I know I sound insane and disgusting but quitting brushing my (fine but dense) hair has been the best thing I’ve done for it. I’ve been able to cut down to like two washes per week (with cleansing conditioner and a hair mask) and even on wash day it looks voluminous, textured, and lived-in instead of flat and greasy… many curly girls do this already but I’m here to suggest it for others as well… try just giving it a little toss upside down and a finger comb instead of brushing and put it up when you sleep to keep knots from forming
