How long will a 140ml bottle last?

Usage depends on hair length and frequency: for short-to-medium hair used daily, expect several weeks to a couple of months. Long or thick hair and daily reapplications will shorten that timeframe.

Is it safe to use on colour-treated or chemically treated hair?

Yes — the leave-in is formulated to improve manageability and moisturise strands, which benefits colour- or chemically-treated hair. Always patch-test if you have a specific sensitivity and follow with your usual colour-care routine.

Is this good value compared with cheaper leave-ins?

Ouai positions this as a premium, multi-tasking product with a lightweight spray delivery and brand-specific scent. If you prioritise a fine-mist application and brand formulation, it can be worth the price; if you only need basic detangling, a budget alternative may suffice.

Can I return this product if I change my mind?

Overview

Ouai Leave-In Conditioner 140ml is a lightweight spray leave-in designed to detangle, moisturise and tame frizz while preparing hair for styling. Packaged in a convenient 140ml mist bottle, it’s aimed at people who want a quick, everyday product to improve manageability without heavy buildup — ideal for busy routines, travel, or as a styling primer. The formula works best on damp hair to smooth strands, reduce knots and add slip for easier combing, making blow-drying and heat-styling more efficient. Users with wavy, curly, textured or colour-treated hair will particularly appreciate its ability to control frizz and add moisture; those with very fine hair should apply sparingly to avoid weighing roots down.
