So you want to die your hair an extreme color that not even Garnier or L'Oreal can't even offer. I got nothing much but a suggestion (so pleaaaase sit and pay attention!). Although extreme colors like pink,teal blue, and purple aren't on the permanent hair color offerings; they are on the mini semi-permanent section. But what brand should you get for that intense hair experience?....(I know this is going to sound a bit cheesy) but why not some SPLAT! I am sure some of you have seen it or heard of it. SPLAT is a brand of semi-permanent hair coloring that has used "extreme" and "rebellious" as part of their motto (although, their website doesn't state since when). I have used their "Blue Envy and have gotten good results. After a month or so, I still am rockin' that "Blue Envy" as you can see. PLUS: they are certified to not test their products on animals (what a savior!). Don't knock it until you try it.
