For a girlie who is not a natural blonde but wishes to be, I recently started opting for a balayage instead of continuously coloring my whole head—because I simply couldn’t keep up with my dark roots. But after a few months, my bright blonde hue always fades into a brassy, yellowy shade—essentially, a fake blonde’s worst nightmare.
I’ve searched high and low for the best purple shampoo for blonde hair that would bring my color back to the cool, blonde shade I love while repairing damage from bleach and preventing any fallout. To the rescue: Redken Color Extend Blondage range—a shampoo, conditioner, and mask—promises to be every blonde’s cure-all.
I was sent the complete Color Extend Blondage collection courtesy of the brand and had to test it out myself to see if this is not only the best shampoo for blonde hair but also the best conditioner for blonde hair. To take my hair-brightening routine one step further, I wanted something I could use in between actual hair-washing days too, so I opted to try out the hair mask in the shade violet + blue as part of the system.
Read on for a full Redken review of the Color Extend Blondage system and how I used it to transform my blonde locks.

What Does Color Extend Blondage Do?
Redken’s Color Extend Blondage complete system is a highly-concentrated purple pigment treatment for blonde and highlighted hair that fights brassy undertones in just 5(-ish) minutes.

The system starts with the Redken Color Extend Blondage Shampoo which immediately cleanses and tones blonde and highlighted hair to remove any brassiness. It protects color, repairs damage, and adds softness. This product checked all the boxes for me in my search for the best shampoo for blonde hair.
Now, you might ask, “Well, does Redken Color Extend Blondage have sulfates?” And while this shampoo and the rest of the line contain sulfates (only to give the best cleansing experience), it’s also stocked with wheat proteins, amino acids, and glycerin to help strengthen and repair your tresses from the inside out while restoring your blonde color to a cool, bright shade—as if you just walked out of the salon from a hair coloring session.

Next up is the color-depositing Redken Color Extend Blondage Conditioner, made with Citric Acid to repair hair from the core as it detangles and moisturizes. The purple, brass-busting conditioner was created specifically for fragile blonde hair.
Redken Color Extend Blondage Mask
Finally, finish the hair care routine with the Redken Color Extend Blondage Mask. The anti-brass mask neutralizes yellow undertones with a purple ultra-pigment that ensures a bright, cooler end result. It comes in three shades to suit your shade of blonde—Icy Blonde, Rose Blonde, and Honey Beige—making its case for the best mask for blonde hair across the board.
How Do I Use Redken Color Extend Blondage?
First, apply the shampoo to wet hair, lather, and rinse well. Leave the lather on for three to five minutes for maximum benefits to let it settle in. Redken suggests using gloves because each product is so pigmented that it could stain your hands. Following a lather and rinse of the shampoo, apply the Color Extend Blondage Conditioner—the best conditioner for blonde hair. Leave it in for three to five minutes, and rinse thoroughly.
Next, towel dry hair just a bit. Then apply the Color Extend Blondage mask to neutralize brass a step further while deeply conditioning hair. Comb through it to make sure it’s evenly distributed. Leave on for five to 10 minutes (five minutes for subtle deposit and up to 10 minutes for maximum deposit), and then rinse out.
Leave the mask on longer for an ashier look, or rinse sooner for just a quick color pick-me-up—no need to worry about breakage if you choose to keep it on for the full 10 minutes. The Triple Acid Protein Complex protects the cuticle, keeps hair strong and shiny—no matter your level of blonde—and leaves hair feeling soft, clean, and refreshed!
How Often Should You Use Redken Color Extend Blondage?
While working from home for the past two years, I started aiming to wash my hair only two times per week. Redken recommends only using the Color Extend Blondage system one to two times per week, so this ties in perfectly with my hair-washing schedule.
But if you’re like me and only wash your hair twice a week, according to Redken artist Adina Doss, you can use the system just once a week to keep your hair bright. It can also be mixed in with your regular shampoo to provide some brass-fighting pigment without overdoing it adds Redken Artist Jaclyn Harwood .

Before Redken Color Extend Blondage
My Redken Color Extend Blondage Review
I was shocked at how soft and shiny my hair was after even just my first use of the Redken Color Extend Blondage system. It was clear after one use that the shampoo and conditioner duo were effective, but after doubling down by adding the mask in the shade Icy Blonde to my hair-washing routine, I was sold. (I also noticed the system slightly lightened up my naturally dark roots, so they more seamlessly transitioned into my blonde balayage.)

Results after just one use!
After several more uses, I can’t imagine not having this shampoo, conditioner, and mask in rotation. I could literally feel the typically dry texture of my hair softening with each use while it was simultaneously ridding my hair of that brassy hue that haunts me in between salon visits. I can finally stop losing sleep over my search for the best purple shampoo because I found something better—a complete “purple” hair care system that every bottle blonde needs to fake their dream locks.
