My answer to this question has always been no, there's no such thing as a woman's helmet.
However, now there is. My friend Sarah, Marketing and PR Manager/Schuberth North America has this to say about why many women need a different fitment when it comes to helmets.

I must say that many women in my experience, have needed smaller helmets around the areas she describes, and I found that more than half the time, the female customers that I worked with needed XS-S, rarely M/L and usually the narrower/oval shaped helmets (Shoei/Scorpion/ARAI) tended to work the best. And I definitely saw a lot of women fit the C3W/C3W Pro lines better than any other helmet.
I for one, can't wear the Schuberth C3W. I can only fit the C3W Pro comfortably. The C3 fits me well also. And that's ok, some women will fit one helmet and not another. But I think it's great that Schuberth identified these fit differences and decided to address them.
I think having more options is always a *good* thing. (Yes, even if it's pink!). In the world of women's motorcycle gear, isn't it great to have even more choices? :D
