Ok so recently I scared half my friends by bleaching and then dyeing my hair alpine green (Directions). But for Halloween me and my housemate Lisa are planning to dress up and go to a club called The Dungeon in Southampton and drag our course mates with us. I'm going to be going as a devil/demon, which will involve me dressing smartly with some small red horns attached to my forehead and Wolf red crazy lens contact lenses. As part of my "costume" I'm planning to dye my hair, though I'm not sure exactly what. I'll have short-ish hair and I want to do something interesting with the colouring/style. Anyone got any suggestions?

Sounds kinda plain but how about Black with dark red streaks.

i'm planning on temporary dreads for my class halloween party

You should keep it green and wear all orange. You'll look like a pumpkin.

Because you have decided a predetermined costume as a demon, my best suggestion is to twist sections of your green hair into spikes that still allow placement of the horn. Also suggest painting your fingernails green to compliment the red lenses and green hair.

An suggestion for another Halloween had doen myself and got compliments. Was with very short hair about 3 inches long had a friend apply orange syling gel to all my hair to completely cover my hair and made it look all orange except a small section on top. The small top section of hair she applied green styling gel and made a curly spike which looked like a stem for the pumpkin. My head being the pumpkin. Then she painted using black styling gel a scary pumpkin face on the back of my head. She was thrilled to let her creativity go in making the face scary. People freaked and remebered me for years to come afterward when i revisited those haunted houses again.

Best regards.
