Acidic Color Gloss Heat Protection Leave-In Treatment is a no-rinse leave-in spray from Redken formulated at an acidic pH to protect color-treated hair, in the heat protectant category. It shields hair up to 450°F (232°C) during blow-drying or hot-tool styling while working to preserve color vibrancy and shine between salon color services.
The spray is built on a silicone base (dimethicone and an amodimethicone derivative) for smoothing and detangling, combined with soybean oil and tocopherol (vitamin E) for light conditioning, within Redken's acidic-formula approach intended to help keep the hair cuticle closed after a color service.
It's applied to clean, damp hair — typically from mid-lengths to ends — and left in without rinsing before blow-drying or heat styling. It's designed to work as part of Redken's full Acidic Color Gloss system (shampoo and conditioner), but functions on its own as a standalone heat protectant and detangler for color-treated hair.
