Is this shampoo suitable for sensitive scalps or people prone to skin irritation?

The shampoo contains sodium laureth sulfate and preservatives methylchloroisothiazolinone and methylisothiazolinone, which are recognized as potential irritants, so it may not be ideal for highly sensitive scalps; those with known sensitivities should consider a milder, sulfate-free alternative.

What is the role of polyquaternium-7 in this shampoo and how does it benefit hair?

Polyquaternium-7 is a conditioning polymer that forms a thin film on hair fibers, reducing static, improving slip and detangling, and leaving the hair feeling softer and smoother after washing.

Does this shampoo contain any controversial chemicals, and should I be concerned about them?

Yes, it includes methylchloroisothiazolinone and methylisothiazolinone (preservatives linked to allergic reactions), benzophenone-3 (a UV filter with endocrine-disrupting concerns), and synthetic dyes CI 15985 and CI 42090, which may raise safety or environmental concerns for some consumers.

Product Insights

Carrefour offers a 500 ml normal-hair shampoo that combines strong cleansing surfactants (sodium laureth sulfate, sodium chloride, cocamidopropyl betaine) with moisturizing glycerin and the conditioning polymer polyquaternium-7, and it carries the Green Point eco-label for its packaging. The formula also features a modest amount of almond seed extract for a botanical touch, fragrance, a UV filter (benzophenone-3) and synthetic colorants (CI 15985, CI 42090) that give it a pleasant scent and bright appearance. However, it contains several known sensitizers such as methylchloroisothiazolinone, methylisothiazolinone, and the potentially irritating surfactant sodium laureth sulfate, and the plastic bottle offsets its eco-label advantage.

Comparative Analysis

Positioned as an affordable everyday shampoo for normal hair, this Carrefour product differentiates itself by pairing a classic surfactant base with conditioning polyquaternium-7 and almond extract while standing out for its Green Point label despite the presence of controversial preservatives and synthetic dyes.
