Is this shampoo suitable for sensitive or dry scalp types?

The product’s cleansing agents, especially sodium laureth sulfate, can be drying, and its fragrance blend includes known allergens such as linalool and hexyl cinnamal, so individuals with sensitive or eczema‑prone scalps may experience irritation, although conditioning ingredients like guar hydroxypropyltrimonium chloride and palm oil help mitigate dryness for many users.

What role does Sodium Laureth Sulfate play in this formula?

Sodium Laureth Sulfate acts as the primary surfactant, generating foam and effectively removing oil and residue from the hair, but it can also strip natural lipids, which is why the shampoo includes conditioning agents and moisturizing oils to counterbalance potential dryness.

How often should the shampoo be used, and does it contain any controversial ingredients?

For optimal smoothing results, use the shampoo 2‑3 times per week or as needed; it contains parabens (methylparaben, ethylparaben) and several fragrance allergens, which some consumers consider controversial due to possible irritation, so a patch test is recommended before regular use.

Product Insights

Expert lissage+ shampooing professionnel by Franck Provost is a 750 ml silicone‑free, professional smoothing shampoo designed for hair straightening. Its formulation blends strong cleansing surfactants (sodium laureth sulfate, coco‑betaine) with conditioning agents such as guar hydroxypropyltrimonium chloride and a small dose of palm oil to deliver a sleek, manageable finish. Nevertheless, the product contains several fragrance allergens (linalool, hexyl cinnamal, butylphenyl methylpropional, benzyl alcohol, benzyl salicylate) and parabens (methylparaben, ethylparaben) that may irritate sensitive scalps, and the SLS‑type surfactants can be drying for very dry or damaged hair.

Comparative Analysis

Positioned as a silicone‑free professional smoothing shampoo, it targets salon‑level straightening results and stands out from many competing smoothing shampoos that rely on silicones for slip.
