The plurality of hairs may be coupled together at a coupling region via an adhesive composition, heat fusion, or may be integrally formed. The coupling region is positioned at a distance from the proximate end such that the artificial hairs at the proximate end are not coupled or bound to each other. In this configuration, when the eyelash fan is applied to a single natural lash, the artificial hairs at the proximate end can wrap around the natural lash—thereby increasing the surface area and improving the wear time of the eyelash fan. ## Claims ### Claim 1 An eyelash fan system comprising: an eyelash fan comprising: a plurality of artificial hairs having a proximate end and a distal end, the plurality of artificial hairs widening from the proximate end towards the distal end; and a first adhesive composition binding the plurality of artificial hairs at a distance from the proximate end; a second adhesive composition applied to a natural eyelash of a wearer, wherein: the second adhesive composition is applied to at least a portion of each artificial hairs of the plurality of artificial hairs at the proximate end; and the at least a portion of each artificial hair wrapping at least partially around the natural eyelash and coupling to the natural eyelash via the second adhesive composition. ### Claim 2 (depends on 1) The eyelash fan system of claim 1, wherein: the eyelash fan is a first eyelash fan of a set of eyelash fans; and each eyelash fan of the set of eyelash fans is attached to a respective natural lash of the wearer's upper eyelashes. ### Claim 3 (depends on 1) The eyelash fan system of claim 1, wherein: the plurality of artificial hairs includes 3 to 10 artificial hairs; and the distance between the proximate end of the plurality of artificial hairs and the first adhesive composition is between 1 mm and 6 mm. ### Claim 4 (depends on 1) The eyelash fan system of claim 1, wherein the eyelash fan is configured to be applied over the natural eyelash. ### Claim 5 (depends on 1) The eyelash fan system of claim 1, wherein each artificial hair of the plurality of artificial hairs define a respective curvature with respect to the proximate end. ### Claim 6 (depends on 1) The eyelash fan system of claim 1, wherein: the first adhesive composition is positioned along a coupled region of the eyelash fan; and the plurality of artificial hairs along a cross section of the coupled region are aligned in a single row. ### Claim 7 An eyelash fan configured to be applied to a single natural lash of a wearer's natural eyelashes, the eyelash fan comprising: a plurality of artificial hairs having a proximate end of the eyelash fan and a distal end of the eyelash fan, the plurality of artificial hairs defining a fanned region; a coupling region positioned between the fanned region and the proximate end, the coupling region binding the plurality of artificial hairs together at a distance from the proximate end; and a base region extending from the coupling region to the proximate end, each artificial hair of the plurality of artificial hairs at the base region are unbonded with respect to each other artificial hair, the plurality of artificial hairs at the base region are configured to at least partially wrap around the single natural lash. ### Claim 8 (depends on 7) The eyelash fan of claim 7, wherein: the eyelash fan is a first eyelash fan of a set of eyelash fans; each eyelash fan of the set of eyelash fans is attached to a different natural lash of the wearer's natural eyelashes; and two or more eyelash fans of the set of eyelash fans have a different length. ### Claim 9 (depends on 7) The eyelash fan of claim 7, wherein: the plurality of artificial hairs includes 3 to 10 artificial hairs; the distance of the base region is between 1 mm and 6 mm; the coupling region comprises an adhesive composition extending longitudinally along the coupling region at a bonding length ranging between 1 and 5 mm; and a portion of the plurality of artificial hairs at the base region are substantially free of adhesive. ### Claim 10 (depends on 7) The eyelash fan of claim 7, wherein: each artificial hair of the plurality of artificial hairs is between 0.03 mm and 0.07 mm in diameter; and each artificial hair of the plurality of artificial hairs is formed from polybutylene terephthalate. ### Claim 11 (depends on 7) The eyelash fan of claim 7, wherein the plurality of artificial hairs does not exceed 36 artificial hairs. ### Claim 12 (depends on 7) The eyelash fan of claim 7, wherein the eyelash fan is a monolithic eyelash fan formed via a three-dimensional printing process. ### Claim 13 (depends on 7) The eyelash fan of claim 7, wherein the plurality of artificial hairs are bonded at the coupling region via heat fusion. ### Claim 14 An eyelash fan system comprising: an eyelash fan comprising: a plurality of artificial hairs having a proximate end and a distal end, the plurality of artificial hairs widening from the proximate end towards the distal end; and a first adhesive composition binding the plurality of artificial hairs at a distance from the proximate end; a second adhesive composition applied to a natural eyelash of a wearer, wherein: the second adhesive composition is applied to at least a portion of each artificial hairs of the plurality of artificial hairs at or near the proximate end; and the at least a portion of each artificial hairs wraps circumferentially at least partially around the natural eyelash and couple to the natural eyelash via the second adhesive composition. ### Claim 15 (depends on 14) The eyelash fan system of claim 14, wherein the eyelash fan is configured to be positioned on one natural eyelash. ### Claim 16 (depends on 14) The eyelash fan system of claim 14, wherein the first adhesive composition is cured prior to the eyelash fan being applied to the natural eyelash of the wearer. ### Claim 17 (depends on 14) The eyelash fan system of claim 14, wherein the distance of the first adhesive composition from the proximate end is between 1 mm and 6 mm. ### Claim 18 (depends on 14) The eyelash fan system of claim 14, wherein the second adhesive composition is an eye-safe adhesive applied in liquid form. ### Claim 19 (depends on 14) The eyelash fan system of claim 14, wherein the eyelash fan is configured to be applied under the natural eyelash. ### Claim 20 (depends on 14) The eyelash fan system of claim 14, wherein each artificial hair of the plurality of artificial hairs defines a curvature.
