Needing advice--Debate3

So debate time again, guys. So I wanna to do some crazy stuffs with my body. Like get a piercing. But should I get it on my nose or lip? And which would be less painful? Another thing, I wanna dye my hair again and blue. Right now, I'm letting my red fade, but I had made some mistakes dying it. See, I used splat. But, guess what? I had some problems. The bleach burned my scalp, soooooooooo I ended up going to Sally's afterwards for more bleach. Plus when I dyed my hair red, it felt like paint. Not only that, but most of the color came out instantly when I rinsed my hair. I JUST RINSED IT. And then it turned fussia. That was the first time I colored my hair an abnormal color. I wanna dye it blue as I said, Any tips? And of coarse, me being me, I must make this a debate. People have different preferences to certain brand, so this is easily debatable. And no, I refuse to spend about 40 to 50 dollars to have some salon to do my hair blue. So all products must be to do at home.
Enjoy the debate :)
