I've been using this for years and it's by far the best semi-permanent hair dye out there in my opinion. I've tried Manic Panic, directions, punky colour and other ones but they never gave me the same result as this dye. First of all, the price is great, and you can easily order it off of ebay or amazon. All their dyes are super pigmented and I only have to mix a few drops of dye with my conditioner to get a nice deep magenta colour. I always mix it up, put it in my hair and then covered with a shower cap leave it in for about an hour and rinse with cold hair as a conditioning colour refresher. When you're dyeing your hair for the first time you will most likely have to bleach your hair first and use a bit more dye to get even coverage, but after that you really only need a small amount of dye diluted with conditioner to keep the colour fresh. This means one small bottle will last you for a while and it won't cost you an arm and a leg to keep up your fun colour!
