Who has bad roots?Who has two-tone locks?Has someone got locks that can't decide whether they're blonde or brown?

Or do they simply need a top-up?

We've always assumed famous folk had hair pros on hand 24/7 to tend to their every tress need...

But maybe not.

Perhaps famous gals are just like us, and sometimes they get so busy shopping for shoes, or working out in the gym, that they forget to make that monthly hair appointment.

Here's to hoping...

However, if that's not the case, then really, two-tone isn't always a good look. In fact, on some it's a bit of a hair scare.

This lass is a model of note, and we've never seen her locks, well, with a hair out of place.

Mind you, the focus is usually on her bod not her crowning glory.
