OUAI Medium Hair Shampoo — Hydrating, Sulfate-Free Color-Safe Formula 10 oz with Keratin & Coconut

OUAI Medium Hair Shampoo is a hydrating, sulfate-free cleanser formulated to nourish mid-density hair, protect color, reduce breakage, and add shine with coconut, babassu, kumquat and keratin.

This shampoo was created for hair that’s neither fine nor thick—strands that need moisture and strength without heaviness. The formula cleanses gently while delivering conditioning actives to help detangle, smooth frizz, and revive shine. It’s free of sulfates, parabens and phthalates, safe for color- and chemically-treated hair, and designed to pair with complementary OUAI products for best results.

How does this shampoo hydrate without weighing hair down?

Lightweight botanical oils combined with keratin give moisture and slip without coating the hair. Babassu oil penetrates to hydrate scalp and strands, while coconut oil targets ends to reduce split ends and breakage.

• Babassu oil: hydration that absorbs quickly
• Coconut oil: seals and protects dry ends
• Keratin: smooths cuticle for easier detangling
• Sulfate-free base: cleanses without stripping natural oils

Will this protect my color-treated or chemically processed hair?

The gentle, non-sulfate formula helps preserve salon color and supports chemically processed hair by avoiding harsh surfactants that accelerate fading. Conditioning ingredients smooth the cuticle to reduce friction and mechanical damage during styling.

• Free of sulfates, parabens and phthalates
• Color-safe cleansing that reduces premature fading
• Keratin and oils that help lower breakage during brushing
• Cruelty-free and gluten-free formulation

How should I use it for best results?

Apply this shampoo to wet hair, concentrating at the roots and then working through to the ends to distribute ingredients evenly. Rinse thoroughly and follow with OUAI Medium Conditioner to lock in moisture and smooth the hair shaft.

• Use a coin-sized amount for short hair; more for longer lengths
• Massage into scalp for cleansing and circulation
• Rinse and repeat if hair is heavily textured or product-heavy
• Finish with OUAI Hair Oil if extra shine or frizz control is needed

What scent and sensory experience can I expect?

The shampoo features OUAI’s Mercer Street fragrance with bright Italian lemon top notes, floral jasmine heart notes, and a warm white musk base. The lather is creamy but lightweight, leaving hair smelling fresh without stiffness.

• Mercer Street scent profile: citrus, jasmine, white musk
• Creamy, easy-to-rinse lather for comfortable use
• Leaves hair soft with balanced shine

Who is this for? OUAI Medium Hair Shampoo is aimed at people with mid-density hair textures—straight, wavy, curly or coily—that need hydration, strength and frizz control without heaviness. It’s a fit for those who color or chemically treat their hair and want a clean, cruelty-free formula that supports everyday styling and healthier-looking strands when paired with the rest of the OUAI routine.
