Naturally curly, straight, curling iron, wet, dry, conditioning treatments, oils, leave-in conditioners DOES NOT MATTER they have RELENTLESS KNOTS! I will brush out my whole head move an inch and come back, whole head is knotted again! I go to sleep with it wrapped completely knotted AGAIN! Go to sleep with it braided, i take the braids out and it’s completely knotted STILL!! This is NOT WORTH over $200!!!
