Wavy but mostly straight.
Every 3 days or so--gets dry otherwise.
I use a conditioner and a leave-in.
I let it air dry and comb it with a big comb, I only use a brush to gather it if I have to put it up (once a week).
Ethnicity? Straight or Curly? How often do you wash it? Hard or soft water? Do you use conditioners? How do you dry it and comb it?
