As for long hair, just condition it a bit, if it's oily wash it a lot, if it's not don't dry it out by washing it too much, comb it every now and again, don't believe hairdressers money spinning scheme that cutting hair makes it grow faster...
I'm a guy and my hair is starting to work it's way past my armpits now >
