If I had to choose between dying my hair a crazy color or  get a tattoo, I would dye a my hair a crazy color because I don't have any good ideas for a tattoo and I feel like if I just walked into a tattoo parlor I would get something that I would really regret. I also have a feeling that my 40 year old self(hopefully I get there) or even my 20 year old self would appreciate my teen self getting a spur of the moment tattoo. Some pros for hair dying; it doesn't last forever( my humiliation only exist in pictures), and all I would need to say is that I was making a fashion statement.
