Duffy stars on the festival celebrity hair-o-meter

We're having a field day on the HJi Hair-o-Meter this fortnight, as we give our verdict on the stars who shone or slummed it at Glastonbury and the Isle of Wight Festival.

But what do you think? Are you loving Kelly O's oil-slick style? Do the Sugababes look sweet or sickly?

Join the celebrity hair debate on the My HJi hairdressing forums.

	Hot, hot, hot...
	Duffy looks cute as a button with this sugary-sweet ponytail. Perfectly unkempt and oozing Bardot-style sex appeal, it's an easy, gorgeous and wearable look.
	Proving they can still vamp up the glamour even in the middle of a muddy field, the Sugababes work a trio of tousled tresses - we're loving Heidi Range's effortless updo.
	Alison Goldfrapp's cherubic curls have become her trademark and this quirky style is the perfect fit with her wacky wardrobe and unique brand of electro-pop.
	When it comes to hair, rock chick Kelly Osbourne's never been afraid to take a risk. But this slicked-down look reminds us of Popeye's girlfriend Olive Oyl - hardly a style icon.
	Full marks for trying, Amy, but sticking a few cocktail umbrellas in your beehive isn't enough to hide that hair monstrosity.
	Pixie Geldof's sexy blonde crop won her a Tatler front cover and a wealth of admirers - so why on earth has she stuck on this hideous red fright-wig?
	...Brrrr
