I want to do something new to my hair because I'm bored, but I really love being platinum blonde so don't really want to change the colour, just the style.

As long as you don't look like Nelly Furtado when you're done, you're ok/

I'd do something with layers and side bangs or something, just to make the platinum more of a surprise; I think the color looks really neat when it's in a traditional cut, ie: Nellie McKay's in the weep-fest of PS I Love You - it's just a bob but it gets more mileage with the color.

Nelly Furtardos blonde?

Yeah and now Amy Winehouse has joined the club.

Edited- i read that wrong. I took it as 'Nelly's gone blonde?' Rather then what she meant by it.
My bad.
