This toning spray is for people with pre-lightened hair — natural platinum blondes, colour-treated or highlighted blondes, and gray or white hair — who want to control yellow, brassy undertones between washes. Because it's a simple spray-in leave-in with no mixing or processing time, it works equally well as a salon add-on or a home step in a regular hair-care routine, for any hair length.

Unlike a purple shampoo, which only tones hair for the few minutes it's lathered in before rinsing away, this spray stays on the hair after it dries, so the color-correcting effect keeps working between shampoos instead of resetting to zero right after a wash. That makes it useful for stretching time between salon glaze or toning appointments, or for anyone whose blonde warms up faster than their wash schedule allows for.

Shake the bottle well before each use. Spray it onto clean, damp hair after shampooing, and comb it through evenly from roots to ends. Leave it in — it isn't meant to be rinsed out. It can be reapplied daily or just a few times a week, depending on how quickly yellow tones reappear.

The formula earns its keep by working between washes: it corrects brassiness the moment it's sprayed on, requires no rinse, and layers into a normal routine without adding a step at the sink. The tradeoff is the alcohol-forward base — it can leave already-dry or heavily processed blonde ends feeling stripped if used daily, and because the violet pigment is left in rather than rinsed out, overuse on very pale or previously toned hair can tip the color ashy or faintly purple until it's washed out or grown through.
