  • a plastic matrix is formed, in which the individual hairs are embedded and anchored with their upper ends.
  • the plastic matrix is covered with a matt and translucent cover layer so that the plastic matrix of the device remains visually unobtrusive.
  • the adhesive tape formed as a carrier tape has on its the plastic matrix, in which the hair is anchored, the back facing away an adhesive layer for sticking to the natural hair of the wearer. This adhesive layer, like the plastic matrix, extends over the entire surface of the carrier tape.
  • the plastic matrix is an optical disadvantage of the known hair extension device. That is, it falls as soon as it is exposed in an undesirable manner.
  • a hair extension which has hairs secured at their upper ends in a solidified polymer with the ends of the hair retained in the polymer over a portion of the hair length.
  • the solidified polymer is attached to a substrate on its backside.
  • the substrate may be another solidified polymer.
  • the width of the substrate is larger in a main direction of the hair than the width of the solidified polymer in which the hairs are fixed.
  • the larger width of the substrate facilitates attachment of the hair extension to the natural hair of its wearer.
  • the anchoring of the hair only over a small length in the solidified polymer and the correspondingly smaller surface of the polymer are less noticeable. However, there is a high probability that the unnatural-looking substrate will shine through.
  • the substrate is formed simultaneously with the polymer, wherein the further polymer of the substrate can adhere to and between the hair. So that the substrate is not directly outward shining through, it is covered below the narrower solidified polymer with hairs that are anchored only in the narrower solidified polymer and run underneath freely across the substrate.
