A hair treatment kit comprises a hair treatment composition selected from the group of semi-permanent oxidative and/or direct dye hair colorant compositions, hair bleaching compositions, highlighting compositions, and combinations thereof, a reservoir for holding the temporary hair treatment composition, and an applicator fluidly connected to the reservoir for selectively applying the hair treatment composition to a targeted area of hair. Methods of applying the hair treatment composition comprise selectively engaging the applicator with a targeted area of hair, leaving the hair treatment composition in the targeted area for a time period, washing the hair treatment composition out of the targeted area, closing the reservoir to preserve remaining hair treatment composition for later use, and reapplying the hair treatment composition to the targeted area.

Hair dye composition and method of dyeing hair that targets only at least one grey part using a permanent hair dye component comprising a specific volume percentage of a particulate pigment to permanent hair dye component. The purpose of some embodiments of the invention is to delay the need for women to dye their hair in full. At least one pigment particle (about 0.0770 ml or about 1/64th of a teaspoon) may be added to a bottle of 71 ml of permanent hair dye, which allows the permanent hair dye composition to become visible and allows for more accuracy during application. Using small quantities of 5 cc per application (hair dye: 2.5 ml; developer: 2.5 ml) reduces the amount of dye applied to needless areas of the hair. The use of a make-up sponge stick allows for better accuracy. The composition is multi-use, and provides for 28 applications (71 ml bottle of dye and 71 ml of developer), and will save users time and money. All these characteristics provide for a hair dye composition that significantly reduces the amount of harmful chemicals applied to users' hair.

A custom hair coloring container, components of the container, and method of use and doing business. In one embodiment, the container includes a container body, a hair colorant container section of the container body removably mountable to a peroxide container section of the container body, and the hair colorant container section and the peroxide container section collectively forming a cavity with an inside surface. The hair colorant container section may include a first interior seal threadedly engaged with the inside surface within the hair colorant container, and the peroxide container section may include second interior seal threadedly engaged with the inside surface within the peroxide container section.

Formula delivery devices include a handle and a consumable assembly. The handle has a handle shell, and the consumable assembly is configured to be removably joined with the handle by insertion into the handle shell. The consumable assembly has a formulation container disposed in an elongate housing and is configured to contain a volume of a formulation. The formulation container is provided with a sealing member configured to enable fluid communication with the formulation container.

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 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 device includes a pump and a brushhead. The pump includes a housing and plunger. The housing has an upper opening, a cavity configured to store a composition therein, and a tip having a dispensing opening. The plunger is slidably disposed within housing such that it is moveable with respect to the housing. The brushhead includes a first plurality of bristle bores and a second plurality of bristle bores, each of which extend from a bottom surface of the brushhead towards an opposing top surface and have a bristle bundle extending therefrom. The brushhead includes a generally central throughhole extending between the bottom surface and the opposing top surface. The pump is coupled to the brushhead via the tip of the housing such that actuation of the plunger causes a portion of the composition stored in the housing to be dispensed on at least a portion of the bristle bundles.

A hair coloring membrane assembly for enhancing the dye process of grey hair includes a dispenser that has an opening therein. A plurality of strips is positioned in the dispenser and is selectively removable from the dispenser. Thus, each of the strips may be positioned on a scalp during hair coloring. Each of the strips comprises a first layer, a second layer and a third layer. Each of the first layer and the third layer is comprised of a fluid absorbent material to transfer a fluid hair dye onto the scalp thereby enhancing the fluid hair dye to penetrate roots of hair being dyed. The second layer is comprised of a light reflective material and the second layer is infused with a fluid emulsifier. The fluid emulsifier is released into the hair thereby enhancing absorption of the fluid hair dye into the hair.

A hair color retouch kit, components of the kit, and methods of use and doing business. The kit can include one or more mixing containers. In one embodiment, a mixing container provides a colorant compartment for sealingly or separately containing a custom hair coloring formulation and peroxide compartment for sealingly or separately containing peroxide. The mixing container(s) can be used by a professional hair colorist to provide a hair coloring client with custom hair coloring formulation and peroxide that can be mixed and applied by or for the client to hair regrowth that occurs after a hair coloring session with the professional. The kit can provide other components as desired, such as a mixing spatula, an applicator brush, and instructions for example. The kit can be packaged in attractive and efficient packaging, include indicia identifying the source of the kit, and be customized to promote the colorist, salon, or other entity.

A cosmetic product for changing the color of keratin fibers, in particular human hair, includes a coloring preparation (F) that is packaged in a reclosable container (C), wherein the coloring preparation (F) includes, in a cosmetic carrier, (a) at least one first preservative from the group of sodium sulfite, potassium sulfite, potassium hydrogen sulfite, sodium hydrogen sulfite, zinc pyrithione, benzoic acid, salicylic acid, sorbic acid, formic acid, propionic acid and the physiologically acceptable salts of the aforementioned acids, and (b) at least one second preservative from the group of 2-phenoxyethanol, benzyl alcohol, 1-phenoxypropan-2-ol, isopropanol and ethanol, and (c) at least one oxidation dye precursor and/or one substantive dye. A method for changing the color of the hair at the roots of the hair involves the use of such a product.
