Kate Winslet dazzled in her strapless silver Yves Saint Laurent gown at Sunday night's Oscars (07.03.10) and she also impressed with her glamorous hairstyle.

The 'Titanic' actress - who won the Best Actress award at last year's ceremony - looked stunning as her blonde locks tumbled in waves passed her shoulders, giving her the ultimate Hollywood siren look.

London celebrity hairdresser Errol Douglas MBE said of Kate's tresses: "My favourite look of all at the Oscars is Kate Winslet, she looks amazing - elegant, calm, the hair is waved in the right place, backcombed and brushed out - she looks like a siren."

Cameron Diaz went for a similar look to Kate's when it came to hair, and while she still looked stunning, Errol wasn't overwhelmed.

He said: "Cameron's hair looks nice but isn't a show stopper. It's the same style as Kate Winslet's but looser and curlier at the bottom. It's 40s influenced but I'd prefer it combed in to look like a wave rather than left as a curl."

While Sandra Bullock took home the Best Actress honour and was widely praised for her figure-hugging silver sequinned dress, Errol believes her raven locks could have been better.

He told BANG Showbiz: "Sandra's hair could do with more interest with that dress - more texture or movement. It's a bit too flat and straight and doesn't flatter her around the ears! The colour's fantastic, but I'd have done either a low ballerina bun to one side or in the middle; she looks good with her hair scraped back."

As well as long tumbling locks, the up-do was popular on the red carpet at Hollywood's Kodak Theatre and Jennifer Lopez, Victoria Beckham and Diane Kruger all pulled this off to show off their great bone structure.

Eroll - who was awarded an MBE in 2008 for his services to hairdressing - said: "She looks sensational - a great example of when scraped back hair with a simple side parting looks amazing. She's stolen the show!"
