Pete Wentz has always been a chameleon when it comes to his hair. The Fall Out Boy bassist has displayed the occasional moment of embracing his natural texture, but on the hole, when his hair has grown longer than a couple inches he’s taken to the flat iron faster than MySpace-era scene kid. His locks have been blond, they’ve been hot pink, they’ve had little wisps of gray peaking through. He’s worn it curly, worn it straight (let’s be real, he’s mostly heated it to a point that surely can’t be healthy for those follicles), and both ways it’s looked good. Suffice it to say, Wentz’s hair has gone through quite a journey through various shapes, lengths, colors, and textures since Fall Out Boy was born in 2001, only to end up right back where he started. Recently Wentz has grown out his mane and gone back to that super-straight style Fall Out Boy fans learned to recognize him for in the mid-aughts, and it is somewhat alarming, but the nostalgia element of the look is appreciated. We should have seen it coming, though, because just last year, the musician started to inch closer and closer to those emo roots of his. In fact, he’s always been a pioneer of emo looks for men—with his guyliner, spiky hairdos, and dark nail polish. Here, a look back at Wentz’s wildest coifs since 2004.
