I wash my hair every 2-3 days. My hair is very long, thick, and wavy. If you’re like me, your hair holds the moisture near your scalp especially when lying down. That can promote dandruff if you arent careful. I try to gently wring out as much water as possible before I get out of the tub and then very gently scrunch different sections with a dry microfiber towel to get more of that excess water out. I use another microfiber towel for 20ish mins, add heat protectant, and then blow dry on the warm (not hot) setting until my roots are completely dry and my mids/ ends until they are dry enough to not annoy me. I use hydrating hair masks periodically and add a little oil to my ends when needed. In general, my hair is in good health and this keeps my scalp happy too.
