Enhanced Hair Color Toning Compositions and Methods

The present inventive concept relates to improved hair color toning compositions and methods that enhance the color depositing ability, provide a synergistic effect, and improve hair's texture and manageability.

The original patent disclosed compositions and methods for imparting color and/or tone to the hair. However, these compositions had limitations in terms of color depositing ability, hair texture, and manageability. The present inventive concept addresses these limitations by introducing new compositions and methods that provide enhanced color depositing ability, a synergistic effect, and improved hair texture and manageability.

The enhanced hair color toning compositions comprise at least one amino acid, at least one carboxylic acid, monoethanolamine, and at least one hair coloring agent. The at least one amino acid is present in a concentration of at least 5% by weight, relative to the total weight of the composition, to enhance the color depositing ability of the composition. Alternatively, the at least one amino acid can be selected from a combination of taurine and glycine to provide a synergistic effect in enhancing the color depositing ability of the composition. Additionally, the composition can further comprise a conditioning agent to improve the hair's texture and manageability. The method for imparting color and/or tone to the hair involves applying the composition to the hair and then treating the hair with a heat styling tool to enhance the color depositing ability of the composition.

The new inventive concept is novel and non-obvious in that it introduces a higher concentration of amino acids, a synergistic effect of combining amino acids, and the addition of conditioning agents to improve hair texture and manageability. These features enhance the color depositing ability, provide a synergistic effect, and improve hair's texture and manageability, which are not disclosed in the original patent.

Alternative embodiments of the inventive concept include varying the concentration of amino acids, using different combinations of amino acids, and incorporating additional conditioning agents to improve hair texture and manageability. Variations of the method include using different heat styling tools, applying the composition in different ways, and using different hair coloring agents.

The enhanced hair color toning compositions and methods have significant commercial potential in the hair care industry, particularly in the professional salon market and the at-home hair coloring market. The inventive concept addresses the growing demand for hair coloring products that provide enhanced color depositing ability, improved hair texture, and manageability.
