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 section that detachably joins with a container of composition. A platform section having a plurality of apertures rests coplanar with the housing section. A keying mechanism secures the platform section to the housing section. A plurality of conduits, or hollow bristles, extend from the platform section. The conduits include channels that are in communication with the housing section 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.

A smart device having a hair color application (App) stored thereon capable of providing and receiving hair color information to and from a user. A photograph of the user's hair is taken using the smart device. A palette of possible colors is then calculated in view of the photograph and other hair information provided by the user. The smart device includes a display for showing the calculated colors, and for showing colors selected by the user on the user's hair.

A smart applicator for liquid cosmetic to hair, skin or nails is described, comprising a position indicator to measure the relative change of position of the applicator across a nearly flat surface; a sensor array to measure the prior color or cosmetic condition of hair strands or skin condition; an optional comb array to direct hair strands from their roots into a regular linear array; a microcontroller which outputs electrical signals to operate an array of micro-mechanical or inkjet nozzles aligned with the comb array so as to dispense dye or cosmetic droplets to the hair strands or skin surface according to input received from said sensors.

An integrated at least two component mixing and delivery system and method for creating a new mixture from a first component contained within a first enclosure and a second component contained within a second enclosure that is contained within the first enclosure and, via a series of operations that mix the two components and enable the application of through an applicator tip the placement of the new mixture on at least one surface or a portion thereof.

A device for selectively entraining hair strands from the scalp has at least one hooking or a clamping applicator, the at least one hooking applicator employing a hook that rotates to entrain the hair strands, and the clamping application employing a flat plate. A hair product container having a styling product or hair color therein is provided. The device also includes a mechanism to apply the hair product to the entrained hair stands. The mechanism using a hooking applicator can include a worm gear.

The application provides a hair coloring brush. The hair coloring brush can include a handle and a detachable brush cap that detachably couples to the handle. The handle can include an elongated body, a brush attachment protrusion, where the brush attachment protrusion extends outward from the elongated body and has a first protrusion side and a second protrusion side. The handle can also include a first side ridge and a second side ridge. The detachable brush cap can include a distal brush end, a plurality of bristles, and a cavity opposite the distal brush end, where the cavity has a cavity wall and an internal groove located in the cavity wall. The first side ridge and the second side ridge can tension fit in the internal groove when the detachable brush cap is inserted over the brush attachment protrusion.

Personal care devices (or apparatuses) are described to deliver/activate a bioactive compound/botanical compound/biologically active molecule (including a regulatory protein/growth factor) or a mixture of bioactive compounds/botanical compounds/biologically active molecules (including regulatory proteins/growth factors) for growth and protection of hair or rejuvenation and protection of skin, which utilizes nanoencapsulation/nanoemulsion and/or activation/photoactivation. Such devices (or apparatuses) utilize a light low intensity module/x-ray and nanooptical elements/three-dimensionally (3-D) printed micro/nanostructures.

A drive shaft coupling is provided, such as a coupling used with a formula delivery appliance. The drive shaft coupling generally includes a drive gear and a driven gear, with one of the drive gear and driven gear having a biasing member to allow axial translation. The drive shaft coupling is generally configured to transfer rotation from the drive gear to the driven gear. In one aspect, the drive shaft coupling is capable of alignment and coupling of the drive gear and driven gear upon the radial sliding of the coupling from a non-engagement position to an engagement position.

A hand sponge for styling facial hair includes a glove body having a main portion and five finger portions, a backside of the glove having a substantially bottom surface made of sponge which has rough thickness, and the sponge of the backside of the glove including a plurality of spaced-apart holes and a plurality of bumps.

A modular and multi-chamber hair dye dispenser and kit including the same are provided. Namely, the dispenser comprises a first and second chamber configured to each hold a fluid substance and threadedly engage one another. A pressure activated gate is disposed between the chambers and configured to selectively permit fluids held therein to mix upon screwing the chambers into one another. A removable spacer may be disposed between the chambers to prevent breach of the gate until desired. An outlet secured within an open front end of the first chamber is configured to dispense mixed fluid via one or more openings and, as desired, receive an interchangeable applicator. In a kit, fluid substances may comprise hair coloring agent and a developer, activator, or oxidizer.
