Banish bad hair days – and the January blues – with a snazzily printed headscarf or bandana. We know Ryan Gosling likes them – after all, Eva Mendes has been snapped on many an occasion (one pictured here) with a length of brightly printed fabric holding back her locks. Accessorised with a hoop earring and/or pair of cat's eye sunglasses, it's a boost of insta-cool. It might not nab you Ryan, but it will defo make you feel happier!
