Chelating clarifier clears hard-water buildup and oil; pricey, minimal conditioning.

A bond-focused clarifying shampoo with Bis-Aminopropyl Diglycol Dimaleate, amino acids, and chelating agents for hard-water residue, oil, and buildup. Fine, oily, or frequently styled hair gets the cleanest payoff; dry hair may need a mask afterward.
