Lena Headey Wavy Bob
Lena's dark brown hair is cut to a chin length bob and is full of waves and style as she attends the "300: Rise of an Empire" Los Angeles Premiere.
The ends look choppy and textured as they are free to do what they do in this sassy and fun party 'do. She has a side part and is bang-less while the strands are finger styled to keep the definition of the waves. She has one side tucked behind her ear for an asymmetrical appearance.
And here is full length view which shows how lovely her short hairstyle looks with her long and strapless party dress.
Here is a helpful styling video for your enjoyment.
