Definitely in the US there is a perception that more Russians than not have blond hair. I read an article recently about women in Russia selling their hair for wigs (from the NY Times: http://www.nytimes.com/2010/11/22/business/global/22blond.html). Though maybe this is more about Eastern Europe than Russia itself.

I agree about England being full of blonds. I used to refer to it as "Mascara Nation" when I first went there.
