Anyone with color-treated hair who wants extra fade protection and detangling between washes. It's a simple spray-and-style step, not a professional-only treatment, so it suits both salon clients maintaining their color at home and everyday retail shoppers.

Color fades fastest in the days right after a salon visit, and this spray is built to slow that specific process rather than just adding shine: the pH 4.5 system physically tightens the hair's outer layer around the color pigment sitting in the cortex, and because it's a leave-in, that protection stays on the hair between washes rather than rinsing away. The added heat protection also means it can double as a pre-styling step, so it's one product covering two jobs for anyone who blow-dries or flat-irons color-treated hair regularly.

Use on towel-dried hair after washing, before any heat styling.

• Shake the bottle well before use.
• Spray onto towel-dried hair in sections, focusing on mid-lengths to ends.
• Comb or work through with fingers — do not rinse.
• Style as usual; can be used before heat tools up to 230°C/446°F.

Pros:

• Leave-in format needs no rinsing step, so it fits quickly into a routine
• pH 4.5 formula is built specifically to slow color fade, with the brand citing roughly 90% color retention through 30 washes
• Built-in heat protection up to 230°C before blow-drying or flat-ironing
• Vegan formula with no animal-derived ingredients

Cons:

• Addresses surface color protection only — it doesn't replace a color-safe shampoo and conditioner routine
• Fragranced formula contains several common fragrance allergens (linalool, limonene, geraniol), which may not suit fragrance-sensitive scalps
• As a leave-in, over-application on fine hair can't be rinsed back out
