Review (2/5): If you want purple hair....
I have silver hair, and it needs a "touch up" once a week with a special shampoo. I've tried other brands, started with Clairol's Shimmer Lights, too harsh, and eventually ended up trying this brand due to all the great reviews. I wish I could return it. I much prefer the Touch of Silver brand for a few reasons: smells better, you don't need to hear gloves in order to use and doesn't leave your hair with the "old lady syndrome of purple hair!" I leave it on for two minutes, least amount recommended to get rid of brassiness and I always have a tint of purple in my hair after use. It usually goes away after a couple of shampoos, but that's not the point. Touch of Silver is less expensive (yes it's a smaller bottle and comes from overseas) but it doesn't stain your hair or hands and does the job much better in my opinion.
