Commonly Asked Questions

What kind of cable machinery you need?
  • Is two strand twist better than normal twist?

    Two-Strand Twists Are One of the Easiest—and Healthiest ...
    Two-strand twists are an easy, beautiful protective style with an added bonus: They can help lock in moisture. While flat twists work well on different textures, two-strand twists generally work better on completely natural hair as the ends usually hold together without additional help from bands or barrettes.
  • What is the difference between single twist and double twist bunchers?

    A The basic difference between a single twist buncher, strander or cabler is that a single twist machine gives one 360 degree twist in the wire or cable for one 360 degree turn of the bows. A double twist machine gives two 360 degree twists in the wire or cable for every 360 degree turn of the bows.
