I dyed my hair pastel purple, and this seemed to help it hold the color. The smell is really strong pepperminty and a little much for me, but it's worth it to keep the color in. I've had to re dye significantly less than some other people I know, possibly because of the conditioner. It isn't the most moisturizing conditioner, but none of the ones with color really are. I was nervous with mixing at first so I bought this, but now that I'm a little more confident I'll probably just add dye to cheap conditioner, but it was nice to have something I knew was the right shade while I figured it out.
