OUAI Thick Hair Conditioner Refill 32 oz – Moisturizing, Frizz-Control with Keratin & Shea Butter

OUAI Thick Hair Conditioner Refill is a rich, hydrating conditioner designed to detangle, smooth frizz, and strengthen thick or coarse hair with marshmallow root, hydrolyzed keratin, shea butter, and avocado oil.

This 32 oz refill offers a salon-grade moisturizing treatment formulated specifically for thick, dry, or frizz-prone hair. Free of parabens, phthalates, and sulfates, the formula focuses on slip, hydration, and strand reinforcement so hair is easier to comb, less prone to breakage, and softer after rinsing. The refill format reduces plastic waste while delivering the same concentrated benefits as OUAI’s original Thick Conditioner.

How does this conditioner help detangle and control frizz?

The formula combines marshmallow root for immediate slip with shea butter and avocado oil that smooth the hair cuticle and lock in moisture. Hydrolyzed keratin helps fill weak spots along the strand, reducing flyaways and improving manageability. Together these ingredients make combing wet hair easier and reduce friction-related damage during styling.

• Marshmallow root: enhances slip for faster detangling
• Shea butter: deeply hydrates and seals moisture
• Avocado oil: coats and strengthens strands to prevent breakage
• Hydrolyzed keratin: minimizes frizz and reinforces weakened hair

Will this refill work with thick, coarse, or chemically treated hair?

Yes—this conditioner was developed with thicker textures in mind and performs well on coarse or color-treated hair. Its concentrated moisture content helps restore softness without weighing hair down when used as directed. For chemically-treated hair, it supports elasticity and improves comb-through after shampooing.

• Concentrated hydration suited for dense hair types
• Safe for color-treated hair when used according to networked care routines
• Helps reduce mechanical damage by improving manageability

How should I use the 32 oz refill for best results?

Apply on clean, wet hair from mid-lengths to ends after shampoo. Work through with fingers or a wide-tooth comb, leave on a minute or two for deeper absorption if desired, then rinse thoroughly. Pair with OUAI Thick Shampoo for a full routine tailored to coarse, frizzy, or very dry hair.

• Apply to wet hair, midshaft to ends
• Comb through for even distribution and detangling
• Leave 1–3 minutes for added hydration, then rinse
• Refill pouch reduces single-use plastic and refills original OUAI bottle

What ingredients should I expect and what’s left out?
