Hairstyle heroes: battle of the x factor judges

From Dannii's deceptively versatile bob and Cheryl's updos to Kelly's wigs and Tulisa's colour, there's no shortage of hairstyles to talk about on The X Factor judging panel. 

We asked Blue Greeves from Burlingtons, Newcastle to give her opinion on the judges past and present.

"The X Factor was a major turning point for Dannii and it literally revived her career. 

"In the past she hadn't made much of an impact with her image but on the show her clothes, make-up and hair always worked brilliantly. One week she would have a perfectly straight sharp bob, then the next she'd have a side-chignon or a big quiff. 

"Dannii showed the nation that short hair can be as versatile as long hair and, with a little imagination and smart hair pieces, she proved anything is possible." 

"Cheryl used The X Factor as a catalyst to transform her style, and her hair was as much a talking point every week as anything else. Overall, there were very few times Cheryl got it wrong, and I loved the way that one week she would have long tumbling curls, then the next a cute boho-inspired updo. 

"We had clients coming into the salon asking for Cheryl-inspired creations after the shows each weekend. Cheryl will always be an icon, especially for salons like ours in the North East." 

"There's no doubt that Kelly is stunning, but her hair has been very much the same so far and 

I would love to see her experiment a little more by pulling the fringe off her face or wearing a sleek updo. 

"Her fringe frames her face perfectly and is a great example of how a cut can enhance your features, but I would like to see her with some different looks other than just poker-straight or waves." 

"What shines through with Tulisa is that she has such a strong personality - we almost expect her to have a bit of an edgy wardrobe and hair style to mirror her quirky persona. 

"Her hair is a little less 'done' than the fellow judges' but it really suits her. She has lovely long, glossy hair and the strong dark colour suits her. However, she could carry off a lighter shade, which would soften her looks.

"She's experimented with an array of styles and is a real chameleon - definitely one to watch." 

"Overall, I think the most stylish judge of them all is Tulisa. 

"The great appeal of Tulisa is that she is not too polished and her look is still a little rough around the edges, which makes her a lot more appealing. She doesn't let her young age stop her from speaking her mind and making a statement, both in the style stakes and vocally. 

"She will be here for a long time to come and the younger generation will aspire to be like her."
