Recently starting co-washing after doing one last no 'cones, sulphate wash. Think i'm about 2 weeks in. Anyway i'm having a problem. Everytime I try to wash my hair, its really hard to do it. Takes me like 45mins-1hr which I know isn't right. Basically the problem is, when I go to wash my hair, it feels really dry and hard to get conditioner through. So it ends up with me using up tons of conditioner. It's really annoying because I'm loving the results. My hair is less frizzy, less flat, and more defined and voluminous. I'm using Tresemme Naturals, and nearly used up half the bottle already. Can anyone help me?
