OI Shampoo is a sulfate-free daily cleanser built around Roucou oil (Bixa Orellana), a beta-carotene-rich extract from the Amazonian achiote plant, along with Ellagic Acid, which contributes antioxidant properties. The formula uses gentle sulfate-free surfactants — Sodium Lauroyl Methyl Isethionate, Disodium Laureth Sulfosuccinate, and Cocamidopropyl Betaine — to cleanse without stripping.
The Roucou oil deposits a protective lipid layer on the hair fiber during the wash itself, smoothing the cuticle and beginning frizz control and shine enhancement before any conditioner or leave-in is applied. Amodimethicone and Guar Hydroxypropyltrimonium Chloride add further conditioning and detangling during the cleanse.
Suitable for all hair types and everyday use, OI Shampoo is formulated without sulfates or parabens.
