Abstract

Clusters of artificial lashes are initially formed using, for example, a hot melt method in which artificial hairs secured to one another following exposure to a heat source. Multiple clusters can then be connected to one another to form a lash fusion. For example, a lash fusion could include three clusters that are connected together in a straight line. Multiple lash fusions can be arranged proximate to one another to form a set. In some embodiments, the multiple lash fusions are positioned such that the form of the set matches the curvature of the tightline of an eyelid. An adhesive can then be applied to the top of each lash fusion in the set, which enables an individual to easily apply the set directly to the underside of the individual'"'"'s natural eyelashes (i.e., near the underside of the eyelid beneath the lash line).

Claims

1. A lash fusion comprising:

multiple clusters of artificial eyelashes that are connected to one another,

wherein each cluster of artificial eyelashes includes at least ten hairs and no more than twenty hairs.

2. The lash fusion of claim 1, further comprising:

an adhesive layer at a top side of at least some of the multiple clusters of artificial eyelashes,

wherein the adhesive layer allows the lash fusion to be applied to an underside of an individual'"'"'s natural eyelashes.

3. The lash fusion of claim 1, wherein the multiple clusters of artificial eyelashes collectively include at least twenty hairs and no more than ninety hairs.

4. The lash fusion of claim 1, wherein the multiple clusters of artificial eyelashes are fused together at one end during a heat seal process to form a straight line of artificial eyelashes.

5. The lash fusion of claim 4, wherein each cluster of the multiple clusters of artificial eyelashes are connected to an adjacent cluster by crisscrossing artificial eyelashes that are fused together at least 1.5 mm and no more than 2.5 mm from a base end that is to be applied to an underside of an individual'"'"'s natural eyelashes.

6. The lash fusion of claim 1, wherein the artificial lashes are comprised of a synthetic material.

7. The lash fusion of claim 6, wherein the synthetic material is acrylic resin, polybutylene terephthalate (PBT), or polyester.

8. The lash fusion of claim 1, wherein the artificial lashes are comprised of a natural material.

9. The lash fusion of claim 8, wherein the natural material is silk or mink hair.

10. A method of manufacturing the lash fusion of claim 1, the method comprising:

forming multiple clusters of artificial lashes;

connecting the multiple clusters to one another to form a lash fusion; and

applying a first adhesive to a top side of the lash fusion that allows the lash fusion to be applied to an underside of an individual'"'"'s natural eyelashes.

11. The method of claim 10, wherein each cluster of the multiple clusters of the artificial lashes is formed by:

fusing multiple artificial lashes to one another along an end by exposing the end of each artificial lash to a first heat source.

12. The method of claim 11, wherein connecting the multiple clusters to one another to form the lash fusion comprises:

overlapping each cluster with an adjacent cluster; and

exposing crisscrossing artificial lashes to a second heat source such that the crisscrossing artificial lashes are fused together at least 1.5 mm and no more than 2.5 mm from a base end that is to be applied to the underside of the individual'"'"'s natural eyelashes.

13. The method of claim 10, wherein the artificial lashes are comprised of a natural material.

14. The method of claim 13, wherein said connecting includes gluing the multiple clusters to one another using a second adhesive.

15. The method of claim 14, further comprising:

exposing the lash fusion to a curing assembly adapted to cure the second adhesive.

16. The method of claim 10, wherein the artificial lashes are comprised of a synthetic material.

17. The method of claim 16, wherein said connecting includes heating the multiple clusters to a temperature sufficient to cause partial melting of at least some artificial lashes in each cluster.

18. The method of claim 10, wherein the lash fusion includes at least three clusters and no more than ten clusters.

19. A method of applying a set of lash extensions to a subject, the method comprising:

obtaining a set of lash extensions that includes multiple lash fusions, each lash fusion including multiple clusters of artificial eyelashes;

grasping each lash fusion of the multiple lash fusions in the set of lash extensions using an applicator;

applying an adhesive to a top side of each lash fusion of the multiple lash fusions;

arranging the set of lash extensions proximate to a tightline of the eyelid of the subject; and

affixing the set of lash extensions to an underside of the natural eyelashes of the subject.

20. The method of claim 19, wherein each cluster of artificial eyelashes includes at least 10 hairs and no more than 20 hairs.

21. The method of claim 20, wherein each lash fusion of the multiple lash fusions includes at least 30 hairs and no more than 90 hairs.

22. The method of claim 21, wherein the set of lash extensions includes at least 150 hairs and no more than 360 hairs.

23. The method of claim 19, wherein artificial eyelashes are distributed along a length of the set of lash extensions at a substantially constant density.

24. The method of claim 19, wherein the adhesive comprises cyanoacrylate.
