Ventilated hair extension wefts

A kit comprising:

• A hair extension weft comprising:
• a polyurethane strip extending along a longitudinal axis and comprising a first extending between first ends of the first and second longitudinal edges and a second transverse edge, opposite the first transverse edge and extending between second ends of the first and second longitudinal edges, wherein the longitudinal axis divides the polyurethane strip into equal top and bottom halves;
• a first rectangular mesh secured to the top half of the polyurethane strip, a first gap disposed between the first longitudinal edge of the polyurethane strip and a top edge of the first rectangular mesh, a second gap disposed between the first transverse edge of the polyurethane strip and a first lateral edge of the first rectangular mesh, and a third gap disposed between the second transverse edge of the polyurethane strip and a second lateral edge of the first rectangular mesh;
• a second rectangular mesh parallel to the first mesh, and secured to the bottom half of the polyurethane strip, a fourth gap disposed between the second longitudinal edge of the polyurethane strip and a bottom edge of the second rectangular mesh, a fifth cap disposed between the first transverse edge of the polyurethane strip and a first lateral edge of the second rectangular mesh, and a sixth gap disposed between the second transversed edge of the polyurethane strip and a second lateral edge of the second rectangular mesh;
• a seventh gap disposed between a bottom edge of the first rectangular mesh and a top edge of the second rectangular mesh;
• a plurality of apertures uniformly spaced from each other and disposed within the seventh gap, along the longitudinal axis of the polyurethane strip, wherein the plurality of apertures disposed along the longitudinal axis are the only apertures provided on the hair extension weft;
• wherein the first, fourth, and seventh gaps are each 0.5 cm, and the second and third gaps are 1 inch;
• the first mesh has a length of 8 inches and a height of 0.5 cm and the polyurethane strip has a length of 10 inches and a height of 1 inch;
• and
• wherein the first and second rectangular meshes comprise a plurality of extension hairs attached thereto such that the extension hairs of the first rectangular mesh extend toward and beyond the first longitudinal edge and the plurality of extension hairs of the second rectangular mesh extend toward and beyond the second longitudinal edge;
• and
• a plurality of microbeads, wherein each of the plurality of microbeads comprises an inner surface including a lining of silicone;
• and
• a plurality of anchors, each anchor of the plurality of anchors being-configured to be clamped under heat.

A hair extension weft comprising consisting of:

• a polyurethane strip extending along a longitudinal axis and comprising a first longitudinal edge, a second opposing longitudinal edge, a first transverse edge extending between first ends of the first and second longitudinal edges and a second transverse edge, opposite the first transverse edge extending between second ends of the first and second longitudinal edges, wherein the longitudinal axis divides the polyurethane strip into equal top half and a bottom halves half;
• a first rectangular mesh arranged in secured to longitudinal direction along the top half of the polyurethane strip, a first gap disposed between the first longitudinal edge of the polyurethane strip and a top edge of the first rectangular mesh, a second gap disposed between the first transverse edge of the polyurethane strip and a first lateral edge of the first rectangular mesh and a third gap disposed between the second transverse edge of the polyurethane strip and a second lateral edge of the first rectangular mesh;
• a second rectangular mesh parallel to the first mesh, and arranged in secured to the longitudinal direction along the bottom half of the polyurethane strip, a fourth gap disposed between the second longitudinal edge of the polyurethane strip and a bottom edge of the second rectangular mesh a fifth gap disposed between the first transverse edge of the pol urethane strip and a first lateral edge of the second rectangular mesh and a sixth cap disposed between the second transverse edge of the polyurethane strip and a second lateral edge of the second rectangular mesh;
• and
• a seventh gap disposed between a bottom edge of the first rectangular mesh and a top edge of the second rectangular mesh, and
• wherein the first, fourth, and seventh gap are equal in size, and the second and third gaps are equal in size, and the first, fourth and seventh gaps are different in size than the second and third gaps;
• and
• a plurality of apertures uniformly spaced from each other and disposed within the seventh gap, along the longitudinal axis of the polyurethane strip, wherein the plurality of apertures disposed along the longitudinal axis are the only apertures provided on the hair extension weft;
• and
• the first and second rectangular meshes comprise a plurality of extension hairs attached thereto such that the extension hairs of the first rectangular mesh extend toward and beyond the first longitudinal edge and the plurality of extension hairs of the second rectangular mesh extend toward and beyond the second longitudinal edge.
