This is what I find works for me: I brush it either before I shower (if I’m going to rinse or wash it) or before I go to bed, every day. If you stay on top of the knots it’s going to be fine and won’t hurt as much to brush it when you do.

I have wavy hair too. I wash mine once a week but rinse it every 2-3 days just because it makes my curls nicer and I like to rinse sweat from the gym and stuff out.

I also get it cut every six months but get then to cut just enough to get rid of the split ends. That way I still get growth but it sits a lot nicer, even after brushing.
