Enhanced Hair Color Alteration Systems and Methods
Legal Citation
Summary of the Inventive Concept
This invention relates to improved systems, methods, and kits for altering the color of hair, enhancing vibrancy, and providing additional benefits such as hair protection and UV protection.
Background and Problem Solved
The original patent disclosed systems, methods, and kits for altering the color of hair using a pre-treatment composition and a dyeing composition. However, the existing invention has limitations in terms of color vibrancy, hair damage, and lack of additional benefits. The present inventive concept addresses these limitations by introducing pH-dependent amine-based compounds, combinations of non-surface active amine-based compounds, and additives that enhance hair color vibrancy, protect hair, and provide UV protection.
Detailed Description of the Inventive Concept
The new inventive concept comprises a system for altering the color of hair, including a pre-treatment composition with a pH-dependent amine-based compound that selectively releases active molecules at a specific pH, and a dyeing composition with a microtube-dye composite and an optional pH-adjusting agent. The pre-treatment composition can also include a combination of non-surface active amine-based compounds having different molecular weights, an antioxidant, and/or a hair-protecting agent. The dyeing composition can further comprise a color-enhancing additive, a UV-protecting agent, and/or a moisturizing additive. The system can be applied using a temperature-controlled applicator, and the pre-treatment composition can include a thermal-activated compound.
Novelty and Inventive Step
The new claims introduce the concept of pH-dependent amine-based compounds, combinations of non-surface active amine-based compounds, and additives that enhance hair color vibrancy, protect hair, and provide UV protection, which are not disclosed in the original patent. These innovations provide a non-obvious solution to the limitations of the existing invention.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept can include variations in the pH-dependent amine-based compounds, the combinations of non-surface active amine-based compounds, and the additives used. Additionally, the system can be adapted for use with different types of hair, such as virgin, colored, or damaged hair.
Potential Commercial Applications and Market
The enhanced hair color alteration systems and methods have significant commercial potential in the beauty and cosmetics industry, particularly in the hair care segment. The target market includes professional hairstylists, salons, and individual consumers seeking high-quality hair color alteration products and services.

Section 103 Obviousness Analysis (PHOSITA)
Field of Art
Cosmetic chemistry and hair treatment technologies, specifically focused on hair coloration methods involving chemical compositions, surface treatments, and color alteration systems
Person of Ordinary Skill (PHOSITA) Profile
A professional with advanced degree in chemistry or chemical engineering, specialized knowledge of hair treatment formulations, understanding of polymer chemistry, surfactant interactions, and color modification techniques for keratinous substrates
Obviousness Rationale
A person having ordinary skill would recognize that the PTD's variations represent predictable extensions of the source patent's core hair coloration methodology by introducing incremental improvements in composition chemistry, pH manipulation, and functional additive strategies that are consistent with known hair treatment design principles.
