  • Start with Clean, Dry Hair

    Make sure your hair is completely clean and dry before using THICK FIBER. Avoid using styling products beforehand, as they may create a barrier and reduce the fiber bond.

  • Shake It Right – Sideways, Not Vertical

    To ensure fibers flow smoothly, shake the bottle sideways before opening. Always apply holding the bottle at a 45-degree angle— never vertically - to prevent clumping or blockage.

  • Target Thinning Areas with Precision

    Hold the bottle5cm (1–3 inches)from your scalp and gently shake over thinning areas. Apply gradually and build coverage instead of overloading in one go.

  • Set the Fibers with a Light Spray

    Once the fibers are in place, gently pat them down and apply alight-hold hair spray from about 8–10cm away. This locks them in for a longer-lasting finish without stiffness.
