I NEED TO DYE MY HAIR NOW

UGH! so I'm totally abt to go through a whole identity crisis (ToT) so basically I haven't dyed my hair in a few months I need it dyed now especially bc school is around the corner and I can't go to school looking like a wrecked out scene emo girl ( ＞Д＜；) but I am so sick of my hair being this redish brown color!!! like it's cute and all but I js don't like it on me!! I need my hair purple bc last time was an absolute fail obvi -.- I didn't get the right measurements for my developer for the dye so my hair came out looking absolute trash (　ＴДＴ) hopefully I can't get hair dye this week and a new measuring bowl!! wish my luck cuties X-<
