OUAI Thick Hair Shampoo & Conditioner Set — 10 fl oz Each, Sulfate-Free, Hydrating & Frizz-Reducing with Keratin & Shea Butter

OUAI Thick Hair Shampoo and Conditioner Set is a sulfate-free cleansing and moisturizing duo formulated with keratin, shea butter, marshmallow root, and avocado oil to strengthen, tame frizz, and restore bounce to thick, dry hair.

Everyday routines benefit from products that tackle density and dryness without weighing hair down. This OUAI two-piece set—10 fl oz shampoo and 10 fl oz conditioner—was created to hydrate dense strands, smooth rough cuticles, and make styling or air-drying more manageable. The formula is color-safe and free from sulfates, parabens, phthalates, and gluten, offering a salon-quality approach at home while remaining cruelty-free.

How does this set hydrate thick hair without leaving it heavy?

The shampoo uses gentle, sulfate-free cleansing agents that remove buildup without stripping natural oils, while the conditioner deposits moisture-smart emollients that slip through dense hair. Lightweight but rich ingredients like marshmallow root and avocado oil provide hydration and softness without creating residue. Together they balance moisture, so hair feels bouncy rather than weighed down.

• Keratin strengthens strand structure to resist breakage.
• Shea butter seals in moisture and softens coarse ends.
• Marshmallow root improves slip for easier detangling.
• Avocado oil adds lightweight nourishment and shine.

Will this shampoo and conditioner reduce frizz and make styling easier?

Yes—the combination of smoothing agents and hydrators helps tame frizz by evening out the cuticle and reducing flyaways. The set prepares hair for styling by creating a more uniform surface, which makes blow-drying, straightening, or air-drying produce sleeker results. Expect improved manageability with less time spent battling frizz.

• Smooths rough cuticles for a sleeker finish.
• Softens split ends to reduce visible frizz.
• Improves detangling to minimize mechanical damage during styling.

What performance can you expect on color-treated or damaged hair?

The formula is color-safe and formulated to be gentle on treated hair while addressing common damage like dryness and breakage. Keratin works to strengthen compromised areas, while the hydrating blend restores flexibility and sheen. Regular use helps improve texture and reduces the appearance of damage without accelerating color fade.

• Color-safe surfactants preserve dye vibrancy.
• Keratin and oils reinforce and smooth damaged strands.
• Hydrating ingredients restore elasticity and reduce breakage.

How do I incorporate this duo into my routine for best results?

Use the shampoo to cleanse and remove product buildup, focusing on the scalp, then rinse thoroughly. Apply the conditioner mid-length to ends, leave for one to three minutes, then rinse for lightweight softness or longer for deeper hydration. For maximum benefits, pair with minimal heat styling, regular trims, and occasional deep-conditioning treatments.

• Shampoo: massage into wet scalp, rinse fully.
• Conditioner: apply from mid-shaft to ends, leave 1–3 minutes.
• Finish with cool water to seal the cuticle and enhance shine.

It's suited to anyone seeking to smooth frizz, strengthen strands with keratin, and bring back bounce and manageability to dense hair.
