Novel systems and methods for performing treatment (e.g., coloration) of keratinous fibers are disclosed. The methods and systems utilize one or more of a dispensing device which is configured to provide customized composition for treating keratinous fibers (e.g., a coloring composition), optionally formed from tablets; an optical reader, for obtaining sufficient characteristics of the keratinous fibers to make a realistic prediction of the outcome of a treatment (e.g., coloring treatment); a computational units for predicting an outcome of a treatment, optionally being interfaced with the dispensing device and for selecting a customized treatment; and tablet formulations which are useful in preparing customized composition for treating keratinous fibers. Further disclosed are rapidly disintegrating tablets for use in the preparation of compositions for treating keratinous fibers.

An application device for applying hair-coloring composition, comprising a device body, comprising a first reservoir comprising a first piston; the first reservoir configured to receive a first part of a hair-coloring composition; a second reservoir comprising a second piston; the second reservoir configured to receive a second part of a hair-coloring composition; and a dispensing mechanism associated with the first piston and with the second piston; the dispensing mechanism configured to sealingly move the first piston inside the first reservoir and the second piston inside the second reservoir; and an application cap, comprising a mixing mechanism; and a plurality of projecting tines; wherein the application cap is configured for reversible-connection with the device body such that, when the application cap is connected with the device body, the first reservoir and the second reservoir are sealed from the outside except channels of the plurality of projecting tines which are in fluid communication with the first reservoir and the second reservoir, through the mixing mechanism; and wherein the dispensing mechanism is configured, when activated, to move the first piston and the second piston towards the plurality of projecting tines thereby mixing the first part of the hair-coloring composition with the second part of the hair-coloring composition to form a mixed hair-coloring composition to be dispensed through the plurality of projecting tines.

A cosmetic composition for dyeing keratinous fibers is provided herein. The cosmetic composition includes water and from about 6 to about 12 wt % organic solvent relative to the weight of the composition. The organic solvent includes from about 80 to about 100 wt % propylene carbonate and from about 0 to about 20 wt % benzyl alcohol. The cosmetic composition has a pH value in the range from about 1.0 to about 5.5 and at least one acid directly absorbed dye.

Formulation delivery systems, formulation delivery devices, and formulation cartridges for the same are provided. Formulation delivery systems include a reusable handle, a formulation dispensing assembly, and a controller. The formulation dispensing assembly includes a reciprocating nozzle assembly and a pump. The reciprocating nozzle assembly is fluidically-coupleable to the formulation cartridge or the cleaning cartridge received within the reusable handle. Formulation delivery devices include a reusable handle configured to receive a formulation cartridge therein, and a formulation dispensing assembly disposed in the reusable handle. The formulation dispensing assembly includes fluid conduits, a pump fluidically connected to the fluid conduits, a reciprocating nozzle assembly, and a controller. Formulation cartridges include a reusable cartridge body and a formulation cartridge refill unit.

A rotating cosmetics brush includes a movable brush head mounted in a housing. A motion actuator is operative to move the brush head in a rotational motion, wherein the brush head rotates about a rotational axis and simultaneously moves in a non-oscillatory movement about another axis different than the rotational axis.

The present technology provides a dry shampoo composition comprising clay, natural starches and a natural oil absorbent. Such dry shampoo compositions are highly absorbent, fine, light and resistant to clumping. In some embodiments, the dry shampoo compositions are useful as alternatives to conventional wet shampoo in methods for cleaning hair.

A composition dispensing device engages a body surface, such as the scalp, while simultaneously dispensing a composition from an attached container on the surface. The device detachably joins a container of a composition and enable uniform dispensing and application of the composition on a body surface. The device comprises a housing that detachably joins with a container of composition. A platform having a plurality of apertures rests coplanar with the housing. A plurality of conduits, or hollow bristles, extend from the platform. The conduits include channels that are in communication with the housing and the container of composition. The conduits are arranged as inner and outer conduits, with the outer conduits being slightly longer to create a generally concave effect. The conduits terminate at an angled tip portion that engages the body surface, while simultaneously dispensing the composition from terminal openings or lateral openings formed at the tip.

Described herein is a method for treating and coloring hair including un-pigmented hair. The method includes (a) providing a first composition including one or more heavy metal ion sequestrants; (b) applying the first composition to the hair; (c) providing a second composition including one or more weak acids having a pKa from 2.5 to 5; (d) applying the second composition to the hair; (e) providing a third composition including one or more direct dyes chosen from nitro dye, disperse dye, cationic dye, acid dye, basic dye, neutral azo dye and mixtures thereof, and (f) applying the third composition to the hair. The third composition is able to decrease the reflectance of un-pigmented hair in a wavelength range from 530 nm to 670 nm.
