YOU don’t have to buy a new wardrobe to achieve a trendy new image for autumn.

In fact, all you need for that cutting edge look is a statement hairstyle.

“As September sweeps in, long beach summer hair sweeps right out,” explains celebrity hairdresser Richard Ward.

“This annual trend is like a hair migration. Women all over the country go for a real departure hair-wise to greet the new season and compliment their wardrobes.”

Avoiding the safe trim option, celebrities are going wild for shock tactics. Be inspired by Pixie Lott’s crop, Katy Perry’s pink tresses and Cheryl Cole’s dirty blonde bob.

New X Factor judge Kelly Rowland recently revealed she has a selection of nicknamed wigs allowing her to change her look as often as her designer heels.

Celebrities have sparked a trend for dazzling with uber-bright hair colours.

Katy Perry picked eye-popping pink, Charlotte Church flaming red, while Sienna Miller and Kate Bosworth were both content with dip-dye streaks of pink and green respectively. Thankfully, rainbow shades aren't the only option.

“Going darker in autumn/winter is common – most women want to reflect the key fashion trends by opting for richer colours, which are denser in tone,” says Ward.

But if you just want a short-lived fling with colour try a non-permanent hair colourant, which last between 6-24 washes, rather than going for the permanent plunge.

And for that really grown-up look, take a look at actress Emma Watson who said ‘Hermione, who?’ once filming for Harry Potter ended and marked the end of the Hogwarts era by going for the chop.

She described her crop transformation as “the most liberating thing ever” and it seems others are demanding the short hair sorcery.

“The super-short crop is the creeper trend of the season and I think this is one that’ll keep on giving,” says Josh Rees Hole, stylist at Urban Retreat.

“Since stars like Emma went for the chop, women have been getting bolder and rocking this Sixties-inspired style for themselves. It’s versatile for any age.”
