Engineered for modern blonding techniques, this high-performance lightener delivers powerful lift with improved tonal control.
The Redken Blonde IQ 9+ Lightener features advanced calibrated anti-brass technology, which works during processing to help counteract warm undertones as hair lifts. This helps achieve cooler, brighter blonde results while reducing excessive brassiness that often appears during high-lift services.

Create dimensional blonde results in a single color service with Redken Blonde IQ 5 Calibrated Anti-Brass High-Lifts, a professional high-lift permanent hair colour range designed to simultaneously lift and tone natural hair while helping neutralize unwanted warmth.
Powered by Redken's proprietary Advanced Neutralization Technology, the creamy formula delivers up to 5 levels of lift while depositing carefully calibrated toning dyes for synchronized neutralization. This allows colourists to lift and tone in one step, creating natural-looking, dimensional blonde results without requiring a separate toning service in suitable applications.
The range features 9 intermixable shades spanning cool through neutral tonal families, giving professional colourists flexibility to customize blonde results for different clients. Blonde IQ 5 High-Lifts are suitable for all hair types and textures and can be used for both on-scalp and off-scalp techniques.

Benefits & Features
Up to 5 Levels of Lift: Provides powerful high-lift performance for creating brighter blonde results without a traditional lightener in suitable applications.
Lift + Tone in One Step: Simultaneously lifts natural pigment and deposits tone for streamlined blonde services.
Advanced Neutralization Technology: Combines toning dyes with twice the concentration of oxygen molecules compared with Redken permanent hair colour mixed at a 1:1 ratio.
Anti-Brass Performance: Helps counteract unwanted warmth as the hair lifts for cleaner, more controlled blonde results.
9 Intermixable Shades: Allows colourists to customize formulations and create a variety of cool-to-neutral blonde results.
Cream Formula: Provides easy mixing, controlled application, and easy rinsing.
Versatile Professional Application: Suitable for both on-scalp and off-scalp colouring techniques.

Because high-lift blonde should deliver more than lift—it should deliver the right tone, too.
What Makes It Stand Out?
Unlike conventional high-lift colour that may require additional toning to refine unwanted warmth, Redken Blonde IQ 5 Calibrated Anti-Brass High-Lifts are engineered to synchronize the lifting and toning processes.
Redken's Advanced Neutralization Technology combines increased oxygen concentration with calibrated toning dyes, allowing lift and neutralization to occur together. This provides up to five levels of lift while helping colourists achieve true-to-tone, dimensional blonde results in one service.
The system is particularly well suited to virgin hair and root-regrowth applications when a one-step lift-and-tone service is desired. The shades can also be intermixed, giving professional colourists additional flexibility when creating customized blonde formulations.
