Abstract: An array of hair dye products formulated to provide the same hair color to users with different hair colors or a different variety of colors of users with the same hair color. The array includes at least two hair dye products. The hair dye products each include a hair dye composition contained in a package. A first hair dye product in the array includes a photochromic dye that provides a color change to a first hair color, and a second hair dye product in the array includes the same photochromic dye that provides the same color change to a second, different color of hair. The array may also include two or more hair dye products that contain different ratios of photochromic dye(s) to provide users with different hair colors the same or different tunable hair colors.

Abstract: A tunable hair dye composition that includes a photochromic dye, a cosmetically acceptable solvent and, optionally, a carrier. When activated with a suitable activating electromagnetic radiation, the photochromic dye molecule changes color, thereby imparting a temporary color change to the composition and hair to which it is applied. When deactivated, the photochromic dye is generally colorless. The color imparted by the photochromic dye can be tuned by adjusting the wavelength and/or fluence of the activating and/or deactivating electromagnetic radiation. Thus, a wide variety of different hair colors can be obtained from a single hair dye composition containing specific combinations of photochromic dyes.

Abstract: Virtually immersive and physical digital systems and methods are described for dispensing physical consumer products. In various aspects, such systems and methods comprise receiving, by one or more processors from an input controller of a pedestal, a first selection corresponding to a selected virtual product selected from one or more virtual rendered products as rendered on a virtually immersive GUI. Based on the first selection, first virtual immersive graphical content, comprising image frame(s) depicting the selected virtual product, is rendered on a display screen. A second selection corresponding to the selected virtual product is received from the input controller causing second virtual immersive graphical content to be rendered the display screen. The second virtual immersive graphical content comprises image frame(s) depicting the selected virtual product being virtually dispensed or provided.

Abstract: Disclosed is a method of preparing an encapsulated liquid composition comprising the steps: preparing a frozen shaped unit of a liquid composition; and forming a shell to encapsulate the frozen shaped unit. The shell is formed by, for example, an alginate gel. The method of the present invention is suitable to provide, for example, bigger capsules and/or shaped capsules even for liquid compositions with low viscosity.

Abstract: Disclosed is an encapsulated liquid composition comprising a shell and the liquid composition contained inside of the shell, wherein the encapsulated liquid composition meets at least one of the conditions: the encapsulated liquid composition has other shapes than spherical shape; the encapsulated liquid composition contains 2 liquid compositions having different colors inside of the shell, and the 2 compositions form stripe, marble, and/or rainbow; and/or the encapsulated liquid composition contains smaller inner capsule, where in the smaller inner capsule is also an encapsulated liquid composition comprising a shell and the liquid composition contained inside of the shell, wherein the shell is formed by a material selected from the group consisting of alginate gel, carrageenan gel, chitosan gel, or mixtures thereof.
