OUAI Fine Hair Volumizing Conditioner Refill 32 oz — Keratin, Biotin & Chia Seed Oil for Lightweight Volume and Softness

OUAI Fine Hair Conditioner Refill (32 oz) is a volumizing, hydrating conditioner formulated with keratin, biotin, and chia seed oil to add softness, bounce, and fuller-looking body to fine hair.

This large refill pouch is designed to restore life to limp strands without weighing them down. The lightweight formula blends hydrolyzed keratin to reduce frizz, biotin (Vitamin B7) to support stronger-looking fibers, and chia seed oil to help create the appearance of thicker, more voluminous hair. Free from sulfates, parabens, and phthalates, it slots easily into a simplified routine after using the OUAI Fine Shampoo.

How does this conditioner build volume without heavy residue?

The formula targets fine hair with ingredients chosen for lift and manageability rather than heavy moisturizing oils that can flatten strands. Hydrolyzed keratin helps smooth the hair cuticle and control flyaways, while chia seed oil and lightweight emollients help thicken and separate each strand for visible body. The result is fuller shape and movement without a greasy finish.

• Hydrolyzed keratin reduces frizz and smooths cuticles for cleaner lift.
• Biotin (Vitamin B7) supports stronger-looking hair structure.
• Chia seed oil adds a weightless thickening effect and sheen.
• Formulated without sulfates, parabens, or phthalates to avoid buildup.

What’s the best way to use the 32 oz refill for consistent results?

Pour the refill into your existing OUAI bottle or a pump dispenser for easier daily use and to reduce single-use plastic. After shampooing, apply a quarter-size amount to mid-lengths and ends, leave in for 1–2 minutes to allow actives to penetrate, then rinse thoroughly. For extra lift, follow with a volumizing styling product at the roots while hair is damp.

• Transfer to a pump bottle to control dispensing and limit waste.
• Focus application on mid-shaft and ends—avoid the scalp to prevent weighing down.
• Leave in briefly before rinsing for optimal absorption.
• Pair with OUAI Fine Shampoo and lightweight styling products for best volume.

Which hair concerns will this conditioner help with most?

It’s aimed at people with fine, limp, or thin-seeming hair who want more body and smoother texture. Expect reduced flyaways, added lift, and a softer feel without heavy moisturization that can collapse volume. While not a treatment for hair loss, the formula’s strengthening and thickening ingredients visibly improve manageability and fullness.

• Adds bounce and visible thickness to fine or flat hair.
• Smooths frizz and improves comb-through ease.
• Maintains lightweight moisture balance for natural movement.
• Suitable for daily use in place of heavier conditioners.

Who is this for? This refill is ideal for anyone with fine or limp hair who wants salon-quality volume at home while reducing packaging waste. It's a practical choice for people who already use OUAI Fine Shampoo or those who prefer refill formats to keep costs and plastic use down. If you want lightweight conditioning, lifted shape, and ingredients focused on strengthening and texture enhancement, this 32 oz refill is designed to deliver consistent, everyday results.
