OUAI Medium Hair Shampoo and Conditioner Set — Sulfate-Free Keratin Duo (10 fl oz)

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

If your hair lands between fine and thick, this paired regimen is formulated to tackle common mid-weight hair needs: smoothing frizz, reinforcing strands and delivering moisture without weighing hair down. The set includes a nourishing shampoo that cleanses without sulfates and a balancing conditioner that softens and detangles while protecting against breakage. Key botanicals and oils work together to refresh texture and boost manageability for daily styling.

How will this set improve my hair’s day-to-day manageability?

The OUAI Medium duo focuses on lightweight conditioning and strengthening so hair is easier to comb, style and wear. The conditioner detangles while keratin and natural oils reduce friction and surface roughness, helping styling tools glide through more smoothly without adding excess weight.

• Keratin rebuilds and smooths cuticle texture for easier styling.
• Shea butter and avocado oil add slip for simpler detangling.
• Sulfate-free shampoo cleans without stripping natural moisture.
• Formulation aims to reduce breakage during wet brushing and styling.

Is this shampoo and conditioner safe for colored or chemically treated hair?

The sulfate-free cleansing base is gentler than traditional sulfates, which helps preserve color vibrancy and minimizes unnecessary fading. The conditioning blend provides moisture and protective slip, which can help reduce mechanical damage that accelerates color loss. However, avoid using extremely hot water and follow color-care recommendations for best results.

• Sulfate-free wash helps protect salon color and finishes.
• Keratin and oils support strand strength after chemical services.
• Suitable for many common color-treated hair types; always patch-test if uncertain.
• Follow with a color-safe mask or leave-in if you need extra protection.

What key ingredients are in the formula and what do they do?

OUAI combines protein, plant extracts and nourishing oils to address medium-hair concerns without heaviness. Keratin helps reinforce the hair shaft, kumquat extract lends conditioning properties, and a blend of babassu, coconut, shea and avocado oils restores softness and sheen.

• Keratin: helps strengthen and smooth the hair surface.
• Kumquat extract: provides lightweight conditioning benefits.
• Babassu & coconut oils: replenish lipids and boost shine.
• Shea and avocado: add hydration and protect against frizz.

How often should I use the OUAI Medium set and how much product works best?

Frequency depends on your scalp and lifestyle; most people with medium hair will find every-other-day or 2–3 times per week works well. Use a quarter-sized amount of shampoo on damp hair, lather and rinse thoroughly; follow with a similar or slightly larger amount of conditioner, focusing on mid-lengths to ends.

• Shampoo: start small and increase if needed for fuller lathers.
• Conditioner: concentrate on mid-lengths and ends, avoid roots if you have fine scalp oiliness.
• Adjust frequency for activity level and scalp oil production.
• Finish with cool-water rinse to help seal the cuticle for added shine.

Who is this for: This OUAI Medium Hair Shampoo and Conditioner Set is designed for anyone whose hair falls between fine and thick and needs strengthening, manageable moisture and frizz control without heavy residues. It’s best for people seeking a daily-friendly, sulfate-free routine that supports color-treated or chemically styled hair and for those who prefer formulas free of parabens and phthalates. If you want a balanced cleanse plus lightweight conditioning that helps reduce breakage and improve shine, this set is aimed at that everyday middle ground.
