Brunettes have more fun! Tulisa switches her peroxide blonde locks for a darker 'do as she parties in Ibiza

When it comes to her hair, she seems to change her mind like the wind.
And now X Factor judge Tulisa Contostavlos has altered her appearance yet again – opting to go back to her brunette roots.
Just a few months after Tulisa dyed her hair a brash peroxide blonde, the Live It Up star has proven that blondes do not have more fun – deciding to ditch the bleach in favour of a more classy brunette shade.

New hair: Tulisa partied hard in Ibiza - and posted this picture of her on a night out on Twitter

For many years during her stint in N-Dubz, Tulisa highlighted her naturally brunette hair to a much lighter shade of blonde.
The singer appeared on The X Factor last night to make her final decisions on who she would take through to the live shows.
She is mentoring the girls category this year and faces stiff competition from fellow judges Gary Barlow, Louis Walsh and former Pussycat Doll Nicole Scherzinger who joined the panel this year.
