Divas from the past and future (Queen of colour)

The trend for coloured hair has been gathering momentum for the past couple of years, but after everyone from rock chicks, pop stars to models experimenting with dyed, dipped, sprayed and streaked looks, it's clear coloured hair has been getting bigger. Debbie Harry of course was rocking the look long before any of us. But a favourite celebrity has taken the crown for best coloured hair. Katy Perry! Katy is constantly changing her hair color from black to blond to pink, and seemingly every shade in between and always rocks it.
