Is the Shampoing extra doux suitable for sensitive or acne-prone scalps?

The formula includes both mild surfactants (Decyl Glucoside, Cocamidopropyl Betaine) and potentially irritating ingredients (Sodium Laureth Sulfate, fragrance); it is generally gentle for normal hair but may cause irritation for very sensitive or acne-prone scalps, so a patch test is recommended.

What role does Decyl Glucoside play in this shampoo?

Decyl Glucoside is a plant-derived, non-ionic surfactant that provides gentle cleansing while preserving the natural moisture balance of the scalp and hair, helping the product achieve its "extra gentle" claim.

How often should this shampoo be used, and does it contain any controversial chemicals?

It can be used daily or every other day for regular hair, but it contains Sodium Laureth Sulfate, PEG-based compounds and fragrance, which some consumers consider controversial due to potential irritation or environmental concerns.

Product Insights

The Shampoing extra doux from Cosmia is a 75 ml daily-use shampoo marketed as an extra gentle, eco-friendly formula. It combines mild surfactants such as Decyl Glucoside and Cocamidopropyl Betaine with moisturising glycerin, delivering a soft, clean feel for normal to slightly dry hair. However, the presence of Sodium Laureth Sulfate, fragrance and several PEG-based agents means the product may irritate very sensitive scalps or those avoiding sulfates and synthetic polymers.

Comparative Analysis

Positioned as an ultra-gentle, daily-use shampoo within the eco-friendly "green dot" segment, it differentiates itself by blending mild plant-based surfactants with a light fragrance, yet its inclusion of Sodium Laureth Sulfate and PEG polymers may limit appeal to consumers seeking fully sulfate-free or preservative-free options.
