Jewish wigs from Guloor are only made of 100% human virgin hair.
The raw hair material for virgin hair is braids, which are directly cut from donors. The braids are only washed and double drawn, and then made into wigs. During the whole production, the hair is not chemical treated, so the virgin hair keeps intact cuticles, and for sure all cuticles are going in the same direction. Since there is no damage on virgin hair, the virgin hair lasts the longest.
