i find that this really only works if your hair is a lighter colour. but if you reapply it every few weeks the colours really stay on well over the time it says it'll last. it also makes your hair really smooth. a good resource when wanting a quick change for a few weeks

I was really skeptical about these products when they first came out. They were so popular and so hard to find, so when I actually did find a colour that I liked I snatched it up quick so I could see what all the fuss was about. This stuff is actually pretty cool. When you're looking for a little pick-me-up or just some fun, but you don't want anything permanent, then you should try this! It's so simple and easy to use. And, unlike most hair dyes, it doesn't have an overpowering smell to it. It washes out naturally and it's as easy as putting mouse in your hair. If you want to change your colour for awhile, or even for Halloween, you should buy this product. It lasts about two weeks, or less, depending on how often you wash your hair. Just remember, the darker your hair, the harder it is for any of those lighter shades to show.
