SYSTEMS, METHODS AND KITS FOR MODIFYING HAIR COLOR

The present disclosure relates to systems, methods and kits for modifying hair color.

Background

Consumers wish to use cosmetic compositions to improve the appearance of keratin substrates such as the hair, for example, by modifying the color, the style and/or the shape of the hair, and/or by imparting various properties to the hair, such as shine and conditioning. Many of the compositions and processes known to improve the appearance of hair involve chemical treatment of hair. For example, the process of changing hair color may involve coloring the hair by depositing an artificial color on the hair which provides a different shade or color to the hair.

Classic hair coloring processes include permanent and semi-permanent or temporary hair coloring. Permanent hair color compositions use oxidation color precursors, which are also known as primary intermediates or coupling agents. These oxidative color precursors are colorless or weakly colored compounds which, when combined with oxidizing products, give rise to colored complexes by a process of oxidative condensation. Permanent hair color compositions also contain ammonia or other alkalizing agents, which cause the hair shaft to swell, allowing small oxidative dye molecules to enter the cuticle and cortex before the condensation process by oxidation is complete. The larger color complexes resulting from the oxidative reaction are then trapped inside the hair fiber, thus permanently modifying the color of the hair. On the other hand, semi-permanent or temporary hair coloring compositions usually use pigments, fat-soluble dyes, natural dyes or direct dyes chosen from acidic (anionic), basic (cationic) or neutral direct dyes which are deposited on the hair fiber to bring color to the hair.

It is known that conventional hair coloring compositions, however, have drawbacks. For example, oxidative hair coloring processes usually damage the hair, making it for example brittle, dry, rough and/or brittle, and/or irritate the scalp or skin due to the use of peroxide. hydrogen and alkaline agents necessary to achieve permanent coloring of hair fibers.

Semi-permanent or temporary hair coloring compositions can impart chromatic color to hair, but the color may lack persistence due to the nature of the interactions that bind the direct dyes to the hair fiber and/or sensitivity to light . Additionally, semi-permanent or temporary hair coloring compositions can also cause skin and/or scalp irritation. Furthermore, semi-permanent or temporary hair dyes are usually not able to provide the same vitality or diversity of shades as permanent hair dye compositions.

It has previously been found that aluminosilicate microtubes can be used as a carrier for synthetic or natural dyes, for example as described in U.S. Patent No. 10,799,439. However, although this microtube-dye composite can be used to color the hair in a manner that does not damage the hair or irritate the skin and/or the scalp, the method can lead to unsatisfactory color deposition and hair coloring effectiveness. Also, hair color may not persist after multiple shampoos.

The present inventors have now surprisingly discovered hair coloring methods using a microtube-dye composite that provides improved color deposition and more vibrant hair colors, while retaining the benefits of less hair damage and/or less hair loss. skin and/or scalp irritation.
