Ultrasound Hair Dyeing Method

Abstract

A method of coloring hair utilizing ultrasound waves to generate and apply to hair a spray containing a hair dye is disclosed. Depending on the components of the dye, the effect of the ultrasound upon the components of the dye may reduce the oxidants and/or alkaline agents required to achieve the desired coloring of hair. Utilizing the ultrasound waves the dye is applied to hair and deposited within the spaces of hair's cuticle. Cavitations induced within the dye within the spaces of the cuticle then force the dye into the hair's cortex.

I claim: 
     
         1 . A method of dyeing hair comprising:
 a. generating a spray containing a coloring agent by delivering the coloring agent to a surface of an ultrasound horn emitting ultrasound waves;   b. depositing the coloring agent in spaces within the cuticle of the strand of hair by utilizing the ultrasound waves to apply the spray containing the coloring agent to the hair; and   c. forcing the coloring agent within the spaces within the cuticle into the cortex of the strand of hair by generating cavitations within the applied coloring agent.   
     
     
         2 . The method of  claim 1  wherein, the surface of the horn emitting ultrasound waves emits longitudinal waves. 
     
     
         3 . The method of  claim 1  further comprising, placing the hair within the far field of the ultrasound waves. 
     
     
         4 . The method of  claim 1  further comprising, exposing the applied coloring agent to the near field of the ultrasound waves. 
     
     
         5 . The method of  claim 4  wherein, exposing the applied coloring agent to the near field changes the number of electrons of the coloring agent. 
     
     
         6 . The method of  claim 4  wherein, exposing the applied coloring agent to the near field generates radicals of the coloring agent. 
     
     
         7 . The method of  claim 1  further comprising, placing the hair within the near field of the ultrasound waves while applying the spray containing the coloring agent to the hair. 
     
     
         8 . The method of  claim 1  further comprising, exposing the hair to focused ultrasound waves. 
     
     
         9 . The method of  claim 1  wherein, the cavitations within the applied coloring agent are generated by exposing the applied coloring agent to focused ultrasound waves. 
     
     
         10 . The method of  claim 1  wherein, the longitudinal waves have a frequency between approximately 15 kHz and 40 MHz. 
     
     
         11 . The method of  claim 1  further comprising generating a spray containing a base by delivering the base to a surface of an ultrasound horn emitting ultrasound waves and depositing the base in spaces within the cuticle of a strand of hair by utilizing the ultrasound waves to apply the spray containing the base to the hair. 
     
     
         12 . The method of  claim 11  further comprising, forcing the base within the spaces within the cuticle into the cortex of the strand of hair by generating cavitations within the applied base and coloring agent. 
     
     
         13 . The method of  claim 11  wherein, the coloring agent is a coupler. 
     
     
         14 . The method of  claim 11  further comprising, exposing the applied base to the near field of the ultrasound waves. 
     
     
         15 . The method of  claim 14  wherein, exposing the applied base to the near field changes the number of electrons of the base. 
     
     
         16 . The method of  claim 14  wherein, exposing the applied base to the near field generates radicals of the radicals. 
     
     
         17 . The method of  claim 11  further comprising, placing the hair within the near field of the ultrasound waves while applying the spray containing the base to the hair. 
     
     
         18 . The method of  claim 12  wherein, the cavitations within the applied base are generated by exposing the applied base to focused ultrasound waves. 
     
     
         19 . The method of  claim 1  further comprising, applying an alkaline agent to the strand of hair. 
     
     
         20 . The method of  claim 1  further comprising, applying an oxidant to the strand of hair.
