The Grammy Awards 2015 saw some impressive hair transformations including Katy Perry's newly purple hair and Rita Ora's pixie crop. Then, of course, there was Gaga's grey hair and Iggy's impressive sculptural braids. On the flipside, the make-up was kept pretty classic with a slew of smoky eyes and the only bold lip of note coming from Jessie J but even that was a sophisticated plum shade.
