How to determine the quality of the shampoo according to its chemical composition?

The next parameter of selection of shampoo is the quality of its chemical components, a list of which, incidentally, must be listed on the bottle, otherwise it is not worth buying. Of course, the chemical formula of the shampoo say nothing to ordinary people, but there is a sign by which you will always be able to assess the quality of any shampoo.

The fact that the main active ingredient of each shampoo is a detergent – a surface-active agent (surfactant), which, when mixed with water and air leads to the cleaning foam. Most of shampoos use one or several of the six major detergents, which we list in descending order of quality:

1.ТЕА Laureth Sulfate;
2. TEA Layril Sulfate;
3. Sodium Laureth Sulfate;
4. Sodium Lauryl Sulfate;
5. Ammonium Laureth Sulfate;
6. Ammonium Lauryl Sulfate.

Unfortunately the majority of shampoos, which are represented on the shelves, use maximum third and fourth quality detergent, and some shampoos, even very advertised – the fifth-sixth ones. You can check it if you want, the name of the detergent in the list of components of the shampoo is indicated one of the first components.

The main disadvantage of the least qualitative and cheapest detergents is their dermatological rigidity – they make your hair dry and brittle, dry and irritate the scalp. Therefore, if washing of your hair with shampoo, you notice that your hair was light and fluffy, you should not be happy – it means that a strong surfactant is used in it that is the shampoo degreases the hair and scalp.

Particularly attentive to the choice of shampoos on the quality of the detergent should be those who have to wash my hair every day – athletes, people with sensitive skin of the head, as well as those who dyes their hair.

You can also orient yourself the fact that a good shampoo is made up of 20-30 chemical ingredients – it is believed that the more of them there, the better. But if you are prone to allergies, it is better to choose a simple composition of shampoo with a small number of components.
