Method for lash lengthening

Abstract

A method for lengthening lashes is provided, along with a kit for accomplishing the method. The method comprises (i) applying a glue onto an eyelash, (ii) allowing the glue to dry for a period of time; and then (iii) depositing a separate individual fiber onto a distal portion of the eyelash using a microbristle brush applicator having a bristle density above 4 bristles/mm2, where each fiber has a diameter greater than 30 microns and a length of 4 mm or less and each fiber is held electrostatically by the microbristle brush applicator. Mascara can then be applied to some or all of the lash and attached fiber.

What is claimed is: 
     
         1 . A method for lengthening lashes, comprising:
 applying a water- or oil-based glue onto a distal portion of an eyelash using a first applicator;   allowing the water- or oil-based glue to dry for a period of time; and   depositing a separate individual fiber onto the distal portion of the eyelash using a second applicator, the second applicator being a microbristle brush applicator having a bristle density above 4 bristles/mm 2 , the separate individual fiber being held electrostatically by the microbristle brush applicator, and the separate individual fiber has a diameter greater than 30 microns.   
     
     
         2 . The method according to  claim 1 , wherein the separate individual has a length of 4 mm or less. 
     
     
         3 . The method according to  claim 1 , further comprising applying a mascara over the deposited separate individual fiber. 
     
     
         4 . The method according to  claim 1 , wherein the water- or oil-based glue comprises a plurality of solvents in a total amount of between 40% and 60% by weight of the composition. 
     
     
         5 . The method according to  claim 4 , wherein the water- or oil-based glue further comprises a plurality of copolymers, the plurality of copolymers being present in a total amount of between 40% and 50% by weight of the composition, each of the plurality of copolymers comprising: (i) a monomer of acrylic acid, methacrylic acid, or one of their simple esters, (ii) a hydrogenated styrene monomer; or (iii) a combination thereof 
     
     
         6 . The method according to  claim 5 , wherein the water- or oil-based glue further comprises less than 1% by weight of a thickening agent. 
     
     
         7 . The method according to  claim 1 , wherein the separate individual fiber comprises a synthetic fiber. 
     
     
         8 . The method according to  claim 7 , wherein the synthetic fiber comprises rayon or a nylon. 
     
     
         9 . The method according to  claim 1 , wherein the period of time is less than 10 seconds. 
     
     
         10 . The method according to  claim 1 , wherein a bristle diameter of each bristle of the microbristle brush is between 0.15 mm and 0.35 mm. 
     
     
         11 . The method according to  claim 1 , wherein a length of each bristle of the microbristle brush is between 1 mm and 3 mm. 
     
     
         12 . The kit, comprising:
 a first composition comprising a water- or oil-based glue;   a first applicator configured to apply the first composition to an eyelash;   a plurality of separate individual fibers, each having a diameter greater than 30 microns and a length of 4 mm or less;   a second applicator configured to deposit the separate individual fiber onto the eyelash electrostatically, the second applicator being a microbristle brush applicator having a bristle density above 4 bristles/mm 2 ; and   optional instructions for use.   
     
     
         13 . The kit according to  claim 12 , wherein the first applicator is formed as part of a cap on a first container, the first container containing the first composition. 
     
     
         14 . The kit according to  claim 12 , wherein the second applicator is formed as part of a cap on a second container, the second container containing the plurality of separate fibers. 
     
     
         15 . The kit according to  claim 12 , further comprising:
 a second composition comprising a mascara; and   a third applicator configured to apply the second composition over the separate individual fiber after the separate individual fiber has been deposited onto an eyelash.   
     
     
         16 . The kit according to  claim 15 , wherein the third applicator is formed as part of a cap on a third container, the third container containing the second composition. 
     
     
         17 . The kit according to  claim 12 , wherein a bristle diameter of each bristle is between 0.15 mm and 0.35 mm and a length of each bristle is between 1 mm and 3 mm.
