Yes! All OUAI products are extension-safe for human hair, synthetic, combination extensions, and wigs. This also includes color-treated alternative hair. We always recommend consulting with your hair dresser for the best application tips tailored to your hair care routine and testing any new product on a few strands before usage on a full set of extensions or wigs for precautionary preferences.
OUAI products are always free of sulfates, parabens, and phthalates.
