Is this shampoo suitable for sensitive scalps or dry hair?

The presence of strong surfactants (Sodium Laureth Sulfate) and fragrance allergens makes it potentially irritating for very sensitive scalps, while the conditioning agents and Vitamin E can benefit dry or damaged hair, so tolerance will vary by individual.

What role does Vitamin E play in this shampoo’s formulation?

Vitamin E (Tocopherol) acts as an antioxidant that helps protect hair fibers from oxidative stress and may add a subtle shine, complementing the conditioning polymer to improve overall hair resilience.

How often should the shampoo be used and are there any controversial chemicals to be aware of?

It can be used 2–3 times per week for routine cleansing; users should note the inclusion of Sodium Laureth Sulfate, Quaternium‑80 and fragrance allergens, which are common but sometimes flagged for irritation or sensitization concerns.

Product Insights

Cosmia's 250 ml “Shampoing technique repair” is a repair‑focused hair shampoo manufactured in Spain and stocked at Auchan. Its formula combines strong cleansing surfactants such as Sodium Laureth Sulfate and Cocamidopropyl Betaine with conditioning agents like Guar Hydroxypropyltrimonium Chloride, Glycerin and antioxidant Vitamin E to help smooth and strengthen damaged hair. However, the product also contains fragrance, preservatives (Sodium Benzoate, Potassium Sorbate) and potential irritants such as Quaternium‑80, Limonene, Hexyl Cinnamal and a wheat‑derived gluten source, which may trigger sensitivity in some users.

Comparative Analysis

Positioned in the mid‑range technical hair‑care sector, this repair shampoo is distinguished by its blend of conditioning polymer and Vitamin E while still relying on a conventional surfactant‑preservative‑fragrance system common to mass‑market formulas.
