Described herein is a hair-loss prevention kit comprising a hair-loss composition comprising caffeine; and a brush comprising a body having a first major surface opposite a second major surface and a plurality of bristles extending from the second major surface of the body.

The present invention concerns a method of bundling a plurality of monofilaments into a bundle of monofilaments by means of a laser, a paint brush head including such bundle of monofilaments and a paint brush including such paint brush head.

A mold insert has at least one filament cavity and a stack of at least a first and second insert plates, wherein the first plate has a front face that closely abuts a front face of the second insert plate. A portion of the a filament cavity is provided in at least one of the front faces of the first and second insert plates such that the filament cavity is open at a top surface of the mold insert but does not extend to a bottom surface of the mold insert. A venting cavity is provided in the same front face of the insert plate in which the portion of the at least one filament cavity is provided. The venting cavity, which is in air-conducting connection with the blind-hole end of the filament cavity, has a depth between 1 μm and 20 μm. A method of manufacturing the mold insert includes providing first and second insert plates, forming a portion of a filament cavity into at least one of the front faces of the insert plates, forming a venting cavity into the front face with the filament cavity, and bringing the front faces of the plates into close abutment to form a filament cavity.

A device (2) is provided for applying a composition (P) to the eyelashes and/or the eyebrows. The device includes a molded applicator member (8) including a core (10) having a longitudinal axis (X) and rows of teeth that are carried by the core (10), preferably at least five rows, two teeth belonging to two consecutive rows not being parallel. The outside surface of at least one segment of the core (10) includes only one toothless portion, or only two toothless portions that are situated substantially opposite each other, or each toothless portion being of angular extent lying in the range 75° to 110° around the longitudinal axis.

A mold insert and an injection-molding machine including the mold insert. The mold insert has at least one filament cavity and a stack of at least a first and second insert plates, wherein the first plate has a front face that closely abuts a front face of the second insert plate. A portion of the a filament cavity is provided in at least one of the front faces of the first and second insert plates such that the filament cavity is open at a top surface of the mold insert but does not extend to a bottom surface of the mold insert. A venting cavity is provided in the same front face of the insert plate in which the portion of the at least one filament cavity is provided.

A toothbrush comprised at least one unitary brush head having a base and at least one filament and extending therefrom and having a free end terminating with a tip, wherein the filament has a length of from 6.0 mm to 20.0 mm between the base and the free end, and wherein the unitary brush head is made from a plastic material that has a melt flow rate of not greater than about 30 g/10 min measured in accordance with ISO 1133.

Provided is a polyester-based monofilament for a toothbrush, the monofilament having exceptional flexibility (usage feel), durability (bristle breaking resistance), and restoration properties (bristle opening resistance). The present invention relates to: a polyester-based monofilament for a toothbrush, the monofilament being characterized in that polytrimethylene terephthalate (PTT) and polybutylene terephthalate (PBT) are mixed at a proportion ranging from 85/15 to 65/35 in terms of weight ratio, and the shrinkage in boiling water is less than 1.0%; and a toothbrush in which the aforementioned polyester-based monofilament for a toothbrush is used in an erected bristle section.

A mold insert has at least one filament cavity and a stack of at least a first and second insert plates, wherein the first plate has a front face that closely abuts a front face of the second insert plate. A portion of the a filament cavity is provided in at least one of the front faces of the first and second insert plates such that the filament cavity is open at a top surface of the mold insert but does not extend to a bottom surface of the mold insert. A venting cavity is provided in the same front face of the insert plate in which the portion of the at least one filament cavity is provided. The venting cavity, which is in air-conducting connection with the blind-hole end of the filament cavity, has a depth between 1 μm and 20 μm. A method of manufacturing the mold insert includes providing first and second insert plates, forming a portion of a filament cavity into at least one of the front faces of the insert plates, forming a venting cavity into the front face with the filament cavity, and bringing the front faces of the plates into close abutment to form a filament cavity.

A cosmetic applicator with a bristle carrier (9), which merges into a stem (12), by way of which the bristle carrier (9) is connected to a handle (13), or into a coupling portion (11) for connecting the bristle carrier (9) to such a stem (12), wherein the bristle carrier (9) carries a multiplicity of in each case single-piece bristles (1) of length (L) and is distinguished in that the bristles (1) consist of two halves (2, 3), which are axially symmetrical relative to one another and are displaced relative to one another, and connected in one piece to one another, along their axis of symmetry (4), wherein each of the halves (2, 3) forms a planar region (6) of the bristle (1), said planar region being located in the displacement plane (5).
