Both women are far more attractive with long hair, however i think Hayden's bob does looks better but the blonde helps with that...hair colour is a must!

Based on the two photos, I tend to lean toward the star of "Heroes" over the youngest of the "Desperate Housewives" in regards to shorter bobs. Both Hayden & Eva are more attractive with longer hair, and I hope both are strictly summer styles ONLY.

I think they both look better with long hair. The short hair...isn't flattering to either!

I like it better on Hayden, her hair is fuller, I think Eva looks pretty with long hair.

It would be really hard to say either one looks bad, I just happen to like Hayden's cut better...

Hayden has a wide face, therefore she looks better with longer hair. She's still adorable, but it works better for Eva.
