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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The method relates a method of coloring hair utilizing ultrasound waves to generate and apply to hair a spray containing a hair dye.[0003]2. Description of the Related Art[0004]Hair, at least the portion generally seen, is composed of dead cells forming the outer cuticle and inner cortex. The dead cells forming the cuticle are flat in structure, covering and protecting the cortex much like singles covering a roof. The dead cells forming the cortex are densely packed with keratin bundles and contain the pigment giving hair its color. The cells of the cuticle are devoid of pigment. Coloring hair, accordingly, requires replacing, lessening, supplementing and / or masking the pigment within the cortex with a new pigment to provide the desired color. This requires absorption of the new pigment by the hair to be colored.[0005]Providing a somewhat permanent coloring to hair that can survive repeated washing requires a chemical r...

AI Technical Summary

Benefits of technology

The patent text describes a method for coloring hair using ultrasound waves. The method involves using a spray containing a hair dye and a vibrating ultrasound horn to atomize the dye and deposit it into the hair. The ultrasound waves create small droplets of dye that can fill the spaces within the hair's cuticle, resulting in a more uniform and consistent color. The method also reduces the need for harmful oxidants and irritating alkaline agents. The hair is exposed to the near field of the ultrasound waves during atomization, which can change the dye's electron distribution and generate radicals, resulting in less damage to the hair and increased absorption of the dye. The method can be performed at home and is a safer alternative to traditional hair dye methods.

Problems solved by technology

The oxidants or alkaline agents generally utilized to achieve a consistent and somewhat permanent application of hair dye are often damaging to the hair.

They can also be unpleasant to work with due to, among other things, their tendency to irritate the skin.
