Product Insights
The Kérastase Bain Décalcifiant Réparateur is a 250 ml salon‑grade shampoo formulated to eliminate mineral deposits and restore weakened hair fibers. Its formula combines a gentle descaling complex, such as citric acid, with nourishing agents like hydrolyzed proteins and moisturizing oils that help smooth and strengthen the hair shaft. While effective at improving texture, the presence of strong acids and typical surfactants may cause irritation for very sensitive scalps, so a patch test is advisable before regular use.
Comparative Analysis
Positioned as a high‑performance descaling repair shampoo, it targets consumers with hard‑water buildup seeking salon‑level restoration, differentiating itself from regular moisturising shampoos by combining mineral‑clearing action with protein‑based strengthening.
