Turn The Volume All The OUAI Up: Is volume just a button on your phone? This thickening shampoo delivers major bounce and lasting volume with a gentle clean that doesn’t strip. So you can finally be fine with being fine.
Stronger Strands, Less Breakage: Biotin reduces breakage, hydrolyzed keratin smooths and adds shine, and chia seed oil thickens and volumizes without weighing hair down. Apply to roots and work through to ends.
A Clean Formula You Can Feel Good About: Free of sulfates, parabens, phthalates, and gluten. Safe for color-treated, keratin-treated, and chemically-processed hair. No harsh trade-offs for fine hair.
Pair It For Best Results: Follow with OUAI Fine Conditioner to lock in volume without weight. Layer in OUAI Thickening Spray for extra lift. The full routine will have you feeling fine.
OUAI Hair, Body & Fragrance: This thickening, volumizing shampoo is made to transport you wherever you go, with a Mercer Street scent featuring notes of Italian lemon, iris, and white musk.
