Hair treatments target a specific problem rather than daily washing: shedding, dandruff, damage after colour or heat, and early greys. This page holds formulas from L'Oréal, Vichy, Byphasse and Karseell, across medicated shampoos, keratin sprays, smoothing treatments with collagen and biotin, and temporary root touch-up sprays. The practical rule is to choose by cause: anti-dandruff formulas act on scalp yeast, anti-shedding formulas on circulation and the follicle, and repair formulas on the hair shaft itself. Leave a treatment on for the full stated time, because contact time is part of how it works. Everything here is 100% authentic, with delivery to all wilayas and cash on delivery.
