Pureology Strength Cure is a sulfate-free shampoo and conditioner pair built for damaged, color-treated hair. The formulas use Asta-Repair with astaxanthin, plus Keravis, ceramide and arginine, to fortify weakened strands and smooth a rough cuticle. The Antifade Complex aims to keep color vibrant, and the system is vegan. It suits people with bleached, heat-styled or otherwise stressed hair who want repair without stripping color; against drugstore repair duos it trades a higher price for a concentrated, salon-style formula, and reviewers often note it lathers less than sulfate shampoos.
