Bruchilda, I came across a review of the silver formula a long time ago. I will search for it, and post for you. Not sure if it was here on the forum or a blog. I will search in a bit and post it for you. The reviewer said it did not worked as the "original" and did not lasted as much, but did not altered her color. That is why I never purchased the silver (and I was so determined to try it!)
