Rainbow hair has been a hot trend this summer with the A-list with everyone from Kate Bosworth to Katy Perry getting in on the act. If you haven't tried the trend, why not give it a go this weekend, before the autumn ushers in a new hair mood.
Colour Extreme temporary hair spray, £4.07 (boots.com), comes in an array of bold shades (including celebrity favourites green and pink) and washes out easily so its low commitment.
ELLE magazine's fashion interns Elizabeth and Caitlin agreed to be guinea pigs for me and to great effect, proving this look works just as well on short hair as it does on long.
It's the perfect solution for festival hair (it's Bestival this weekend, FYI) or a great way to change your hair for one night only.
