I have dry ends and greasy roots, I have to poo about once a week or my roots and scalp get totally grody. I'll dilute a small bit sulfate shampoo with water and concentrate the cleaning at my roots, and rinse it out quickly. I condition my roots with a lighter conditioner like SN Aloe, and focus the thicker conditioners on the length of my hair and especially the ends. This seems to be what is working best for me right now.
