Cuticle hair is referred to hair that has the cuticle intact and all cuticles going in the same direction! The cuticle provides a natural luster and sheen to the hair. It is what prevents the hair from tangling. ONYC Luxury Ultima and Golden-Collection are all product of Full Cuticle Virgin Hair, which means each strand of hair has its cuticle intact. Cuticle hair is the most expensive hair; don’t be fooled with Companies that claim to sell you full cuticle hair for a fraction. It is most likely mixed with non-cuticle hair.
