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 method comprising:

obtaining a set of clusters of artificial eyelashes that form a set of lash fusions that are connected to a base in order to form a set of lash extensions, wherein each cluster of the set of clusters is heat fused at its root, wherein the set of clusters is further heat fused adjacent to each other to form the base;

grasping the set of lash fusions via an applicator;

applying an adhesive to a top side of the set of lash fusions;

arranging the set of lash extensions via the applicator proximate to a proximate end portion of only an underside of a natural upper eyelash of a subject such that the base extends proximate to the natural upper eyelash; and

affixing the set of lash extensions only to the underside of the natural upper eyelash of the subject such that the top side adheres to the underside via the adhesive.

2. The method of claim 1, wherein at least one cluster of the set of clusters of artificial eyelashes includes at least 10 hairs and no more than 20 hairs.

3. The method of claim 2, wherein at least one lash fusion of the set of lash fusions includes at least 30 hairs and no more than 90 hairs.

4. The method of claim 3, wherein the set of lash extensions includes at least 150 hairs and no more than 360 hairs.

5. The method of claim 1, wherein the set of lash fusions is distributed along the base at a substantially constant density.

6. The method of claim 1, wherein the adhesive comprises cyanoacrylate.

7. Method of claim 1, wherein the adhesive is applied directly to the top side of the set of lash fusions.

8. Method of claim 1, wherein the adhesive is applied indirectly to the top side of the set of lash fusions.

9. A method comprising:

causing a user to access a set of clusters of fibers that form a set of lash fusions that are connected to a base in order to form a set of lash extensions, wherein the user has a natural upper eyelash having an underside with a proximate end portion, wherein the set of lash fusions has a top side, wherein the lash fusions extend lateral to the base, wherein each cluster of the set of clusters of fibers is heat fused at its root, wherein the set of clusters of fibers is further heat fused adjacent to each other to form the base;

causing the user to apply an adhesive to at least one of the top side or the underside;

causing the user to position the set of lash extensions adjacent to the proximate end portion such that the base extends adjacent to the natural upper eyelash; and

causing the set of lash extensions to be removably coupled to the underside such that the top side adheres to the underside via the adhesive.

10. The method of claim 9, wherein the set of clusters of fibers is fused via a heat seal process.

11. The method of claim 9, wherein the set of clusters of fibers is formed via fusing a plurality of fibers to one another along a plurality of ends thereof by exposing the ends to a heat source.

12. The method of claim 9, wherein the set of clusters of fibers includes a plurality of adjacent clusters that overlap each other.

13. The method of claim 9, wherein the set of clusters of fibers is formed via heating a plurality of clusters of fibers to a temperature that causes at least a partial melting of at least some fibers in the clusters.

14. The method of claim 9, wherein the user is caused to apply the adhesive to the top side.

15. The method of claim 9, wherein the user is caused to apply the adhesive to the underside.

16. The method of claim 9, wherein the user is caused to apply the adhesive directly to at least one of the top side or the underside.

17. The method of claim 9, wherein the user is caused to apply the adhesive indirectly to at least one of the top side or the underside.

18. A method comprising:

causing a user to access a set of clusters of fibers that form a set of lash fusions that define a base in order to form a set of lash extensions, wherein the user has a natural upper eyelash having an underside with a proximate end portion, wherein the set of lash fusions has a top side, wherein the lash fusions extend lateral to the base, wherein each cluster of the set of clusters of fibers is heat fused at its root, wherein the set of clusters of fibers is further heat fused adjacent to each other to form the base;

causing the user to apply an adhesive to at least one of the top side or the underside;

causing the user to position the set of lash extensions adjacent to the proximate end portion such that the base extends adjacent to the natural upper eyelash; and

causing the set of lash extensions to be removably coupled to the underside such that the top side adheres to the underside via the adhesive.

19. The method of claim 18, wherein the user is caused to apply the adhesive directly to at least one of the top side or the underside.

20. The method of claim 18, wherein the user is caused to apply the adhesive indirectly to at least one of the top side or the underside.

21. The method of claim 18, wherein the set of clusters of fibers is fused via a heat seal process.

22. The method of claim 18, wherein the set of clusters of fibers is formed via heating a plurality of clusters of fibers to a temperature that causes at least a partial melting of at least some fibers in the clusters.
