Take a peek at the best tressed stars (Eva Longoria) and those who needed hair help. By Serena Kappes EVA LONGORIA: BEST The Desperate Housewives star and best actress nominee is elegant with her long, cascading locks. The perfect complement to her tresses: her diamond drop earrings. ANNE HATHAWAY: BEST The Brokeback Mountain actress opts for a delicate updo with an array of tiny braids. JENNY MCCARTHY: WORST Funny lady McCarthy goes for a retro look with a '60s-inspired bouffant, but ends up looking silly instead of sexy. PENELOPE CRUZ: WORST Someone went a little wild with the hairspray: The Spanish siren overwhelms her petite features with her seriously big do. JESSICA ALBA: BEST Alba shines in a loose shoulder-length style with delicate waves and subtle highlights ALANIS MORISSETTE: WORST Farrah Fawcett, anyone? The normally brunette singer (nominated for best song for "Wunderkind" from The Chronicles of Narnia) gives a feathered blonde look a spin, but should've stuck to her roots. JOHNNY DEPP: WORST He's no slave to fashion, but it would have been nice if Depp, nominated for best actor for Charlie and the Chocolate Factory, had run a comb through his unruly locks. KYRA SEDGWICK: BEST The best actress nominee (for The Closer) frames her face with curly tendrils for an utterly feminine effect.
