OUAI Hair Thickening Spray — Volumizing & Thickening Mist, 6 fl oz, lightweight lift + 450°F heat protection

OUAI Hair Thickening Spray is a lightweight volumizing mist that instantly increases hair fullness and body while offering heat protection up to 450°F.

This spray is formulated to add visible thickness and long-lasting lift to flat, fine, or thinning hair without leaving a crunchy finish. Designed for daily styling, the formula blends volume polymers and texturizing agents so you can create touchable, bouncy styles from roots to ends. It works best when applied to damp hair before blow-drying, but also layers well under other styling products for extra hold and dimension.

How will this spray change my hair’s appearance?

OUAI Thickening Spray gives hair a fuller silhouette by expanding individual strands and building root lift. The result is immediate body and enhanced texture that reads thicker across the entire style.

• Boosts strand diameter for fuller look
• Creates root lift for visible volume
• Improves texture so styles hold shape

Can I use it with heat tools and other products?

Yes — the formula includes heat-protectant ingredients rated to help shield hair up to 450°F, making it safe to blow-dry, curl, or flat-iron after application. It layers smoothly under serums, creams, or hairsprays without causing stiffness when used as directed.

• Mist on damp hair before blow-drying for best results
• Compatible with styling creams and finishing sprays
• Helps reduce friction from hot tools during styling

How do I apply it for maximum volume?

Evenly spray the product onto damp hair from roots to ends, then blow-dry while lifting at the roots with your fingers or a round brush. For targeted body, concentrate a few extra sprays at the crown or along the part line.

• Spray 6–8 inches away for even coverage
• Use a round brush at roots for amplified lift
• Finish with light misting on dry hair for extra texture

Will this work on all hair types and textures?

The Thickening Spray is formulated to benefit a wide range of hair types, particularly fine to medium strands that need more body. Coarser or very curly hair may notice added texture and hold, though results vary by individual hair density and porosity.

• Ideal for fine, limp, or thinning hair
• Also adds texture to straight or wavy hair
• Can be used sparingly on thicker hair for definition

Who is this for: OUAI Hair Thickening Spray is tailored for anyone seeking instant, touchable volume and improved hair fullness—especially those with flat, fine, or thinning hair who want a lightweight, heat-safe styling boost. It’s a practical everyday tool for people who style with heat and need reliable lift without stiffness, and for anyone who prefers salon-ready volume from a simple at-home routine.
