I can tell by the way my hairs feels (gummy, coated) and way too frizzy. My best routine right now is low-pooing every day followed by a condish. Then I apply a leave-in (most of the time) followed by a styling gel (all the time). I've actually been having some great hair days lately since I started using a protein-rich conditioner (Joico K-Pak generic at Sally Beauty). I will rotate this conditioner with some of my many others throughout the week. This made a world of difference as well as the low-pooing every day. Although, I have been able to get some 2nd day hair where I didn't need to do anything else.
