One Direction might have one of the largest fanbases ever, but we here at HuffPost Style crush on the boyband for one specific reason: Harry Styles’ glorious hair. From the early days of his somewhat-cropped curls to his bad-boy lob (yep, that’s a thing), Styles’ locks just get longer by the year, and we LOVE it.

So, in honor of the heartthrob’s 21st birthday, we’ve compiled a visual timeline of sorts, that shows the evolution of Styles’ mane.

Happy birthday, Harry and have a drink, on us!
