If you are / were one of the guys and gals with the best hair in your high school, then you  probably had other students asking where you had your cuts done, and which shampoo you've been using to lather up. We bet these pop stars have the same questions pitched their way 'till this very day, as they've got some of the best hair in the music biz. But whose locks reign supreme in your opinion?

Check out some of the most eye-catching, signature hairdos in pop below. We've got nominees like Adam Lambert, who has been rocking a sky-high, two-toned spikey 'do, and Bruno Mars, whose lil afro makes us smile big. Ed Sheeran is nominated for that amazing, fiery red, shaggy cut he looks so adorable with, and Hayley Williams of Paramore  is also nominated for her edgy, newly-dyed, split-down-the-middle hairstyle of pink and orange.

Further down, you can see Jessie J, who just shaved her head for Red Nose Day and is looking ab fab with her bleach blond buzz cut. You'll also see Katy Perry's glossy, raven-hued hair, as well as pompadour-esque 'dos from Justin Bieber, Macklemore, Miguel, Miley Cyrus, Pink and One Direction member Zayn Malik, who all have their own very unique way of styling dem locks.

Finally, there's Rihanna, who drops a lot of dough to make her lustrous hair look so beautiful all the time (look at the length she's been wearing as of late -- so pretty, RiRi!), and Taylor Swift, whose gorgeous and healthy blond locks switch between curly and straight with ease.
