I love the John Frieda color lines. I use the Brilliant Brunette shampoo, conditioner, colorglaze & finishing-gloss. It's a great way to keep your natural hair color but still get so many great compliments on your haircolor.
I use the brunette one. I dye my hair dark brown, it just maintains the colour, keeps it nice and glossy less frizz too]. As long as you wash it out properly it won't stain your clothes, it lasts for ages too!
