The term "Yaki" refers to the texture of the hair. Our Yaki Straight hair matches the rhythm of natural hair that's been pressed straight or freshly relaxed. This hair is lightweight, yet full of body and flowy movement to mimic afro-caribbean hair textures. This hair can be heat-styled and dyed, but treat them like your own hair. To protect their longevity, limit heat use and always apply a heat protectant.
