OUAI Fine Hair Shampoo Travel Size — 3 oz Biotin Thickening, Lightweight Volumizing & Strengthening Formula

OUAI Fine Hair Shampoo (3 oz) is a travel-size biotin thickening shampoo that boosts lift and strengthens fine, flat hair without weighing it down.

This lightweight, color-safe formula combines biotin, hydrolyzed keratin, and chia seed oil to create fuller-looking hair while gently cleansing. Sulfate-, paraben-, phthalate- and gluten-free, the shampoo is designed for fine or thinning hair that needs volume, texture, and reduced breakage—ideal for use on color-treated and chemically processed hair. The compact 3 oz bottle fits carry-on bags and gym packs so you can keep a lift-ready routine while traveling.

How does this shampoo add volume without making hair heavy?

OUAI Fine Hair Shampoo targets root lift and mid-length body through ingredients that thicken individual strands rather than coating them with heavy oils. Hydrolyzed keratin smooths and strengthens the shaft, while chia seed oil provides lightweight nourishment that preserves bounce.

• Biotin supports thicker-feeling strands at the root.
• Hydrolyzed keratin repairs and adds reflective shine.
• Chia seed oil conditions without residue or weight.
• Gentle cleansers remove buildup to reveal natural body.

Will it protect color and chemically treated hair?

Yes — the formula is safe for color-treated, keratin-treated, and chemically processed hair because it avoids harsh sulfates and parabens that can strip dye or treatments. It maintains moisture balance while helping to prevent breakage common after chemical services.

• Sulfate-free cleansing preserves color vibrancy.
• Paraben- and phthalate-free for gentler daily use.
• Strengthening keratin reduces friction and split ends.
• Lightweight conditioning keeps treated hair manageable.

How do I use it for best results on travel or at home?

Apply a small amount to wet hair, focusing on the scalp and roots, then work through to the ends and rinse. For fuller results, follow with OUAI Fine Conditioner and add OUAI Thickening Spray at the roots when styling for lift that lasts through the day.

• Use a quarter-sized amount for short hair, more for longer lengths.
• Massage at the scalp to stimulate lift and remove product buildup.
• Rinse thoroughly and pair with OUAI Fine Conditioner for volume balance.
• Layer OUAI Thickening Spray for extra root support and texture.

What scent and sensory experience does the shampoo provide?

The shampoo carries OUAI's Mercer Street fragrance, a fresh, modern blend with top notes of Italian lemon, a floral iris heart, and a warm white musk base. The lightweight lather rinses clean, leaving hair feeling airy and smelling subtly refined without heavy perfume residue.

• Mercer Street scent: citrus, iris, white musk.
• Fine, foaming texture that rinses easily.
• Leaves hair soft to touch with increased body.
• Compact 3 oz size is TSA-friendly for travel.
