If it was not possible to find the right care for yourself, the hair still looks dull, falls out, then you should contact a trichologist (a doctor who diagnoses and treats diseases of the hair and scalp).


Currently, there is a fairly wide variety of shampoos on store shelves: strengthening, restoring, for volume, against dandruff, etc., and the number of brands producing these products is even greater. Accordingly, when choosing your shampoo, your eyes run up, especially not knowing what components a good shampoo should consist of. When choosing a shampoo, you need to take into account your hair type and understand that its main task is to cleanse the hair and scalp from dust and sebum, it is not effective in the fight against split ends, for this it is better to use a mask.

Now we will try to figure out which components should be avoided when choosing a shampoo, and which ones will not harm, and may even be useful.

Shampoo consists of 2 main components: water and surfactants (surfactants), due to which the foam is formed. These components account for 50-80% of the composition, and the remaining 20-50% fall on various additives: preservatives, dyes, fragrances, thickeners, silicones, etc. Therefore, when choosing a shampoo, you need to pay attention not to the label, but to the composition.

Hair shampoo composition

When viewing the squad, special attention should be paid to the first 5 positions, because it is these ingredients that will be in the shampoo in large quantities, and, in principle, in any product.

Hazardous components

Hazardous Shampoo Ingredients

The most commonly used surfactants in shampoos are Sodium Lauryl Sulfate (SLS), Sodium Laureth Sulfate (SLES) and Ammonium Lauryl Sulfate. They are responsible for the formation of foam and cleansing the scalp, but these components have a cumulative effect and, especially with frequent use, can cause scalp irritation, dryness, and dandruff. The scalp itches, so the hair quickly becomes greasy and we want to wash it again, a vicious circle.

  • Parabens

They are added to increase the shelf life of the product and may cause an allergic reaction.

  • Cocamides

Used to create the desired shampoo consistency. They can also irritate the scalp and stimulate dandruff and itching.

  • Diethanolamine (Diethanolamine, DEA), Triethanolamine (Triethanolamine, TEA)

These products can help break down the keratin of the hair, making it dry and brittle.

  • Formaldehyde

In large doses, this component can contribute to the weakening of the hair follicle and hair loss. This substance is a strong allergen.

  • Mineral oil

It is not absorbed into the skin by hardening with a film, and accordingly interferes with the breathing of the scalp.

  • PEG (Polyethyleneglycol) – polyethylene glycol

Thickener and stabilizer. May cause metabolic disorders.

Negatively affect the reproductive function of boys.

  • Triclosan
  • Sodium benzonate (benzoic acid)

Shampoo composition

Valid components

Components that clean more gently without causing serious harm.

Soft Pav

  • Sodium Cocoyl isethionate

It is also a mild surfactant

  • Disodium Cocoamphodiacetate

A mild emulsifier responsible for the foaming and thickening of the shampoo.

  • Triethanolamine Lauryl Sulfate (TEA)
  • DEA-Cetyl phosphate
  • DEA Oleth 3 phosphate
  • Cocamide DEA
  • Myristamide dea
  • Lauramide DEA
  • Stearamide MEA
  • Cocamide MEA

Safe components

Safe shampoo ingredients

From a minute contact with hair, they simply will not have time to penetrate to the bulbs and somehow act. Vitamins are best taken orally.

  • Fruit acid

The same as with vitamins.

UV protection. SPF acts at the moment when it is directly on the surface, and there is no point in washing.

The component that makes the hair smooth and shiny. But, silicones have a cumulative effect, and accumulating on the hair, make them heavier.

  • Antioxidants
  • Sodium Lauryl Sarcosinate
  • Sodium Lauryl Sulfoacetate
  • Sodium Cocoyl Glutamate

Softens hair, moisturizes the scalp, has antioxidants.

  • Disodium Laureth Sulfosuccinate

Has a stable pH

  • Decyl Polyglucose (polyglucoside)

Includes useful components: glucose, coconut fatty acids.

They have anti-static properties.

These ingredients do not foam as much as aggressive surfactants, but they have beneficial properties and do not disturb the pH of the scalp.


Shampoos with safe components in the composition can also cause scalp irritation, dandruff, itching, since it all depends on the individual tolerance of the components.

You can buy these shampoos in professional and organic cosmetics stores.

If it was not possible to find the right care for yourself, the hair still looks dull, falls out, then you should contact a trichologist (a doctor who diagnoses and treats diseases of the hair and scalp).
