Best colour shampoo ever

I have my brown hair lightened and dyed red in the salon. The first time the red (Burgundy red) faded ridiculously fast for a 160 dollar job. The second time the hairdresser gave me this colour refresh shampoo. I put it in, leave it for an hour and rinse it out once a week. And my hair looks freaking awesome. Beautiful colour and so easy to refresh. Get this, you won't regret it.
