I've been using John Freida Colour Renew for years. It keeps my highlights looking fresh between hair appointments. Its one of the few products I've found (outside of salon brands) that doesn't leave buildup on my hair. It's a bit pricey, but worth it!

Takes two treatments to really notive it was a bit darker. Great solution to lightened hair when it becomes too light. Richer and softer hair. Leave on awhile if you want it to deposit more color

Love this stuff! Smells amazing, lasts a decent amount of time (depending on how much you use each wash!) and isn't too costly. Makes my hair light and beautiful!

If you highlight or colour your hair blonde! This is a must! It kicks brassy colour to the curb. I use the shampoo and conditioner three times a week to maintain a light beige blonde colour! Love this stuff

Having bleached highlights, this product actually takes the brassiness off my hair. It keeps the blondes, blonde, and does not affect the rest of my hair colour. Amazing smell and also lathers really well, giving a clean feel to my hair.

I used this before I tried the go blonder and it got rid of the brassiness in my blonde hair, it also left my hair feeling healthier and softer so I would recommend it to any blonde

I love this stuff. The best ever. My hair loves it, I have silky hair when I'm done it lasts! I don't end vup as frizzy when I use it! I recommend it to other women. There's many different kinds all great!

I love dying my hair at home but always had to go to a salon to get the brass out after dying it blonde. With this shampoo I will never need to again! Gets rid of the brass shades within a couple of uses without drying your hair out. I buy this everytime I colour my hair blonde now!

This shampoo makes my hair silky smooth and does brighten the color. I would definitely recommend the shampoo and conditioner, they work great together and your hair will feel and look healthier

This is an amazing shampoo, it has the sweetest scent and it feels invigorating while you lather it into your scalp, it also leaves your hair without any residue. It really brings out your color and highlights and your hair is left feeling so soft and shiny, love this Shampoo, it can be pricey though ,but still a great product
