The best celebrity hairstyles, cuts and colours of 2010

2010 has been the year of the redhead, with Florence Welch leading the red reign. Mulberry even dedicated a whole fashion show to Flo's look, presenting an army of models in matching wigs.

Rihanna has cemented herself as a bonafide fashionista over the last year, and while we might not have loved all of her transformations, she's encouraged women the world over to embrace brave colours and innovative techniques. 

It's hard to believe that actress Carey has only been on our radar for a year, but ever since her award-winning appearance in An Education, we've been captivated by her gamine look. Although she's grown-out this crop now, it certainly made a splash on all those red carpets she traipsed up this year!

The Saturdays singer is making a name for herself as a real one to watch. Her sexy crop shows that edgy undercuts and super short styles can still be seriously feminine - and she's been one of the most searched-for stars on HJ.

Now that she's back with Jude Law, Sienna seems to have reverted back to the boho-luxe look she made famous when they first dated in the early 00s. Her mane of glossy blonde locks, always artfully dishevelled, remain seriously lustworthy.

A modern day pin-up girl, Katy has a real cartoon character quality to her style. Whether she's rocking bouncy Marilyn curls or that blue wig, Katy combines fun with fashion for a totally unique look.

In the Cheryl vs Dannii style war, we reckon Dannii comes out on top. She constantly reinvents her bob, using colour, clever styling, and texture to create new looks on a weekly basis.

The blonde bombshell has been dubbed the new Jennifer Aniston for her lustrous locks, which are requested in salons across the country every day. Her golden mane combines Serena van der Woodsen's up-town luxe with cool downtown texture and styling.

This has definitely been the year of two-tone hair, and the balayage trend surely has no more dedicated follower than Alexa Chung. Her dip-dyed colour has an effortless feel, which is enhanced through tousled, dishevelled styling.
