OUAI Medium Hair Shampoo & Conditioner Set — Sulfate-Free Duo with Keratin & Shea Butter (10 fl oz)

OUAI Medium Hair Shampoo and Conditioner Set is a sulfate-free cleansing and conditioning duo formulated with keratin, shea butter, and avocado oil to strengthen, smooth, and add shine to medium-thickness hair.

Made for hair that falls between fine and thick, this pair blends moisturizing oils and protein to help manage frizz, reduce breakage, and leave strands feeling softer without weighing them down. Both formulas avoid sulfates, parabens, and phthalates, and are sized for everyday use at home or while traveling. The scent-forward OUAI identity and hair-friendly actives make this set a simple upgrade to a balanced hair-care routine.

How does this set improve medium-thickness hair?

The shampoo gently cleanses without stripping natural oils, while the conditioner deposits hydration and proteins to reinforce the hair shaft. Together they smooth surface cuticles for visible shine and easier detangling, supporting healthier-looking hair over time.

• Keratin helps strengthen and supports resilience against breakage.
• Shea butter and avocado oil provide replenishing lipids for softness.
• Sulfate-free formula preserves natural moisture and color vibrancy.
• Kumquat extract and botanical oils promote manageability and shine.

Will the shampoo and conditioner weigh my hair down?

Formulated specifically for medium hair, the textures are calibrated to avoid heavy buildup while delivering effective moisturization. You get conditioning benefits without the flatness associated with overly rich products.

• Light-to-medium conditioning profile balances hydration and volume.
• Non-greasy oils like babassu and coconut are used in moderation.
• Rinses cleanly to maintain natural movement and body.

Are these products safe for color-treated or chemically styled hair?

Because the shampoo is sulfate-free and both formulas are free of parabens and phthalates, they are compatible with many color and chemical services. They focus on gentle cleansing and reparative ingredients rather than harsh detergents that can strip dye.

• Sulfate-free gentle cleansing helps preserve hair color longer.
• Keratin supports structural integrity after chemical processes.
• Use alongside your salon-recommended color-care routine for best results.

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

Apply shampoo to wet hair, lather through roots to ends, then rinse. Follow with conditioner, concentrating on mid-lengths to ends, leave for a minute or two, and rinse thoroughly for smoother, more manageable medium hair.

• Shampoo: focus on scalp to lift oils and impurities.
• Conditioner: apply from mid-shaft to ends; avoid roots if you want extra volume.
• For deeper repair, pair with OUAI treatments or use a weekly mask.

Who is this for: This OUAI Medium Shampoo and Conditioner Set is aimed at people with medium-thickness hair who want a balanced, everyday cleansing and conditioning system. It suits those seeking frizz control, improved manageability, and shine without heavy formulas—ideal for users with natural, colored, or lightly processed hair looking for salon-inspired results at home.
