I made a big post above, but everyone washes their hair too much and dries it the fuck out. Your scalp excretes oils to keep your hair pretty good on its own if you just rinse it with water every couple days. You will have a week or so of greasy hair after stopping but your body will quickly adjust to not having detergent rubbed on your head daily and cut down the oil to where it should be pretty quick and your hair will be way better in the end both in health, appearance and ease of styling. When it’s not constantly dried out you’ll find it’s thicker and more malleable for styling.
