My hair has never been chemically treated. Only used Shampoo and Conditioners, rarely blew dry my hair, mostly wore it up in a bun. Had trimmed about every 5 months. If you notice in the photo there seems to be a wave in the middle of the hair, this is only due to the way that I had stored this hair as I folded it in half, my hair is very straight with only the slightest wave. Once full payment has been received I will immediately ship using your preferred shipping method. If you have any questions feel free to contact me at J.Jalie@hotmail.com
