    "1. An artificial lash extension system comprising: a plurality of lash extensions designed to attach adjacent to one another at an underside of natural lashes, each of the plurality of lash extensions comprising: a plurality of clusters of artificial hairs, each of the plurality of clusters comprising at least two artificial hairs; and a base from which the at least two artificial hairs of each of the plurality of clusters protrude, wherein at least some of the artificial hairs are connected to one another at a respective part of the base by at least an application of heat.",
    "2. The artificial lash extension system of claim 1, wherein the at least some of the artificial hairs that are connected to one another at the respective part of the base by at least the application of heat correspond to at least one of the plurality of clusters.",
    "3. The artificial lash extension system of claim 1, wherein the base of each of the plurality of lash extensions is formed by at least the application of heat.",
    "4. The artificial lash extension system of claim 3, wherein the plurality of clusters are connected together by at least the application of heat.",
    "5. The artificial lash extension system of claim 1, wherein the at least two artificial hairs comprise a synthetic material.",
    "6. The artificial lash extension system of claim 5, wherein the at least two artificial hairs comprise polybutylene terephthalate (PBT).",
    "7. The artificial lash extension system of claim 5, wherein the at least two artificial hairs comprise polyester.",

    "9. The artificial lash extension system of claim 1, wherein an artificial hair of a first cluster of the plurality of clusters crisscrosses another artificial hair of the first cluster.",
    "10. The artificial lash extension system of claim 1, wherein the application of heat facilitates at least a partial melting of the at least some of the artificial hairs that are connected to one another at the respective part of the base.",
    "11. The artificial lash extension system of claim 1, wherein the application of heat comprises heat sealing.",
    "12. The artificial lash extension system of claim 1, wherein the application of heat comprises heat fusing.",
    "13. The artificial lash extension system of claim 1, wherein each of the plurality of lash extensions is further formed by an application of an adhesive.",
    "14. The artificial lash extension system of claim 13, wherein the plurality of clusters are connected together by at least the application of the adhesive.",
    "15. The artificial lash extension system of claim 1, wherein each of the plurality of clusters is connected to the base.",
    "16. The artificial lash extension system of claim 15, wherein one or more of the plurality of clusters is directly connected to an adjacent one of the plurality of clusters at the base.",
    "17. The artificial lash extension system of claim 15, wherein one or more of the plurality of clusters is indirectly connected to an adjacent one or more of the plurality of clusters.",
    "18. The artificial lash extension system of claim 1, wherein a thickness of the base ranges between 0.05 millimeters (mm) and 0.15 mm inclusive.",

  "description_excerpt": "Various embodiments concern artificial eyelashes and, more specifically, clusters of artificial eyelash extensions that can be applied to the underside of an individual's natural eyelashes.\n\nEyelash extensions have conventionally been used to enhance the length, thickness, and fullness of natural eyelashes. Eyelash extensions, however, must be applied to an individual's natural eyelashes one by one to avoid having the eyelash extensions stick together. Consequently, lash extension services can cost hundreds of dollars depending on the type and number of lashes used, the skill of the cosmetician, and the venue where the eyelash extensions are applied. It usually takes an experienced cosmetician one to two hours to attach a full set of eyelash extensions.\n\nClusters of artificial lashes have conventionally been used to enhance the length, thickness, and fullness of an individual's natural eyelashes. However, each cluster must be applied to the individual's eyelashes individually in order to avoid having the clusters of artificial lashes stick together and to ensure multiple clusters are evenly distributed across the width of the individual's lash line.\n\nAlternatively, false eyelashes may be applied directly to an individual's eyelid. False eyelashes come in strips (and thus may also be referred to as “strip lashes”) that can be trimmed to fit the width of the individual's eyelid. While a strip of false eyelashes can be applied in a single motion, false eyelashes are easily distinguishable from the individual's natural eyelashes and may be uncomfortable when worn for extended periods of time.",
