Remy hair refers to the delicate manufacturing process of the hair. Remy specifically means uni-lateral cuticle direction, in which all follicles point the same direction. Braidiology hair is unprocessed Remy, meaning that after it is cut from the scalp of the donor, it is then lightly cleansed and machine wefted. Machine wefted hair is best for adding thickness and volume. This method also prevents shedding by tightly securing the follicles to the weft.
