Perhaps a bobby pin or hairspray shortage in Hollywood on Grammy night caused A-list hair pros to skip the updos in favor of long, loose tresses. Famous ladies from Kim Kardashian to Jada Pinkett-Smith rocked manes in a variety of lengths and textures.

Exaggerated Hair Extensions
Ciara went '70s sleek with a centre part and smooth strands that ended right around her derriere with just a touch of curl to add a little romance to the look. Super-svelte Jennifer Hudson also busted out the flatiron to make her strands just as skinny as her new physique. Meanwhile, Jennifer Lopez put her own twist on the look with a little more volume throughout her superlong tresses and brushed her bangs away from her face, giving the look some additional body.

Textured Tresses
Surely giving a small-barrel curling iron a workout, Jada Pinkett-Smith stunned with tight curls that were fluffed into a sexy 'do. Kim Kardashian kept her raven strands long and loose with bombshell waves in a look that was pure Kardashian - sensual and spicy. And Jenna Ushkowitz of "Glee" kept her style light and airy with beachy, scrunchable waves.

Rockin' Redheads
Challenging the age-old adage that it's blondes who have more fun, many of music's finest went bold with bright-red hues. Bringing back her famed crimson hue, Rihanna donned a smooth yet voluminous shoulder-length cut that looked positively ladylike. Hayley Williams of Paramore went even brighter with fire-engine red strands that were styled with short, blunt bangs and curled, face-framing angles. Florence Welch, the ethereal lead of Florence and the Machine, kept her red locks simple with natural-looking waves complemented by some fringe.

One musical lady who bucked the trends at the 2011 Grammy Awards was Nicki Minaj. Check out her leopard 'do!
