OUAI Fine Shampoo & Conditioner Set — Sulfate-Free 10 fl oz, Volume-Boosting with Keratin

This two-piece bundle pairs OUAI Fine Shampoo and Fine Conditioner to target limp or delicate hair that needs body and moisture in one easy routine. The shampoo gently removes buildup while supporting strand strength with keratin and biotin, and the conditioner detangles and adds slip using lightweight but nourishing emollients. Together they aim to create fuller-looking hair and smoother styling prep without silicones, parabens, phthalates or harsh sulfates.

How does this set add volume to fine hair?

The formula combines proteins and lightweight oils that lift at the root and strengthen strands so hair holds shape better. It avoids heavy emollients that can flatten fine textures, while still delivering hydration and detangling benefits for easier styling.

• Keratin and biotin help reinforce hair cuticles for fuller appearance.
• Marshmallow root provides natural slip and buoyancy to strands.
• Lightweight chia seed and avocado oils moisturize without weighing hair down.

Will this work for color-treated or chemically processed hair?

The sulfate-free cleansing base is milder than traditional shampoos, making it a compatible choice for many color- or chemically-treated hair types. It cleans and conditions while preserving treated hair's integrity, but always patch-test or consult your stylist for specific treatments.

• Sulfate-free formula helps protect color from accelerated fading.
• Keratin supports strength for chemically processed strands.
• Free of parabens and phthalates to reduce unnecessary additives.

How should I use the shampoo and conditioner for best results?

Start with a small amount of shampoo on wet hair to create a gentle lather and rinse thoroughly; follow with a quarter-sized amount of conditioner focusing on mid-lengths to ends. Rinse with cool water for added shine and use styling products once hair is towel-dried for maximum volume retention.

• Shampoo: apply to wet scalp, massage, then rinse fully.
• Conditioner: concentrate on mid-lengths and ends, leave 1–2 minutes, then rinse.
• For extra lift, blow-dry with a round brush or use a root-lifting mousse.

What ingredients deliver the main benefits and why were they chosen?

OUAI selected a blend of strengthening proteins, botanical extracts, and lightweight oils to balance moisture, manageability and lift. Ingredients are chosen to be effective without adding excess weight or harsh surfactants that can strip hair.

• Keratin and biotin: support strand strength and resilience.
• Marshmallow root: adds slip for easier detangling and natural volume.
• Shea butter and avocado oil: provide nourishing moisture without heavy buildup.

Who this is for: The OUAI Fine Shampoo and Conditioner Set is ideal for people with fine, limp, or thinning-looking hair who want more body and manageable texture without heavy products or harsh sulfates. It also suits anyone seeking a cleaner ingredient profile—free of parabens and phthalates—while maintaining everyday ease in their haircare routine.
