Curing led uv

Abstract

An attachment device for a hair dryer that includes an ultraviolet (UV) light for facilitating curing of a cosmetic composition, such as a hair dye, that is applied to hair of an individual, as well as a hair dryer system that includes such an attachment device. Methods of using the attachment device and/or a system for curing a cosmetic composition, and computational devices configured to perform all or part of the methods.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 
     
         1 . An attachment device for a hair dryer, the attachment device comprising an ultraviolet (UV) light configured to cure a cosmetic composition. 
     
     
         2 . The attachment device of  claim 1 , wherein the attachment device is an after-market device configured for use with a hair dryer and comprises a plurality of securements for securement of the attachment device to the hair dryer. 
     
     
         3 . The attachment device of  claim 2 , wherein the plurality of securements is configured for securement of the attachment device to a securement rail of the hair dryer. 
     
     
         4 . The attachment device of  claim 1 , wherein the cosmetic composition is configured for application to hair of an individual and is UV photocurable. 
     
     
         5 . The attachment device of  claim 4 , wherein the cosmetic composition includes a hair dye that is curable with hot air of the hair dryer, UV light of the attachment device, or both. 
     
     
         6 . A hair dryer comprising a securement rail configured for securement of the attachment device of  claim 1  thereto. 
     
     
         7 . A hair dryer system comprising the hair dryer of  claim 6 . 
     
     
         8 . A method for curing a cosmetic composition, the method comprising:
 applying the cosmetic composition to a surface;   activating a blower of a hair dryer, such that the hair dryer blows air onto the cosmetic composition on the surface; and   activating a UV light of an attachment device for the hair dryer, such that UV light emitted from the attachment device irradiates the cosmetic composition on the surface;   wherein the attachment device is attachable to the hair dryer.   
     
     
         9 . The method of  claim 8 , wherein the attachment device is attached to the hair dryer. 
     
     
         10 . The method of  claim 8 , wherein a beam of the UV light of the attachment device and a portion of the hot air blown by the hair dryer are coincident with a portion of the cosmetic composition on the surface. 
     
     
         11 . The method of  claim 8 , wherein the cosmetic composition is formulated for application to hair of an individual and is UV photocurable. 
     
     
         12 . The method of  claim 11 , wherein the cosmetic composition includes a hair dye that is curable with hot air of the hair dryer, UV light of the attachment device, or both. 
     
     
         13 . A hair dryer system comprising computational circuitry configured to perform all or any portion of the method of  claim 8 . 
     
     
         14 . The hair dryer system of  claim 13 , wherein the computational circuitry comprises a processor and a non-transitory computer-readable storage medium having stored thereon instructions configured for execution by the processor. 
     
     
         15 . The hair dryer system of  claim 13 , wherein the computational circuitry comprises dedicated hardware circuitry.
