Redken Acidic Color Gloss Leave-In Treatment Spray — Heat Protection to 450°F, Color-Sealing Shine

Redken Acidic Color Gloss Heat Protection Leave-In Treatment Spray is a lightweight, leave-in conditioner that protects color-treated hair from heat up to 450°F while sealing the cuticle for intense, glass-like shine.

This salon-grade leave-in spray combines a color-preserving acidic formula with advanced heat-shield technology to strengthen and polish color-treated hair between salon visits. Designed to work with the Acidic Color Gloss collection, it conditions, reduces frizz, and helps maintain vibrant tone by smoothing the hair surface at a molecular level. The spray applies evenly and rinses out with your next wash, making it an easy daily step for anyone looking to extend salon results at home.

How does this leave-in help protect hair from thermal styling?

Redken’s formula delivers a protective barrier that stands up to hot tools, reducing the risk of heat-induced color fading and surface roughening. It’s formulated to shield strands at high temperatures while remaining lightweight and non-greasy.

• Heat protection rated up to 450°F to guard against flat irons and curling wands
• Invisible Shield Technology forms a thin protective layer without weighing hair down
• Spray application for even coverage on damp or dry hair

Will it help my color look fresher between salon visits?

The acidic pH of this treatment helps close and smooth the cuticle, which preserves color vibrancy and reduces dulling. Regular use can prolong salon gloss and keep hair looking polished until your next color appointment.

• Acidic formula seals the cuticle to lock in pigments
• Conditions and smooths for enhanced light reflection and tone depth
• Works best when paired with Acidic Color Gloss shampoo, conditioner, and treatment

How does it affect hair texture and manageability?

The spray functions as a multitasking leave-in conditioner that detangles, tames frizz, and boosts slip for easier styling. Hair feels softer and more manageable without a heavy residue, allowing natural movement and shine to show through.

• Light conditioning that improves comb-through and styling
• Reduces frizz and flyaways while smoothing the strand surface
• Maintains a natural-looking finish, not a stiff or waxy film

How should I use this spray for best results?

Use on towel-dried hair before heat styling, or on dry hair to refresh and protect prior to touch-ups with hot tools. A few light mists distribute evenly; concentrate on mid-lengths and ends where damage and color fade are most common.

• Apply 2–4 sprays on damp hair, comb through, then style as usual
• On dry hair, mist lightly and smooth with a brush before using hot tools
• Combine with Acidic Color Gloss Shampoo, Conditioner, and Activated Glass Gloss Treatment for optimal color longevity

Who is this for? This leave-in treatment is aimed at anyone with color-treated or glossed hair who wants to protect tone and boost shine while using heat tools. It suits all hair types that need lightweight conditioning and thermal defense—especially those seeking salon-quality finish and smoother, more reflective hair without heavy buildup.
