Review on Intense Color Watercolors Shampoo 8.5 oz (Silver) by Laura Thomas

I'm allergic to PPD and can't use hair dye or toner. I get highlights to hide my gray and struggle with copper tones because I can't use toner, so my stylist recommended this shampoo. I've tried many different purple shampoos, none of which had any noticeable effect. I've only used this shampoo twice but I'm already seeing a significant improvement in color. My highlights are getting ashy, I love this shampoo. I also feel like my hair is fuller and softer than before. UPDATE: It's the second week and I'm still in love, I see if you overdo it your hair turns lavender. If you notice this, just take a break for a while (now I use every other wash). I got so many compliments everyone thinks I just walked into the salon.
