As senior colorist at Sally Hershberger's downtown salon, Erin Bogart has seen her share of best-tressed heads and she's sharing her tips for how you can be one! From Rihanna's flirty, dark-to-light locks to Helen Mirren's punky pink strands, the stars have ditched basic brown and boring black to embrace hot new hues—here's who we think is winning the color wars and how you can steal their style…

Best Ombre: Rihanna

Rihanna's hair at the Grammy's was a beautiful example of natural looking beachy ombre. To attempt this color at home, try L'Oreal Paris Feria Wild Ombre. To keep lightened ends from looking brassy, try Clairol Shimmer Lights Shampoo for blonde and platinum.

Best Blonde: Emma Stone

To keep blonde hair healthy looking like Emma Stone's (even after making a color change), make sure to apply deep conditioning treatments weekly. I like Bigen's Protect Repair Deep Conditioner—it makes even the most stressed-out strands feel like silk.

Hot Hair Color Trends for 2013!

Best Red: Jessica Chastain

For Jessica Chastain's Oscar hair color, ask your colorist for golden strawberry highlights subtly woven through a coppery base. Make sure to protect this shade from UV rays—Sally Hershberger Hyper Hydration Super Keratin Spray softens and smoothes hair while protecting hair color from fading.

Best Dark Brown: Mila Kunis

For Mila Kunis' color, ask your colorist for rich espresso brown with tone-on-tone highlights placed just on the ends to keep the look multi-dimensional. For incredible shine like Mila's, try Sally Hershberger Hyper Hydration Super Argan Serum on damp hair before blow drying.

Best Colored: Helen Mirren

Helen Mirren's pink hair at the BAFTA's was so unexpected and fun, and also flattered her skin. To get this look, start with pale blonde and use Manic Panic in cotton candy pink. For a softer, subtler pink, mix in some conditioner to lighten the color and add moisture at the same time.
