OUAI Fine to Medium Hair Treatment Mask — 8 oz lightweight deep-conditioning with shea butter & keratin for hydration, frizz contr

OUAI Fine to Medium Hair Treatment Mask is a lightweight deep-conditioning hair mask formulated to hydrate, detangle, and strengthen fine-to-medium strands without weighing them down.

This targeted treatment mask balances potent yet light moisturizers with strengthening proteins so you get visible softness, reduced frizz, and improved manageability without a heavy finish. Designed for hair that needs repair and resilience but not excess weight, the formula blends shea butter, hydrolyzed keratin, and panthenol to restore texture and shine while keeping hair springy and touchable.

How does this mask hydrate without making fine hair limp?

The mask uses lightweight emollients and humectants that deliver moisture into the fiber without coating each strand in heavy oils. Hydration is calibrated so strands stay buoyant and have natural movement after rinsing.

• Uses panthenol for water retention without greasy residue
• Shea butter is balanced in formulation to add slip, not weight
• Rinse with cool water to help seal the cuticle and maintain lift

Will it help with damage and breakage?

Yes—the formula includes hydrolyzed keratin and strengthening agents that temporarily reinforce weakened areas of the hair shaft, making strands less prone to snap during styling. Regular use improves elasticity and reduces the appearance of split ends without heavy buildup.

• Hydrolyzed keratin supports fiber repair and tensile strength
• Panthenol improves flexibility so hair resists mechanical stress
• Lightweight conditioning avoids ingredient accumulation that can mask damage

How should I use this mask for best results?

After shampooing, comb the mask through mid-lengths to ends and leave on for the recommended time to let active ingredients penetrate. Rinse thoroughly with cool or lukewarm water to close the cuticle and enhance shine; pair with an OUAI shampoo for consistent results.

• Apply to towel-dried hair, focusing on mid-lengths and ends
• Comb through with a wide-tooth comb for even distribution
• Rinse with cool water to seal and amplify gloss

Is this product free of common irritants and cruelty-free?

OUAI’s Fine to Medium Hair Treatment Mask is formulated without parabens, phthalates, SLS, or SLES and is cruelty-free. It’s suitable for routine use in color-treated and chemically serviced hair when you want cleaner ingredient choices in your conditioning step.

• Paraben-, phthalate-, SLS- and SLES-free
• Cruelty-free and gluten-free formulation
• Designed to be compatible with color and chemical services

Who is this for: This mask is intended for people with fine to medium hair who want a restorative, non-greasy deep conditioner. It’s ideal if you need targeted repair for damage, frizz control, and moisture without sacrificing bounce or volume—especially if you use styling tools or color treatments regularly.
