OUAI Fine to Medium Hair Treatment Masque — 3.4 oz Lightweight Repair Mask with Shea Butter & Hydrolyzed Keratin for Hydration and

This 3.4 oz treatment masque is formulated specifically for fine to medium hair that needs moisture and repair without heaviness. The lightweight formula restores softness and shine while helping to reduce breakage and tame frizz. Free from parabens, phthalates, sulfates (SLS/SLES), and gluten, this cruelty-free masque uses targeted actives to refresh dry, damaged hair without weighing it down.

How does this masque hydrate hair without making fine strands limp?

The formula balances rich emollients with lightweight humectants so moisture gets in without coating hair in heavy oils. Shea butter conditions and seals hydration while panthenol draws in and locks moisture, leaving hair supple but bouncy. Hydrolyzed keratin adds structural support so strands feel stronger, not flattened.

• Shea butter for focused conditioning at ends
• Panthenol (pro-vitamin B5) for moisture retention and shine
• Hydrolyzed keratin to reinforce and reduce breakage
• Sulfate- and paraben-free base avoids stripping and buildup

When and how should I use the OUAI treatment masque for best results?

Use the masque after shampooing on freshly cleansed, towel-squeezed hair. Smooth a quarter-size amount from mid-lengths to ends, wait about five minutes, then rinse with cool water to seal the cuticle and lock in shine. For extra damage control, apply once weekly or more often on particularly dry or chemically treated hair.

• Squeeze excess water before applying to ensure even absorption
• Focus product on split-prone ends and mid-lengths
• Five-minute processing time for an in-shower deep treatment
• Finish with cool rinse to enhance gloss and seal moisture

Will this masque help with frizz and styling longevity?

Yes—by smoothing the hair cuticle and rebuilding weakened fibers, the masque reduces frizz and helps styles hold longer. The conditioning blend softens texture so daily styling tools glide more easily, decreasing mechanical damage. You’ll notice improved manageability and a smoother finish after a few uses.

• Keratin supports strand integrity to reduce future frizz
• Softening agents cut down on tangles for easier comb-throughs
• Lightweight formulation avoids weighing hair down between washes

Who this product is for: If you have fine to medium hair that’s become dry, brittle, or frizz-prone—whether from heat styling, coloring, or environmental stress—this masque provides targeted hydration and strengthening without heaviness. It’s ideal for anyone seeking a quick in-shower repair treatment that leaves hair softer, shinier, and more resilient. OUAI’s Melrose Place fragrance layers a subtle rose, bergamot, and musk scent for a polished finish, and the recyclable packaging supports eco-conscious routines.
