A hair cosmetic material includes a first agent containing an alkali agent and a second agent containing an oxidizing agent. These first agent and second agent are used in a double structure container provided with a mechanism of separating the first agent and the second agent from each other and simultaneously discharging the both agents by a propellant. In the double structure container, a space for filling the first agent and a space for filing the second agent are each independently provided in the inside of a compressed gas filling space having a propellant for pressurization filled therein. Each of the first agent and the second agent is discharged in a liquid state, and each of the first agent and the second agent has a viscosity falling within the range of from 7,000 to 30,000 mPa.Math.s at 25 C.

The present invention relates to a double-structure aerosol container for a two-agent type hair cosmetic, having an outer vessel and an inner bag to be housed in the outer vessel. An inner bag includes an inner layer and an outer layer both of which are formed of a polyolefin resin and an intermediate layer formed of a cyclic olefin copolymer or an amorphous polyester resin, thereby preventing an inner surface of the outer vessel from corrosion after storing at high temperature with the inner bag filled with a second agent containing hydrogen peroxide as a major ingredient and at least one of an organic acid or an organic acid compound.

A hair coloring appliance includes a handle and a hair color delivery system supported within the handle. A nozzle assembly is adapted to receive hair color. The nozzle assembly includes a stationary frame and a nozzle array through which the hair color is delivered to the hair and a plurality of filaments adjacent the nozzles which are longer than the nozzles, acting as a stand-off between the nozzles and the scalp. A motor reciprocates the nozzle array back and forth as hair color moves through the nozzles.

Method for producing a shading on the hair, comprising the stage consisting in: subjecting an amount of a composition (100) capable of exhibiting a variation in its hair dyeing or bleaching power under the effect of a chemical and/or energy stimulus to the said stimulus, so as to obtain at least two fractions (1000; 2000) of the said amount each having a hair dyeing or bleaching power distinct from that of the other fraction, the composition (100) being subjected to the stimulus before or after it is brought into contact with the hair and the composition producing, after exposure to the said stimulus and being brought into contact with the hair, a shaded dyeing or bleaching.

A valve assembly in which contents respectively packed in multiple storage parts which cannot be reacted with each other in the middle of passage, an aerosol container equipped with the valve assembly, and an aerosol products are provided. An aerosol container comprises an outer container, two inner bags inserted into the outer container, and valve assembly which closes inner bags and outer container. The valve assembly comprises aerosol valves which are separated independently from each other and a holding member for holding the aerosol valves and for fixing the aerosol valves to the outer container.

Disclosed are a hair colouring device and method of its use. The device includes a top housing, a bottom housing movably engaged to the top housing at distal ends using an engagement mechanism that enables the device to alternate between a closed position and an open position, a first cartridge carrier for receiving a first colourant-filled cartridge, the first cartridge carrier being removably disposed within an opening provided on the top housing, a second cartridge carrier for receiving a second colourant-filled cartridge, the second cartridge carrier being removably disposed within an opening provided on the bottom housing, a pair of applicator tips, each of the applicator tips being disposed at a proximal end of the first cartridge carrier and the second cartridge carrier. The device allows accurate, non-messy and even application of the hair colouring composition to the selected one or more strands of hair more quickly and effectively.

Examples relating to twisted teeth combs are described herein. An example apparatus may include a base with one or more twisted teeth attached. Particularly, each twisted tooth may have a twisted structure, such as a structure similar to a twist drill bit used by a power drill. As such, the arrangement of the teeth on the apparatus can vary within examples. For instance, the apparatus can include straight teeth and twisted teeth arranged in an alternating order. Additionally, in some implementations, an example apparatus relating to twisted teeth combs can include one or more components, such as a handle connected to the base and/or a storage compartment configured to receive and hold liquids (e.g., hair gel) or substances.

A formulation delivery appliance can be used for treatment of the hair and scalp, such as an appliance used to color hair. The appliance may include a container having an aperture and being configured to retain a volume of formulation. The formulation delivery appliance may further include an elongate engagement element having a channel extending therethrough and being configured to be at least partially received by the aperture of the container when the container is mounted to the engagement element. A vent aperture is formed in the engagement element and provides fluid communication between the channel and an area outside of the engagement element when the container is disengaged from the engagement element. The vent aperture is sealed, and the channel receives a flow of formulation from the container when the container is mounted to the engagement element.

Hair coloring appliances include an elongate handle and a consumable assembly removably couplable to the handle. The consumable assembly has a manifold chamber with a fluid inlet in selective fluid communication with a first formulation fluid source, a plurality of outlet nozzles configured to discharge a first formulation from the manifold chamber, and a distribution protrusion extending into the manifold chamber and configured to direct the flow of the first formulation from the fluid inlet to each of the plurality of outlet nozzles.
