OUAI Fine Hair Shampoo is a lightweight, biotin-enriched thickening shampoo formulated to add volume, strengthen fragile strands, and cleanse without stripping color-treated hair.
Designed specifically for flat, thin hair, this sulfate-free, refill-sized shampoo uses biotin, hydrolyzed keratin, and chia seed oil to gently build body while maintaining a soft, manageable finish. The formula is free of sulfates, parabens, phthalates, and gluten, making it suitable for chemically-treated and color-treated hair that needs lift without heavy residue. The fragrance leans fresh and sophisticated—Mercer Street—so your wash routine leaves hair smelling like Italian lemon, iris, and white musk.
The shampoo targets the hair fiber with ingredients that thicken and lift at the root while delivering a gentle cleanse that won’t weigh hair down. Biotin helps support strand resilience, and chia seed oil adds slip and body so hair feels fuller after rinsing.
Yes — the formulation is color-safe and free of harsh sulfates that can fade dyes more quickly. It is also compatible with keratin treatments and other chemical services, helping preserve tone and surface integrity while improving body.
Apply a quarter- to palm-sized amount to wet hair, focusing on the scalp and roots, then work through to the ends to distribute the active ingredients. Rinse thoroughly, and follow with OUAI Fine Conditioner and optionally OUAI Thickening Spray for amplified lift and sustained shape.
The Mercer Street fragrance blends citrus, floral, and musk for an elevated daily routine that smells fresh without overpowering. The 32 oz refill size reduces waste and keeps a generous supply on hand for frequent washing or multi-person households.
Who is this for: OUAI Fine Hair Shampoo is aimed at people with fine, limp, or thinning-looking hair who want a lightweight, color-safe option to increase body and reduce breakage. It works well for anyone seeking a gentle everyday cleanser that adds lift—suitable for both women and men, and for those who have color, keratin, or other chemical treatments. If you prefer non-heavy, fragrance-forward products and value refill packaging, this formula is designed to fit into that routine.
