OUAI Medium Hair Shampoo Travel Size 3 oz — Hydrating, Sulfate-Free for Color-Treated Hair

This compact 3 oz bottle delivers OUAI's Mercer Street scent and a balanced, moisture-forward formula designed for hair described as "in-between" — not fine, not thick. It blends babassu and coconut oils with keratin and kumquat extract to detangle, smooth frizz, and add shine while remaining safe for color-treated and chemically processed hair. The formula is free of sulfates, parabens, and phthalates, and is cruelty-free and gluten-free, making it a travel-ready option for daily cleansing and midweek refreshes.

How does this shampoo hydrate without weighing hair down?

OUAI Medium balances lightweight plant oils and protein to moisturize strands without leaving a heavy residue. Babassu oil captures hydration at the scalp, while coconut oil helps seal ends, and keratin provides slip for easier detangling and smoother cuticles.

• Babassu oil for scalp and strand hydration
• Coconut oil to help protect and reduce breakage
• Keratin to smooth frizz and improve comb-through
• Light kumquat extract for a glossy finish

Will it preserve my color-treated or chemically processed hair?

The shampoo is formulated without sulfates and with gentle surfactants that cleanse effectively while minimizing color fade. It’s marketed as safe for keratin-treated, color-treated, and chemically processed hair when used as directed.

• Sulfate-, paraben-, and phthalate-free surfactant system
• Gentle enough for processed hair routines
• Pairs with OUAI Medium Conditioner to lock in moisture
• Travel size fits TSA rules for short trips

How does it help manage frizz and breakage during styling?

The combination of oils and keratin reduces friction and smooths the hair surface, which helps limit mechanical breakage and frizz during blow-drying or air-drying. Using the shampoo followed by OUAI Medium Conditioner and a small amount of OUAI Hair Oil can amplify smoothing and shine.

• Keratin smooths the cuticle for less frizz
• Coconut oil targets split ends and fragile lengths
• Use with OUAI Hair Oil for added slip and shine
• Suitable for straight, wavy, curly, and coily textures

What sensory experience and scent should I expect on the go?

The travel size retains OUAI’s Mercer Street fragrance profile — a fresh, modern blend with Italian lemon top notes, jasmine heart tones, and a subtle white musk base. The compact bottle is crafted to be convenient for gym bags and carry-ons, offering a practical way to refresh hair between washes.

• Mercer Street scent: lemon, jasmine, white musk
• 3 oz travel-friendly bottle for portability
• Creates a gentle lather for easy rinsing
• Ideal for daily or midweek cleansing

Who is this for? OUAI Medium Hair Shampoo travel size is made for people with medium-thickness hair looking for a lightweight, nourishing cleanser that supports color longevity and reduces breakage. It’s a convenient option for travelers, gym-goers, or anyone wanting to trial OUAI’s Medium routine before committing to full-size bottles. If you have very fine hair that tends to oil quickly or extremely thick hair that needs heavy conditioning, consider testing in small amounts or pairing with a richer conditioner as needed.
