Based on its formula, is this shampoo safe for sensitive or dry hair?

The product is dermatologist‑tested and free of silicones and parabens, which helps reduce buildup, but it contains Sodium Laureth Sulfate and fragrance, ingredients that can be drying or irritating for very sensitive scalps, so those users may prefer a sulfate‑free alternative.

What is the role of Niacinamide in this shampoo and how does it benefit colored hair?

Niacinamide (vitamin B3) helps improve the hair cuticle’s integrity, enhances moisture retention and adds shine, which can prolong the vibrancy of dyed hair by reducing fade.

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

For most users, the shampoo can be applied 2–3 times per week to maintain color and shine; it does contain potentially controversial ingredients such as Sodium Laureth Sulfate, fragrance and the preservative methylisothiazolinone, which some consumers choose to avoid.

Product Insights

Shampooing couleur brillance is a 500 ml pharmacy‑grade shampoo formulated specifically for colored hair, aiming to enhance shine while protecting the dye. The formula combines gentle surfactants such as Cocamidopropyl Betaine and Decyl Glucoside with color‑preserving actives like Niacinamide and a UV filter, and it is marketed as dermatologist‑tested, paraben‑free and silicone‑free. However, it still contains Sodium Laureth Sulfate, fragrance and several preservatives including Methylisothiazolinone, which may irritate very sensitive scalps.

Comparative Analysis

Positioned as an affordable, pharmacy‑sourced shampoo for color‑treated hair, its silicone‑free, paraben‑free claim and inclusion of Niacinamide differentiate it from generic shampoos, though it relies on traditional sulfates and fragrance typical of budget hair‑care products.
