I know American Idol is a singing competition (der), but who votes just on voices? Impossible. It's more about who's got good hair, and who's got bad hair (like all these freaky people, rivaling Sanjaya's insane mohawk). Makeup-wise, some of the ladies were never taught to avoid these major makeup no-nos. Okay, okay, I'll admit that they're not all bad. Katharine Mcphee did get a Neutrogena (see their best and worst-rated products here) contract post-Idol, after all.

So, what do you think of my best/worst gallery here?

Best: Syesha Mercado

Love her playful natural curls and age-appropriate makeup.

Worst: Amanda Overmyer

I'm all for a rock and roll look, but this is taking it to the extreme.

Best: Ace Young

Great hair. Great smile. Need I say more?

Worst: Nikki McKibbin

Ouch! This girl needs color correction and teeth whitening stat.

Best: Katharine McPhee

Glowing skin and gorgeous cheekbones make Katharine sparkle.

Worst: Elliot Yamin

Oh those teeth and ears! It's no wonder post-Idol he grew out his curls and got Veneers.
