Rated 5 out of 5 by from Blonde clients are in heaven This Brightening Shampoo is fantastic. The longevity of clients blondes are outstanding. No more having them coming in brassy or slightly lavender. I have used it in place of glosses over and over again and am so happy with the bright blonde results.

Rated 5 out of 5 by from K18 triple brighter shampoo works great. This triple brightening shampoo by K18 is an amazing pretoning shampoo that also helps with Moisturize and calm bleached hair. It actually works so good you may skip the toner I definitely recommend you buying these so that you can retell them to your clients they will love you when they go home and their hair turns yellow and they can fix it instantly with this. One of my new salon staples

Rated 5 out of 5 by from Creates a clean blonde I absolutely love this product! I noticed a big difference in the tone of my blonde hair after the 2nd use. While other purple shampoos tend to leave an oversaturation of tone on the hair and often making it appear a little dull, this product truly created a clean blonde. It definitely helps in stopping a build up of minerals from hard water. I highly recommend this to any blonde looking to have a bright but toned look between color services.

Rated 5 out of 5 by from Great texture, lather and Brightness I noticed that this works the best on freshly highlighted hair vs. growth out/dull highlights. I also find it most effective if it's done as a 2nd wash.
