I have naturally straight hair with a very slight wave in some sections but I often do heatless curls which give me a nice wavy effect. My hair is long and while it looks great on the first day, I'd like to be able to get away with a second day out of it but it gets so tatty by the end of the day I don't feel like I can get away without brushing it which obviously creates a big frizzy effect. How do others manage this and is there a way to detangle properly so I can get another day out of it even in a ponytail?
