Something that doesn't relate to 'am I pregnant' and sex for a change....

Simple question. How do you keep your hair nice and healthy? Shiny, prevent split ends, protect from damage, reduce hair loss, that kind of thing.

And how often do you need to wash your hair? Personally, I have longer hair that's naturally curly, so to the curly haired, do you try and tame it or let it go wild? Do you find you need to wash it as much as maybe a straight haired person does?
