OUAI Thick Hair Mask deep-conditioning treatment for thick, dry or damaged hair — 3.4 oz, almond & olive oils, hydrolyzed keratin

OUAI Thick Hair Mask is a rich, deep-conditioning treatment formulated with illipe and shea butters, a trio of nourishing oils, and hydrolyzed keratin to restore moisture, reduce breakage, and smooth thick hair in minutes.

This intensive masque targets thick, dry, or damaged hair with a concentrated blend of emollients and proteins designed to replenish lost moisture, tame frizz, and improve manageability. Lightweight enough to rinse out after a quick five-minute treatment yet substantial enough for overnight use, the formula balances slip for detangling with protein to help strengthen hair fibers. OUAI packs this 3.4-ounce tub with plant-derived butters, almond, olive, and macadamia oils, plus hydrolyzed keratin, and keeps the product free from parabens, phthalates, SLS/SLES, and gluten.

How quickly will I notice softer, shinier hair?

Many users experience smoother hair after the first rinse thanks to the high concentration of butters and oils that condition the cuticle. Hydrolyzed keratin helps reduce the appearance of split ends and adds a surface-strengthening effect that reflects light better, so shine improves fast.

• Visible softness after one five-minute treatment
• Improved shine from cuticle-smoothing oils
• Reduced frizz and easier detangling

Can this masque actually repair damage without weighing thick hair down?

The formulation pairs rich butters with a blend of lighter oils and hydrolyzed keratin to deliver moisture and protein without leaving hair greasy. Applied primarily to mid-lengths and ends, it targets compromised areas and preserves body at the roots when used as directed.

• Illipe and shea butters for deep conditioning
• Almond, olive, and macadamia oils for softness and slip
• Hydrolyzed keratin to improve tensile strength and reduce breakage

Is overnight use safe and effective for thick or curly hair?

Yes — OUAI recommends a damp, clean base and light distribution for overnight treatments. Leaving the masque on gives the ingredients extended time to penetrate and condition, especially for very dry or chemically treated hair. Rinse thoroughly in the morning and shampoo the scalp if needed.

• Apply to damp, product-free hair for overnight use
• Distribute with a wide-tooth comb and secure hair in a bun or bonnet
• Rinse and shampoo scalp in the morning if product buildup occurs

How should I use this mask in my regular routine?

Use the mask as a weekly intensive treatment or more often when hair needs extra repair and moisture. For a quick boost, apply after shampooing, leave for five minutes, then rinse with cool water; for deeper repair, follow the overnight instructions. Adjust frequency based on hair porosity, styling habits, and exposure to heat or chemical services.

• Weekly five-minute treatment for maintenance and shine
• Overnight application for deeper conditioning and repair
• Use more frequently on color-treated or highly textured hair
