Here are the top nine most memorable hair Idols when they were on the show:
Season 1: Kelly Clarkson: Who can forget the original Idol who started this whole frenzy? When she first appeared on the show, we loved Clarkson's shoulder-length, bouncy 'do with chunky highlights. However, "since she's been gone", her hair has been another story!
Season 2: Clay Aiken: Maybe the best bedhead we've seen. Short, choppy layers were lathered up with gobs of gel to create an ultra messy, spiked look for this pop star dad.
Season 3: Jennifer Hudson: The Oscar and Grammy winning performer gave new meaning to the term "big hair" when she and her mega curls stepped on the "Idol" stage.
Season 4: Bo Bice: Rocker, hippie or biker dude? Bo could pass for any one of these with his long, straight strands, bushy eyebrows and make-shift goatee.
Season 6: Jordin Sparks: Jordin's long, flowing curls helped create her signature look. Although, straightening her locks made it appear more like a "battlefield" was going on. We say, "Keep the curls. Why mess with a good thing?"
Season 7: Jason Castro: Put this flower-child in the 1960s and he would have fit right in with his long dreadlocks and hippie style.
Season 8: Adam Lambert: Poofy, punked, edgy, slicked, spiked -- you name it, this modern-day Elvis has worn his hair like it.
Season 9: Crystal Bowersox: While many wanna-be Idols notably changed their looks throughout the show, like it or not, Crystal Bowersox was firm about keeping her dreads.
