When I had my hair highlighted with blond tones, I tried John Frieda's "Sheer Blonde" shampoo & deep conditioner. I really liked it and also liked the styling products. I still use the styling products for blonde, even though I'm back to brunette now. I might start using the Brilliant Brunette when I run out of my current shampoo. I think if his other products are good, then the Brilliant Brunette stands a good chance! Go ahead and try it!

PS: it doesn't have a huge effect on the color of your hair, so there' s not really any risk
