Redken Acidic Color Gloss Leave-In Treatment Spray for Color-Treated Hair — Heat Protection & Lightweight Shine

Redken Acidic Color Gloss Heat Protection Leave-In Treatment Spray is a salon-grade leave-in conditioner that protects color, shields hair from heat up to 450°F, and builds intense, molecular-level shine.

This lightweight spray is formulated specifically for color-treated hair to lock color pigments in place and smooth the cuticle with an acidic pH. Designed as part of the Acidic Color Gloss system, it complements sulfate-free shampoo, conditioner, and the Activated Glass Gloss Treatment to extend salon results at home. The formula combines heat defense technology with conditioning agents that leave hair soft, glossy, and more resilient to styling damage.

How does this spray protect my color during heat styling?

The product uses Invisible Shield Technology to reduce color fade by minimizing thermal and mechanical stress on strands. Its acidic pH helps flatten the cuticle so color molecules stay sealed and reflective light enhances perceived brightness.

• Heat protection up to 450°F to guard against styling tools
• Acidic formula helps seal hair cuticles to lock color
• Lightweight, non-greasy mist that won’t weigh hair down
• Works with the Acidic Color Gloss routine for best longevity

Will it add shine without making hair feel heavy or sticky?

Yes — the spray is designed to produce a molecular-level gloss that reads as natural shine, not an oily finish. Conditioning agents smooth the surface of the hair, increasing light reflection while maintaining a soft, touchable texture.

• Acidic pH smooths the cuticle for high-gloss reflection
• Feather-light delivery for shine without buildup
• Suitable for fine to thick textures due to spray application

Can I use this on freshly colored hair and how does it fit into a routine?

The leave-in is safe for freshly colored hair and is intended as a finishing and protective step after washing and conditioning. For optimal results, apply to damp hair before heat styling or as a finishing mist to enhance shine and defend against thermal tools.

• Use after Acidic Color Gloss shampoo and conditioner or Activated Glass Gloss treatment
• Spray on damp hair before blow-drying or on dry hair before flat/curly tools
• Reapply lightly on dry hair for added gloss on non-wash days

Does it help with general hair health or only color protection?

While focused on color retention and shine, the formula also provides conditioning benefits that reduce frizz and help the hair surface look healthier. It won’t repair major structural damage but does improve appearance and manageability by sealing the cuticle and protecting from daily stressors.

• Conditions to reduce tangling and frizz
• Seals cuticle to improve smoothness and shine
• Supports salon results between professional gloss treatments

Who is this for: This treatment is aimed at anyone with color-treated or highlighted hair who wants longer-lasting color, high shine, and reliable heat protection. It’s especially useful for people who heat-style regularly or follow a color-maintenance routine and want a lightweight, salon-quality leave-in step that pairs well with Redken’s Acidic Color Gloss line.
