Create natural volume and movement with Smart Weft™, a fine machine-tied weft designed for a lightweight feel and seamless blend. Made from 100% Cuticle-Intact Remy Human Hair, it locks in moisture, resists tangling, and stays soft for long-lasting wear. This semi-permanent weft can be applied using beads, a braid & sew method, or custom cut without shedding for a perfect fit.

Hair features:
  • Cuticle-Intact: Each strand is carefully hand-selected to ensure cuticles are facing the same direction
  • 100% Remy Human Hair
  • Fine machine-tied base
  • Zero return hair
  • Cut without shedding for a fully customized fit
  • Reusable up to 3-4x


    • Best for:
    Clients seeking customizable, lightweight extensions with a fine base for natural volume and movement.
    Stylists: Plan on 2-3 hours for a full head application.

    Smart Weft™ offers versatile application techniques including braid & sew or beaded weft. It is also customizable and can be cut to size for a tailored application.
    1. Section the hair using a Pin Tail Comb to create a clean, horizontal parting.
    2. Choose your method: braid, bead, or sew-in with a cap to create a stable foundation.
    3. Position the Smart Weft™ at the base of the sectioned area.
    4. Secure the weft using the chosen technique, ensuring even tension for a natural blend.
    5. Repeat the process across the head until the desired fullness and coverage are achieved.
    Pro Tip: If cutting the weft, be sure to seal the edges to prevent shedding and maintain longevity.
