I feel for her hairdresser. It seems it's not easy to style that hair. Most of the time it just looks like someone desperately attempted something with a brush, a hairdryer and a bunch of hairspray with varying results.
I think her hairdresser is the problem here. We have seen her in a few nice updos, so it's obviously possible for her hair to look decent, but yet she still looks like a mess most of the time. She should fire Marre and let someone who actually knows what they are doing style her hair instead.
