Ivy League's Yale Brazilian Body Wave extensions offers a soft and low maintenance that will last 12 - 24 months with the proper care. This texture blends with most hair types, and can be styled and colored with ease. Once straightened, simply wetting the hair will return it to it's wavy/straight texture. Be sure to use parabin-free shampoo and nightly use of a silk bonnet. This will ensure your install lasts long.
