Celebrities have as many 'dos as they have hairs on their heads -- just ask Katy, or Miley, or Beyonce or... well, you get the picture. They're an endless source of inspiration for our own lids, so we bring you 21 celebrity hairstyle how-tos -- a style for each day leading up to summer (plus one more for good measure) -- including everything from Kim Kardashian's trademark bun to Rihanna's '70s-inspired waves.
Some of these styles are straightforward, like Gwyneth Paltrow's pencil-straight tresses, while others require a bit more patience, like Scarlett Johansson's milkmaid braid. Some updos will look right at home on the red carpet, while every girl can tousle up some loose waves any day of the week.
