So that tells us about the experience of ancestors? What did wash the hair with?
Still we can hear people saying that an ordinary soap is best suited for this purpose. Salts of natural fatty acids, are included in it, they do not irritate the skin and are not accumulated in tissues, and washed, if not as effectively as synthetic surfactants, it is still good enough. And in order to neutralize the alkaline, you can use the hair rinse vinegar. By the way, they say sometimes that shampoos "alkalize" hair, violating the structure of keratin.
Soap and vinegar - not the worst of the recommendations, if the goal is very simple and utilitarian, as platoons when bathing in the garrison bath. But when such advice comes from a cosmetologist, whose primary concern is to provide hair beauty and convenience of the customer - it is very sad.
In addition, the soap does not contain ingredients that strengthen hair and improve their appearance, not to mention the comfort while cleaning. In short, if you want to not only remove dirt from the hair, but also make them beautiful, it's better not to use soap and shampoo.
As we have just seen, the ideal cleanser for the hair should remove impurities, but not degrease. This seemingly weird problem today was resolved. High-quality shampoo, washing hair with a fatty layer, immediately replace it with substances which are called overfatting additives. It can be vegetable oils and animal fats, fatty acids and derivatives of lanolin, lecithin. Overfatting additives are suspended in the shampoo in the form of droplets or micelles. Originally anticipated that the introduction of oils in shampoo will reduce the extraction of fat from the hair. But everything turned out more successful: it was found that when they wash with shampoo so there is an exchange of fat between the shampoo and hair surface. Dirty oil is washed and the hair is wetted by coconut oil or jojoba oil sheen.
Vegetable oils and extracts are often included in the composition of high-quality shampoos. But as far as shampoos, "consisting of only natural ingredients," forced to disappoint fans of the "natural" beauty: it is nothing more than advertising. Without modern organic synthesis there can not be created no cleaning agents. True, for the same sodium lauryl sulfate can be used and synthetic alcohols and alcohols from coconut oil. But those and others through the same sequence of chemical transformations on the way to the final product, and it is obvious, "natural" is lost. In the end, does not the fact that Shampoo surfactants from natural plant materials will be better than shampoo surfactants from synthetic raw materials.
