The whimsical hairstyles spotted in the trailer for the anticipated Oz: The Great and Powerful should be enough to get you excited to see both the film in theaters and the ladies of the film out on the red carpet promoting it. Michelle Williams, Mila Kunis, Rachel Weisz -- what do these Oz stars all have in common? Great hair, of course!

Here are a few leading lady looks from Oz premieres around the world to take note of.

Michelle Williams

On the red carpet for the European premiere of Oz, Michelle sported a deep side part with some chic length. And though she wore a long, flowing wig for her role as Glinda the Good Witch in the film, Michelle is actually growing out her hair in real life! She told E! recently that she has kept her close crop for so long mainly to avoid the "mid-stage" of growing out a shorter cut.

Rachel Weisz

Rachel turned quite a few heads on the recent Golden Globes and Oscars red carpets, and she continues her winning streak here at the Tokyo premiere with her seemingly signature 2013 vintage Hollywood waves and deep side part.

Mila Kunis

Mila is fairly wellknown for hitting the red carpet with understated--but always--chic hair and makeup. (No fuss, you might call it.) But the star rocked a soft but twistedly complicated updo for the Hollywood premiere of Oz, complementing her colorful and classic jewelry, as well as the textures in her gown.  

Salon tip: One thing Mila never disappoints on is her sultry lashes. The next time a client requests a look like Mila’s for a night out, skip the mascara and go for lash extensions.
