Redken Acidic Color Gloss Leave-In Heat Protection Spray for Color-Treated Hair — Protects to 450°F & Boosts Shine

Redken Acidic Color Gloss Heat Protection Leave-In Treatment Spray is a leave-in conditioner that conditions color-treated hair, seals the cuticle with an acidic formula and protects against heat up to 450°F while boosting salon-level shine.

The Redken Acidic Color Gloss line is a salon-formulated system designed to help maintain color vibrancy and finish hair with a reflective, glass-like shine. This lightweight leave-in spray works between salon visits to condition strands, flatten the cuticle and offer thermal protection so styling tools create smooth results without dulling your color. Use it as part of the Acidic Color Gloss routine for best performance.

How does this spray protect hair from heat styling tools?

The formula contains Invisible Shield Technology that forms a protective layer around the hair fiber, helping reduce direct heat impact from styling tools. It’s rated to protect hair from temperatures up to 450°F when used as directed, helping minimize surface damage during blow-drying, flat-ironing or curling.

• Thermal shield active helps disperse heat evenly across the strand
• Lightweight, non-greasy spray that won’t weigh down fine hair
• Works with hot tools including blow dryers, flat irons and curling wands

Will this help my color last longer and look shinier?

Yes — the acidic pH of the Acidic Color Gloss line helps lay down the cuticle for a smoother surface that reflects light better, so color appears more vibrant and glossy. Regular use of this leave-in treatment between washes helps preserve salon color and maintain a high-shine finish.

• Acidic formula seals cuticles to lock in color molecules
• Enhances surface smoothness for improved light reflection
• Pairs with Acidic Color Gloss shampoo, conditioner and treatments for extended results

How should I use this leave-in spray for best results?

Apply to towel-dried hair, spraying evenly from mid-lengths to ends before styling; there’s no need to rinse. Comb or brush through to distribute, then blow-dry or style as usual. For intensified gloss, use alongside the Activated Glass Gloss Treatment and sulfate-free Acidic Color Gloss Shampoo.

• Spray on damp hair, focusing on mid-lengths and ends, then comb through
• Style with heat tools up to 450°F as needed
• Use regularly with the Acidic Color Gloss system for maximum color longevity

Is this suitable for my hair type and color-treated needs?

The lightweight formula is formulated for color-treated and shine-seeking hair and is safe for a range of textures, from fine to thick. It helps maintain salon gloss without heavy buildup; however, those seeking intense reconstructive repair may prefer concentrated treatments in addition to this leave-in gloss spray.

• Recommended for color-treated, highlighted or glossed hair
• Works on fine, medium and coarse hair textures without weighing hair down
• Complements deeper conditioning or bond-repair treatments when needed

Who is this for: Redken Acidic Color Gloss Heat Protection Leave-In Treatment Spray is intended for people who want to protect their color and achieve a luminous, salon-quality shine while using heat tools. It’s ideal for anyone who schedules regular color services and wants an easy, lightweight product to protect color vibrancy, smooth the cuticle and add visible gloss between professional glossing or coloring appointments.
