I am naturally blonde and have dyed my hair semi permanent black, how can i get rid of it??

Preferably diy or cheap! :)
Answer
Ok, first off, why did you dye it black? gross! but you can get the diy kits at walmart for not very anything. you said it was semi perbloke ent, so you could wait till it grows back. do not shave it off or cut it, you will regret it.
