Product details

OUAI Thick Hair Mask is an intensive deep-conditioning treatment formulated with almond and olive oils plus hydrolyzed keratin to restore moisture, reduce breakage, and smooth damaged strands after one use.

This rich hair mask from OUAI targets dryness, split ends, and frizz without weighing hair down. Designed for all textures — from straight to coily — it blends nourishing butters and a trio of oils to replenish lipids, while hydrolyzed keratin helps strengthen the hair’s inner structure. Free from phthalates and parabens, the formula is built to improve manageability and shine while fitting easily into a weekly hair-care routine.

How does this mask repair split ends and breakage?

The mask combines conditioning butters with strengthening proteins so hair looks and feels healthier. Hydrolyzed keratin penetrates the hair shaft to reinforce weak spots while emollients smooth the cuticle to reduce immediate breakage and split-end appearance.

  • Hydrolyzed keratin helps rebuild tensile strength in damaged fibers
  • Ilipe and shea butters provide long-lasting moisture to brittle ends
  • Almond, olive, and macadamia oils add slip for easier detangling
  • Regular use increases resistance to everyday mechanical damage

Will this weigh down fine hair or make thick hair greasy?

OUAI formulated the mask to deliver concentrated hydration without leaving a heavy residue when used as directed. Fine hair benefits from sparing application focused on mid-lengths and ends, while thicker textures can use more generously for deeper conditioning.

  • Apply quarter-size or less on fine hair, avoiding roots
  • Thicker or very dry hair can use more product for full coverage
  • Rinse with cool water to seal the cuticle and reduce limpness
  • Use weekly or as-needed to maintain balance between moisture and volume

How do I use this mask for best results?

For optimal repair, start with freshly washed, towel-damp hair. Squeeze excess water, distribute a small amount from ends toward roots, wait five minutes, then rinse well to lock in hydration and shine.

  • Squeeze excess water from hair after shampooing
  • Work a quarter-size amount through the mid-lengths and ends
  • Leave on for about five minutes; extend for deeper conditioning
  • Rinse with cool water to close the hair cuticle and enhance gloss

What ingredients make this a restorative treatment?

This mask blends high-emollient butters with a trio of oils and hydrolyzed protein to address both surface smoothness and internal fiber strength. The result is improved manageability, reduced frizz, and enhanced shine without harsh additives.

  • Ilipe and shea butters for moisturization and softness
  • Almond, olive, and macadamia oils for smoothing and gloss
  • Hydrolyzed keratin to help reinforce hair structure and prevent breakage
  • Formulated without phthalates or parabens for a cleaner routine

Who is this for: OUAI Thick Hair Mask suits anyone aiming to repair visible damage and improve hair resilience — especially those with dry, chemically treated, heat-styled, or naturally coarse hair. If you want a quick, salon-level conditioning step that reduces tangles, tamps down frizz, and enhances shine, incorporate this mask into a weekly regimen. People with finer hair can still benefit by using smaller amounts and avoiding the scalp; thicker or more damaged hair will see the most dramatic improvements with regular use.

FAQ

Q: How often should I use the OUAI Thick Hair Mask?

A: Use once weekly for maintenance or 1–2 times weekly for very damaged hair; adjust based on hair’s moisture needs.

Q: Can I leave the mask on overnight?

A: You can extend time for deeper conditioning, but a 5–20 minute leave-in is typically sufficient; use a shower cap if overnight.
