OUAI Fine Hair Conditioner — Volumizing Conditioner for Fine Hair, 10 oz, with Keratin & Biotin

OUAI Fine Hair Conditioner is a lightweight, volumizing conditioner formulated with keratin, biotin, and chia seed oil to add softness, bounce, and lift to fine hair without weighing it down.

Designed as the follow-up to OUAI Fine Shampoo, this 10 oz conditioner nourishes fragile strands while creating body and manageability. The formula combines hydrolyzed keratin to smooth cuticles, biotin (vitamin B7) to support stronger-looking hair, and chia seed oil to help impart thickness and shine. Free from parabens, sulfates, and phthalates, it’s made for everyday use when you want fuller-looking hair without heavy residue.

How does this conditioner add volume without weighing hair down?

The lightweight base and targeted actives build body at the mid-lengths and ends rather than coating the scalp. Hydrolyzed keratin smooths and reduces flyaways, while chia seed oil provides a thin layer of conditioning that thickens the appearance of each strand.

• Low-residue emollients preserve natural lift at the roots.
• Hydrolyzed keratin reduces frizz for cleaner volume.
• Chia seed oil conditions without heavy oils.

What key ingredients should I expect and what do they do?

OUAI Fine Hair Conditioner blends three primary actives to target fine hair concerns: biotin, hydrolyzed keratin, and chia seed oil. Each ingredient addresses a different need—strength, smoothness, and visual thickness—so your hair looks fuller and feels softer after rinsing.

• Biotin (Vitamin B7): supports hair resilience and a healthier appearance.
• Hydrolyzed keratin: improves texture, decreases frizz, and enhances manageability.
• Chia seed oil: lightweight conditioning that helps each strand appear thicker.

How should I use it for best results?

Apply after cleansing with a fine-hair shampoo, working a quarter-size amount through mid-lengths and ends. Leave for 1–2 minutes to let the formula penetrate, then rinse thoroughly; style as usual. Pairing with OUAI Fine Shampoo yields the most consistent volume and texture benefits.

• Use on towel-dried hair for even distribution.
• Concentrate on mid-shaft to ends—avoid the scalp for extra lift.
• Rinse well to prevent buildup and maintain lightweight bounce.

Is this conditioner suitable for color-treated or daily use?

The formula is free of parabens, sulfates, and phthalates, making it compatible with many color-treated routines and safe for regular use. Its mild conditioning system is balanced to keep fine hair hydrated without dulling color or weighing strands down.

• Gentle enough for daily or frequent washes.
• Doesn’t contain harsh sulfates that strip color.
• Pairs well with thermal styling and volumizing products.

Who is this for? OUAI Fine Hair Conditioner is ideal for people with naturally fine, limp, or thinning-looking hair who want an easy-to-use conditioner that boosts volume and softness without heavy buildup. It’s suited for those seeking salon-style lift at home, anyone avoiding sulfates and parabens, and users who want quick, reliable results while keeping styling time simple.
