Nail treatment method

Abstract

A nail treatment method includes: a base step of forming a base layer (40) on a nail plate (3); a coloring step of forming a color layer (50) on the base layer (40); and a top step of forming a top coat layer (60) on the color layer (50). In the base step, the base layer (40) is formed so as to be spaced apart from the base of the nail plate (3), and furthermore is formed in a shape including a raised part that has a highest portion at a position that is closer to the base of the nail plate than a position one-half of the length of the nail plate (3) is.

         7 . The nail treatment method according to  claim 1 ,
 wherein the top coat layer and the color layer that were previously formed are removed while maintaining the base layer previously formed on the nail plate, and   wherein, on the maintained base layer and the nail plate, the base step, the coloring step and the top step are performed so as to form a new base layer, a new color layer and a new top coat layer.   
     
     
         8 . The nail treatment method according to  claim 2 ,
 wherein, in the base step, the base gel is applied so as to have a teardrop or a drop shape tapered toward a tip of the nail plate in plan view in a second application or thereafter.   
     
     
         9 . The nail treatment method according to  claim 2 ,
 wherein, in the top step, application and curing of the top gel are performed several times, and the top coat layer is formed so as to have a raised part whose highest portion is located at a position one-fourth to one-half of the length of the nail plate from the base of the nail plate.   
     
     
         10 . The nail treatment method according to  claim 3 ,
 wherein, in the top step, application and curing of the top gel are performed several times, and the top coat layer is formed so as to have a raised part whose highest portion is located at a position one-fourth to one-half of the length of the nail plate from the base of the nail plate.   
     
     
         11 . The nail treatment method according to  claim 8 ,
 wherein, in the top step, application and curing of the top gel are performed several times, and the top coat layer is formed so as to have a raised part whose highest portion is located at a position one-fourth to one-half of the length of the nail plate from the base of the nail plate.   
     
     
         12 . The nail treatment method according to  claim 2 ,
