Men...how often do you wash your hair

I do it about 3-4 times a year, usually if I've been near a fire/bbq.  I told someone and they were horrified.

You? 

when I wash it then it goes all fluffy and I end up putting loads of product on

without washing I find it easier to manage and it has never been greasy or smelly.  I just don't think you need to wash hair in the way you wash skin.

You really don't need to put shampoo in your hair every day... women certainly don't if tv has taught me anything! Hair benefits from having some natural oil and shampoo removes that.

no?
