I like Natural Instincts because its not bad for your hair. It also washed out in about a month, so if you don't like it you only have to deal with it for that long. The only thing is that it won't lighten your hair; only good if you want to go darker or redder.

well im not sure if there is any Sally's brands in canada but my mom uses the brands from Sally's and they last about four weeks until the roots start to change color

i know for drugstore brand, if you are going blonde, the new loreal dream blonde works really well! i use if to maintain my blonde. it comes with really good conditioning stuff! stay away from the cheap drugstore brands!
