The 80s party starts at eight, and your hair should be the brightest thing in the room: a few passes of this yellow hairspray and it will be. Go for neon streaks or full-on colour for Halloween, a costume party, a school spirit day or a retro dance night.

This yellow hair spray is a temporary hair dye, so the colour is there for the event, not forever. Each can holds 3 oz of bright neon yellow for tips, streaks or a bold all-over shade. It is sold individually, one can at a time, so pick up a few if your whole crew is going yellow.

Then build the outfit around it: neon yellow hoop earrings, an 80s neon fanny pack and neon yellow leg warmers give you a head-to-toe retro style that pops in every photo. Grab your can and get spraying!
