What It Does

Redken’s Blonde IQ 9+ Calibrated Anti-Brass Lightener is a dual-action oil-powered system designed for advanced neutralization and up to 9 levels of powerful clean lift. The proprietary technology efficiently drives neutralization power to the hair’s core; breaking down eumelanin and pheomelanin for your most neutralized blonde.

Perfect for balayage, foiling and all over blonding, Redken Blonde IQ 9+ is to only be used with Redken Pro Oxide Oil Developers 10 – 30 Volume to guarantee precise results you expect.

What Else You Need to Know

Redken Blonde IQ 9+ provides no swelling, better saturation, even lift, and precise application, delivering a powerful clean lift for all hair types and textures. Its versatile formulation is ideal for a wide range of services, including balayage, foiling, and all over blonding.

Wear suitable disposable gloves. Mix product in a well-ventilated area. Follow mixture ratios carefully, or damage to hair or scalp including irritation, hair loss or chemical burns could occur.

1. Put the recommended amount of Blonde IQ™ 9+ Lightener and Pro-Oxide Oil Developer 10V (3%), 20V (6%) or 30V (9%) in a non-metallic bowl.

Rated 5 out of 5 by from Fave lightener! This is my new go to lightener! The lift is clean and the consistency is smooth and glides on the hair. It lifts fast but keeps the hair healthy. No swelling it’s great all around!

Rated 5 out of 5 by from My go to lightener Love this lightener, the lift and consistency is my favorite. Great for more fragile hair as it’s gentle but still effective. Glad they came out with the 10 volume to pair with it also.

Rated 5 out of 5 by from New Salon Fave Love this lightener!! My new favorite for blonding my dark leveled girlies. It’s amazing for the consistency and levels of lift in a short amount of time. I will say, read the label as it has preferred developer to powder ratio and don’t use heat while processing!

Rated 5 out of 5 by from Best Lightner Being a cosmetologist for 20 years I have tried many different brands of lighteners. This is by far the best one. Controlled lift without damaging hair.
