Okay, so what the hair's advantages and disadvantages. First and foremost, the hair arrived quite quickly. That was fantastic. The fragrance of the hair was real. It required two washes. My hairdresser curled (tried) it after the installation. The curls don, if I may say so.t at all stay inside. I want the curls will continue. It's sheds as well. However, the length is ideal, and the color is stunning. If I were to purchase this brand again, I would just purchase straight hair; I wouldn't purchase body wave.
