One Pack of Curvy Betty: for creating braid-less tracks on thick hair. Comes with eight 13″ pieces. Apply secure tracks before sewing in wefts of hair with Curvy Betty. Keeps braid-less tracks together safely as one unit. When they grow out, they are comfortable and stay together until it is time to remove them. Other braid-less track methods can add unnecessary stress onto the scalp because they grow out separately and ultimately pull the natural hair causing damage to the scalp.
