OUAI Fine Hair Thickening Shampoo Travel Size (3 oz) — Volume-Boosting, Color-Safe for Thin Hair

OUAI Fine Hair Shampoo Travel Size is a 3 oz thickening shampoo formulated to boost volume, strengthen fragile strands, and gently cleanse fine or thin hair without weighing it down.

Packaged for travel and trial, this compact bottle delivers OUAI's volume-boosting formula with biotin, hydrolyzed keratin, and chia seed oil to add body, reduce breakage, and improve manageability. The sulfate- and paraben-free blend cleans while protecting color and chemical treatments, and it carries OUAI's Mercer Street fragrance with bright lemon, soft iris, and warm white musk. Use it as part of a routine with OUAI Fine Conditioner and OUAI Thickening Spray for fuller-looking hair.

How does this shampoo create volume without weighing hair down?

The formula uses lightweight thickening agents like chia seed oil plus hydrolyzed keratin that coat and plump strands rather than saturating them. Gentle surfactants clean oils and buildup so roots lift naturally, while biotin supports stronger hair less prone to breakage.

• Chia seed oil: adds body without heaviness
• Hydrolyzed keratin: smooths and helps strands appear fuller
• Biotin: supports resilience to reduce breakage
• Sulfate- and paraben-free surfactants: gentle cleansing for light root lift

Will this travel-size shampoo work for color- or chemically-treated hair?

Yes — the formulation avoids harsh sulfates, parabens, phthalates, and gluten, making it safe for color-treated, keratin-treated, and other chemically processed hair. It cleans effectively while helping preserve treatment results and shine.

• Color-safe surfactants to protect pigments
• No harsh detergents that strip treatments
• Hydrolyzed keratin restores smoothness and shine
• Small 3 oz size ideal for travel and trial use

How should I use this shampoo to get the most lift and strength?

Apply to wet hair, focusing on the roots and scalp for cleansing and volume, then work the lather through to the ends. Rinse and follow with OUAI Fine Conditioner to maintain bounce without adding weight, and add OUAI Thickening Spray for extra lift at the roots.

• Massage into scalp for root activation
• Distribute to ends for balanced conditioning
• Pair with OUAI Fine Conditioner for lightweight moisture
• Finish with OUAI Thickening Spray to amplify volume

What scent can I expect from the Mercer Street fragrance?

Mercer Street is a modern, travel-ready fragrance with bright Italian lemon at the top, a clean floral iris heart, and a soft white musk base. The scent adds a subtle, polished finish to clean hair without overpowering.

• Top: fresh Italian lemon for brightness
• Heart: soft iris for a clean floral touch
• Base: white musk for a lasting, warm finish
• Light and suitable for daily use

Who is this for: OUAI Fine Hair Shampoo Travel Size is designed for anyone with fine, thin, or fragile hair who wants immediate root lift, stronger-looking strands, and a gentle clean while on the go. It's also a good option for travelers, gym bags, and first-time users who prefer a smaller size before committing to a full bottle. If you color- or chemically-treat your hair but still need volume and lightweight care, this travel-size shampoo fits neatly into your routine.
