The secret reasons why Dannii's hair 'dos have the X-Factor

Who'd know there's a sleek, short bob underneath all that body and movement? A couple of quick tricks help give Dannii maximum versatility with her hair
Dannii Minogue has really upped the ante in the style wars on this year’s X-Factor – but has one in-built advantage.

Apparently, because of Cheryl’s L’Oreal contract, she is tied to keeping her hair long and on display as much as possible, while Dannii’s free to experiment with a different style every week.

And, boy, does she have one inventive hairdresser. Who knew you could squeeze so many looks out of one style – and that a short bob could be so versatile?

Dannii's hair is done by Christian Vermaak, who says "everyone I know is asking for the bob" – a style that was pioneered in the 1960s by super stylist Vidal Sassoon – and which he’s tipping to be the look for 2010.

He recommends Batiste dry shampoo – available from Boots and Superdrug – to give hair ‘oomph’, which is essential when you’re dressing hair up.

The powder coats hair, mainly to absorb grease, but in doing so also adds thickness which makes it easier to shape and keep in place.

Make sure you use it with a shine spray spritzed over the outside of the style when you’ve finished, though, as dry shampoo is incredibly dulling. Hairspray is also great for adding shine, as well as hold.

Christian often crimps Dannii’s hair, which is also great for thickening and building shape. Crimp hair in the direction in which you’ll be dressing it, which makes it easier to direct and keep in place.

For a Dannii-style quiff, loosely pull crimped hair backwards, inserting grips along the way – they get ‘lost’ in the mass of crimping so you can use them more liberally than on normal hair – but letting it hang loose at the ends.

Then finish with hairspray for shine – light isn’t able to bounce off crinkly hair as well as off straight hair so it will look dull, but shine spray often contains oil which may cause the crimping to flatten.
