How my hair should be cut

I looked around online a little but it all seemed female-focussed. I am looking for websites that help guys figure out how they should cut (and style, I suppose) their hair.

Looks like face shape and so on has something to do with this.

What are some good websites that could help a guy through this?

Improving the quality of my googling has improved the quality of my results somewhat. Links still welcome, though.
