doesn't matter if it's the face or her hair :P
I found a pic, erased the face though, and replaced it with her head 0:-)
anyway, I found this image: link
lol xD
I think the whole looking like someone is highly subjective. My hair is Ziva-like (wavy-curly, dark brown, sometimes frizzy...). I've also got big, dark eyes and prominent cheekbones. I've been told I look like her a few times, but I can't see any real resemblance.
