I have never died my hair before and I love my natural hair color. It's blonde with natural highlights and lowlights. Are there any temporary hair dyes that wash out in only a couple washes?

A product that I've used and liked a lot is Goldwell Colorance Soft Color Foam Colourant Mousse. The manufacturer indicates that it washes out after 6-8 washes (I think it's a bit faster than that). It has no ammonia or peroxide and is a temporary colorant for trying new looks or doing color correction. Hope this helps :)
