Thinking of changing your hair colour? If you want to be ahead of the trends, consider going red. British catwalk queen Lily Cole and Tinseltown star Julianne Moore are great ambassadors of flame-haired hues and it seems many want to copy their look. Superdrug reports sales of red hair colour have doubled in the last three years. Their own ranges include Colour Performance permanent in Burgundy Red, priced £3.29, and Colour Sensations semi-permanent in Deep Mahogany at £2.99.
