Kate Moss, Lily Allen and Cameron Diaz are all trendsetters in their respective careers and eagerly watched for their latest style moves.

Now all have adopted the trend for curly hair, and if these girls are wearing it, there's no doubt that curly hair is in.

But don't panic, despite having been seen sporting a headful of lush curls, bouncy curls - they are not permanent.

In fact, Moss, Allen and Diaz are spearheading the trend for what one magazine has called the '24-hour perm'.

Despite Ashes to Ashes star Keeley Hawes embracing the eye-catching curly do, Grazia magazine has poured cold water on the notion that the dreaded perm is back.

In fact Grazia says women should not be running out to get perms, but instead like the above celebrities we should be embracing the '24-hour perm'.

Moss' transformation owes more to a temporary style change rather than a box of hit or miss perming solution.

But for those a bit frightened of dipping their toe in the perming waters, the 24-hour perm offers the perfect solution.

And with any luck, you might look as great as Kate!
