In a nod to 90s grunge, this season's undone hair takes its inspiration from those situations a girl would normally associate with bad hair days – like the second day at a festival or the 'walk of shame' the morning after the night before.
At Marc Jacobs, luxurious furs were contrasted with dishevelled just-got-out-of-bed hair. At Alberta Ferretti, windswept fringes gave otherwise elegant chignons an unkempt twist.
On the Alexander Wang and Jonathan Saunders catwalks, roots were deliberately flattened.
From centre-parted waves to choppy shoulder-length bobs and eye-skimming fringes, chameleon Kate has been through every look in the book, but her dos never look too 'done'. The mistress of the no-style style, Kate has no interest in looking like she's just stepped out of a salon (we'll overlook the fact that close friend and top stylist, James Brown, is never far from her side). Effortless. Cool.
There is a subtle difference between matte hair and dull hair. One is achieved by experimenting with matte clays and texturising products (and looks cool). The other is achieved by not washing your hair (and doesn't).
For tousled, waves spritz damp hair with a surf spray then grab handfuls and scrunch away. Give poker straight hair a helping hind by plaiting it before you go to bed.
To create a carefree up-do like those seen at Alberta Ferretti, leave a few strands out at the front of your hair before pinning it up. Create a low parting then sweep it across your forehead and hold in place with spray.
Second-day hair is ideal for this trend. If yours is prone to oiliness, use a dry shampoo to absorb oil without losing texture.
