This is generally not a function of shampoo. Its task is to wash off dust and fat, and at least it's strange to believe advertising and, using just one shampoo a couple of times a week, to wait for them to transform and turn into the hair of your dreams.
And it's okay they were just useless. But in pursuit of a cheaper production, components in the shampoo include the cheapest aggressive substances and preservatives. Someone believes that the toxic components of shampoo can penetrate the skin into the body, accumulate and cause disease, someone - no. Although the alarm in this regard is being beaten by independent and respected sources. For example, Dr. Epstein's Anti-Cancer Coalition.
To memorize by heart all the possible components that make up the shampoo for the hair, an unprepared person is simply impossible. In this article, the goal is to consider the main groups of components in the shampoo and determine which of them are dangerous and which are not.
What is Included in the Shampoo?Washing based:- Based on their main function of cleaning shampoo, the main component of the harmful composition of most popular shampoos are surfactants (surfactants), foaming shampoo base, which produces a detergent effect.
In most shampoos, they are Ammonium Lauryl Sulfate, Ammonium Laureth Sulfate, Sodium Lauryl Sulfate, Sodium Laureth Sulfate, TEA Layril Sulfate, TEA Laureth Sulfate - they give a whole foam cap when soaping.
All of them are usually called one word SLS, being the cheapest and most aggressive substances in the composition of shampoos, as well as corrosive agents. And although TEA (TEA Layril Sulfate, TEA Laureth Sulfate) and DEA (Cocomide DEA, Lauramide DEA) are considered softer surfactants, their toxicity is also proven 15 years ago.
SLS are also part of toothpastes and car washing agents, and along with propylene glycol they have the ability to penetrate the body, carry heavy metals that are trapped in the blood while on the street, accumulate, form carcinogens and cause chronic poisoning and disease.
The harm of shampoo for hair is primarily due to the content of SLS. The application of SLS-containing products to the skin "causes microscopic destruction of the molecular structures of the scalp, which causes increased absorption of other toxic and carcinogenic substances by the skin" (quotation from the conclusion of the study).
The softer detergent components of shampoos are Sodium Oleth Sulfate, 1,2-Dioxane, MEA (Monoethanolamine), Lauric Acid, Sodium C12-13 Pareth Sulfate, Lauryl Polyglucose, Sodium PCA, Disodium Laureth Sulfosuccinate and many others, all not listed, but also they in one way or another negatively affect hair and health in general, whether forming carcinogens or irritating the scalp.
The only components that I could find only positive information are Cocamidopropyl Betaine, Decyl Glucoside and the best reviews from Magnesium Laureth Sulfate.
It is better to buy organic instead of popular shampoos. In the composition of organic shampoos, foam is created by such components as saponins. Usually organic shampoos will foam much worse, since they do not have SLS, and do not wash the hair so well. Look for words like "soap base", "potassium soap base".
In Ayurvedic shampoos, this function is performed by soap nuts, shikakai, and it thoroughly cleanses the hair.
Thickeners also takes a significant share in the composition of hair shampoos, they make the shampoo thick, as we are used to. Cocamide DEA (foam stabilizer), cocamide MEA (a mixture of coconut oil and ethanolamine), linoleamide DEA, PEG 4 monoethanolamide of rapeseed oil, tridecet 2 Carboxamide MEA. I did not find any information about their harm or harmlessness, but the names already seem suspicious to me
Preservatives, thanks to which shampoos do not deteriorate for years. First of all, these are parabens: methylparaben (E218), ethylparaben (E214), propylparaben (E216) and butylparaben. Parabens are the second component of the harmful composition of shampoo. They destroy the enzymes of the skin and accumulate in the body.
Studies have shown that parabens are hormone-like substances, they are referred to as weak estrogens (female hormones). They affect the hormonal background in the body after application to the skin, resulting in lower testosterone levels in boys. And for women, parabens are dangerous primarily because they concentrate in the chest area, causing the formation of cancer cells in this area - this relationship is proven.
Of the other preservatives, DMDM-hydantoin (which has a broad antibacterial effect, and it is doubtful how it affects the skin's microflora), benzoic acid, diazolidinylurea, methylisothiazolinol, phenoxyethanol can be found in the shampoo.
Conditioners. Usually, these are silicones:- Silicones are the popular ingredients that make up the shampoo - they instantly make the hair smooth and shiny due to the smoothing of the scales and the alignment of the damaged areas of the hair, as it envelops the hair with a film.
Silicones can be detected under the names Dimethicone, PEG-12 Dimethicone, Cyclomethicone, Amodimethicone, Phenyltrimethicone, Aminopropyl Dimethicone, Amino Functional Silicones, Dimethicone Copolyol, Trirnethylsilyamodimethicone, or calculate by end -ane, -one, -thiconol, -thiconol, -silane .
What is bad about silicones? Silicones give only a cosmetic effect and use them is only on occasion. Not all silicones are washed off well, some are better, others are worse. This is one of those components that cause damage to hair shampoo.
With constant use, they accumulate on the hair more and more, weighting the hair, making them dirty in appearance.
According to trichologists, silicones are able to penetrate into the hair and accumulate there, making the hair even heavier. And this is already fraught with the fact that long and heavy hair begins to fall out .
You can find information that large molecules of silicones can not penetrate through the scales of the hair. That one, that another point of view can be someone profitable and advance in the media, but the fact remains - with long-term constant use of silicones, hair lose both appearance and health.
If you feel that you are overdone with silicones, you can help special professional shampoos for deep cleaning.
Other ingredients in the shampoo:- In different shampoos there is a very different combination of ingredients. For example, components that protect against ultraviolet and high temperature, perfume fragrance, dyes, allantoin (anti-inflammatory drug), medicinal components ( in dandruff shampoos, for example).
If you find mineral oil (product of oil refining) and formaldehyde in the shampoo (or bronopol is a poison), keep this shampoo away from yourself and your family.
Natural ingredients:- These are the components that are most often loudly declared, but in fact they are on the list of ingredients in the last place and have practically no effect compared to the rest of the mass of chemistry that is part of the shampoo.
It can be herbs, based on herbs prepared shampoo, vegetable oils that nourish the scalp and soften hair, clay, menthol, vitamins, honey and many other delights of the rich imagination of producers. Silk protein, silk amino acids, hydrolyzed wheat protein have a remarkable effect.
Using organic or professional shampoos, you may be surprised by the lack of color and smell, a more fluid consistency and low foaming, but this only speaks in favor of such a shampoo - hence, it contains many dangerous components.
You can also replace ordinary shampoos with homemade ones , that is, cook yourself from natural and inexpensive ingredients. Balms can also be made by yourself, for conditioning and shine hair rinse them after washing with cool water with lemon juice, and the effect of silicones and thermal protection will give you Pantenol.
