What not to do with my hair so it'll grow?

Okay I know to like not use heated things on it (straightener, curling iron, blow dryer, etc), don't put it in a bun, don't wash it everyday. What other things should I not do to my hair so it will grow faster? And things I should do to help it stay healthy and keep the oils in it that are needed. (things I can do at home without using any money or having to go to a salon except for getting trims regularly)
