OUAI Thick Hair Mask — Deep Conditioning Hair Mask, 8 fl oz, hydrolyzed keratin & nourishing butters

OUAI Thick Hair Mask is a rich, restorative deep-conditioning treatment designed to strengthen, smooth, and hydrate dry or damaged hair after just one use.

Formulated for all textures — straight, wavy, curly, or coiled — this 8 fl oz mask blends nourishing butters and oils with hydrolyzed keratin to improve manageability, reduce frizz, and support healthier-looking strands. It’s crafted to slip into everyday routines: apply to clean, towel-dried hair, leave for five minutes, and rinse for immediate softness and shine without weighing hair down.

How does this mask repair split ends and breakage?

The formula combines hydrolyzed keratin with a restorative mix of ilipe and shea butters plus almond, olive, and macadamia oils to temporarily strengthen the hair shaft and smooth rough cuticles. While it doesn’t permanently fuse split ends, repeated use makes hair feel more resilient and reduces the visible appearance of damage.

• Hydrolyzed keratin helps shore up weakened strands and reduce breakage during styling.
• Ilipe and shea butters deeply hydrate and smooth dry, brittle ends.
• Lightweight oils add slip and shine without heavy buildup.

Will this work on my hair type and texture?

Yes — the mask is formulated to be effective across a wide range of hair textures, from fine straight hair to thick coils. Its balance of nourishing butters and lightweight oils adapts well: it hydrates denser textures while remaining manageable on finer strands when used sparingly.

• Fine hair: use a smaller amount focused on mid-lengths and ends to avoid weighing roots down.
• Wavy to curly hair: apply generously to restore moisture and define texture.
• Coily or very thick hair: longer processing or slightly more product improves detangling and softness.

How do I use the mask for best results?

Start with freshly washed, towel-dried hair. Squeeze excess water, work a quarter-size amount through ends and mid-lengths, and leave for about five minutes before rinsing with cool water to help seal the cuticle. For deeper conditioning, extend leave-in time or apply on dry hair before a heat-free sleep treatment.

• Step 1: Shampoo and gently towel-dry hair.
• Step 2: Apply from ends to roots, focusing on damaged areas.
• Step 3: Leave 5 minutes; rinse with cool water to lock in shine.

Is this product free from unwanted ingredients?

OUAI prioritizes quality formulations by including beneficial botanicals and excluding certain harsh additives commonly avoided by conscious shoppers. The mask focuses on nourishing components while remaining straightforward to integrate into a minimal or elevated hair-care routine.

• Contains functional butters and oils for targeted hydration.
• Formulated to reduce frizz and improve manageability without heavy silicones overload.
• Designed for regular use as part of a sustainable self-care rhythm.

Who is this for: The OUAI Thick Hair Mask suits anyone looking to repair visual damage, boost softness, and simplify styling — from those with chemically treated or heat-styled strands to naturally dry textures seeking extra moisture. Use it as an occasional intensive treatment or as a weekly staple to maintain smoother, stronger-looking hair with less frizz and more shine.
