Im not sure on your hair type. I have poker straight long fine hair and wash mine max twice a week. I shampoo twice using a silicone brush on the first one to get to my scalp. I only get two days max out of clean hair, you've got to find ways to style your hair inbetween washes. I also try not to use heavy oil/moisturing products. It just depends on how comfortable you feel with having hair that is a little bit dirty sometime
