampoo is, of course, the cleansing ingredients, which is what we call surfactants. The amount, type, and cleverness of the surface activity directly determine the detergency of the shampoo, the dryness of the hair after washing, the comfort of the scalp, and even the cost of the shampoo. For ordinary users, what should they look at when paying attention to the performance of shampoo?

1. The surface activity of amino acids is the mainstream

Generally, amino acid-based anionic surfactants are combined with zwitterionic or non-ionic surfactants on the market. This has the advantage of no toxic and side effects on the scalp, and the cost is relatively easy to control (although the main amino acid-based shampoos are not cheap ). Of course, if you don’t understand amino acid activity, that’s okay. Click here to get a clear understanding of the role of amino acid activity~

2. Zwitterionic & non-ionic more advanced

Amphoteric surface active CAB cocamidopropyl betaine and imidazoline have gradually increased in the personal care market in recent years, and they are both very good mild surface actives. However, at present, CAB is mainly an auxiliary surface activity. In view of cost, manufacturers generally do not add a large amount of it as the main surface activity. The big reason is that if the CAB surface activity is added too much, the frost resistance of the shampoo will become worse. Going to the north may cause precipitation problems.

In addition, some high-end shampoos are used, such as non-ionic surfactants such as APG. On the one hand, it is indeed gentler and friendly to the scalp. On the other hand, it can make the shampoo foam very dense and elastic, but Correspondingly, its price will be more expensive.


In shampoos, there are almost no products based on cationic surfactants. This is because cationic surfactants have strong bactericidal ability and are more irritating to the scalp. Generally, they are only added to detergent and laundry detergent.

It also uses the selective cleansing ingredients (AMT) independently developed by Shiseido, which can be intelligently selected to cleanse and maintain the best scalp condition, especially suitable for easy hair roots. Oily and flat hair.

NO.2 Conditioning agent

Conditioners also play a very important role in shampoos. What a bottle of shampoo feels when it is used, how it feels after washing, and even whether it is easy to blow dry, etc. depend on the embellishment of the conditioner. Mainstream conditioning agents are mainly composed of four parts: colloids, humectants, excipients, and quaternary ammonium salts.

1. Gum

In fact, on the ingredient list on the back of the shampoo, you often see guar gum, cellulose and the like. Their main function is to thicken and increase the smoothness of the shampoo, and the gum can make cationic skin care agents. Adsorbed to the hair to make the hair care effect more obvious. Therefore, in many refreshing anti-dandruff products, this ingredient will be added as little as possible, and shampoos such as those used to repair perm and dye will work harder in this regard.

2. Moisturizer

There are so many types of this, almost endless. The moisturizers that you can see in cosmetics can basically be found in shampoos. But it doesn't mean that adding more moisturizer is good for your hair. Adding more moisturizer will make the hair not fluffy or even make the hair heavy, which may easily cause the problem of hair loss.

3. Excipients

This ingredient is rarely heard. In fact, its main ingredient is oil, which is generally used in shampoos containing fragrance. The Japanese especially like to add this thing, the purpose is to make the fragrance longer and more explosive, while also having a moisturizing effect, which can smooth the frizz of the hair.

4. Quaternary ammonium salt

This category is more subdivided. Quaternary ammonium salt-7, quaternium ammonium salt-8, quaternary ammonium salt-9, etc. are all its shadow clones, which have a certain thickening ability and can bring some slippery feeling to the hair.
