OUAI Thick Hair Conditioner Refill 32 oz — Moisturizing, Keratin & Shea Butter for Dry, Frizzy Thick Hair

OUAI Thick Hair Conditioner Refill is a rich, salon-quality moisturizer formulated to detangle, reduce frizz, and strengthen thick, dry hair with keratin, marshmallow root, shea butter, and avocado oil.

This refill-sized conditioner delivers concentrated hydration for thicker hair textures that need extra slip and nourishment. The formula combines conditioning botanicals and proteins to smooth the cuticle, improve manageability, and help prevent breakage while keeping styling time practical. Packaged as a 32 oz refill, it’s designed to reduce waste and keep your go-to conditioner on hand for longer between purchases.

How does this conditioner make thick hair easier to manage?

The blend focuses on slip and detangling so you can work through knots with less pulling. Marshmallow root and rich emollients soften the hair surface, while avocado oil and shea butter lock in moisture for improved elasticity and fewer breakages.

• Marshmallow root eases comb-through and reduces tangling.
• Shea butter provides sustained hydration and softness.
• Avocado oil coats and reinforces strands to lower breakage risk.
• Hydrolyzed keratin helps control frizz and smooth flyaways.

Will this help dry or frizzy hair without weighing it down?

Although luxuriously creamy, the formula balances rich moisturizers with proteins to avoid a greasy finish on thicker hair types. Applied from mid-lengths to ends, it restores hydration where hair needs it most while keeping root area lightweight when used as directed.

• Apply from midshaft to ends to prevent overloading roots.
• Rinse thoroughly for softness without residue.
• Sulfate-, paraben- and phthalate-free formulation for cleaner-feeling hair.
• Designed to pair with OUAI Thick Shampoo for best results.

How should I use the 32 oz refill to get the best value and performance?

The refill lets you replenish your regular bottle or decant into smaller travel containers. Use with damp hair after shampooing: distribute evenly, finger-comb or use a wide-tooth comb, let sit briefly if extra smoothing is desired, then rinse.

• Refill into your existing OUAI pump bottle to reduce plastic waste.
• For intense hydration, leave in for 1–3 minutes before rinsing.
• Use regularly with OUAI Thick Shampoo for consistent results.
• Store upright in a cool, dry place to maintain formula integrity.

Is this product formulated with any harsh ingredients I should avoid?

The product omits sulfates, parabens, and phthalates and focuses on actives that smooth and hydrate. That said, if you have specific sensitivities, check the full ingredient list to confirm compatibility with your scalp or treatments.

• No added sulfates, parabens, or phthalates in the formula.
• Contains hydrolyzed keratin and natural oils—avoid if you react to proteins or botanicals.
• Safe for regular use as part of a thicker-hair routine when used as directed.
