Summary

Herbal Essences Bio:Renew Argan Oil of Morocco Repairing Shampoo scores 20/100 -- a conventional drugstore shampoo with a 'paraben-free' marketing claim that is technically true but irrelevant. The cleansing base is Sodium Lauryl Sulfate paired with two silicones (Dimethicone + Dimethiconol) for the buildup-then-strip cycle. TEA-Dodecylbenzenesulfonate is a triethanolamine surfactant with N-nitrosamine contamination risk. Undisclosed Fragrance with 5 itemized fragrance allergens (Benzyl Benzoate, Hexyl Cinnamal, Limonene, Alpha-Isomethyl Ionone, Coumarin). Trideceth-10 carries 1,4-dioxane contamination risk from ethoxylation. Tetrasodium EDTA chelator. The genuine plant-oil payload -- Camellia Oleifera Seed Oil, Aloe Vera, Argan Oil -- plus Histidine and Sodium Benzoate as the sole preservative (no MCI/MIT, no phenoxyethanol in the US version) lifts the score above Pantene Classic Clean (15) and Elvive Shampoo (12). Owned by Procter & Gamble.
