OUAI Medium Hair Shampoo — Hydrating 10 oz for Frizz Control & Color-Safe Shine

OUAI Medium Hair Shampoo is a hydrating, frizz-control cleanser formulated for hair that's neither fine nor very thick, designed to clean, nourish and restore shine.

Built for in-between hair textures, this 10 oz shampoo targets dryness and frizz while remaining safe for color-treated, keratin-treated, and chemically processed hair. The formula pairs hydrating plant oils with shine-boosting extracts and keratin to detangle, smooth, and strengthen strands without sulfates, parabens, phthalates, gluten, or cruelty. The scent profile—Mercer Street—adds a fresh citrus and floral finish to your routine.

Who is this shampoo designed for?

This cleanser is formulated for medium-density hair—textures that aren’t particularly fine or very coarse—suitable for straight, wavy, curly, and coily patterns. It balances moisture and manageability so strands look healthier without heavy buildup.

• Ideal for medium-thickness and mixed textures
• Safe for color, keratin and chemically treated hair
• Works across multiple curl patterns
• 10 oz size for regular at-home use

How does it hydrate and reduce breakage?

Rich plant oils in the formula replenish lost moisture while protein and botanical extracts help reinforce strand structure. Together these ingredients minimize friction, reducing split ends and breakage during styling and detangling.

• Babassu oil restores hydration to scalp and hair fibers
• Coconut oil helps seal the cuticle and protect ends
• Keratin supports smoother, easier-to-comb strands
• Kumquat extract revives reflection and sheen

Will it make my hair heavy or greasy?

Formulated for balance, the shampoo cleans without stripping while avoiding heavy silicones or waxy residues. It aims to leave hair soft and manageable, not weighed down, when used as directed and rinsed thoroughly.

• Sulfate-free cleansing for gentler removal of dirt
• No parabens or phthalates that can build up over time
• Rinse well from roots to ends to prevent residue
• Follow with OUAI Medium Conditioner for optimal results

How should I incorporate it into my hair routine?

Use it as your regular shampoo, focusing on the scalp to lift oils and environmental debris, then work the lather to the ends. Pair with the matching OUAI Medium Conditioner and finish with OUAI Hair Oil for enhanced frizz control and shine.

• Apply to wet hair, massage into the scalp, and work through mid-lengths to ends
• Rinse completely and repeat only if needed
• Follow with OUAI Medium Conditioner for hydration balance
• Layer OUAI Hair Oil for extra smoothness and shine

Who is this for? If your hair falls between fine and thick and you want a gentle, effective cleanse that tames frizz, restores shine and supports treated hair, OUAI Medium Hair Shampoo fits naturally into your routine. It’s a good choice for anyone seeking a balanced, cruelty-free formula with nourishing oils and proteins that doesn’t compromise color or chemical services.
