Disclosed are a no-glue cosmetic brush and its manufacturing method. The manufacturing method of the no-glue cosmetic brush of the present invention includes the steps of forming a shape of a brush hair by using a plurality of hair members; providing a fusion portion by applying heat to a lower end of the shaped brush hair; processing the brush hair in a desired shape by pressing a hair fixing tube in a region to which the fusion portion is inserted; and coupling the brush hair to the hair fixing tube by pressing the hair fixing tube after inserting the brush hair to the hair fixing tube.

Example aspects of a brush assembly and a method for providing a brush assembly are disclosed. The brush assembly can comprise a plurality of elongate primary brush bristles, each of the primary brush bristles defining a star-shaped transverse cross section, each of the primary brush bristles defining five substantially parallel outer edges and five substantially parallel inner edges extending along a length of the primary brush bristle; and a ferrule attached to the plurality of primary brush bristles.

A method for manufacturing a toothbrush having a bristle carrier made of a thermoplastic material with a front side and a rear side is provided. At least one recess formed as a blind hole in the bristle carrier extends from the front side in the bristle carrier, and holds at least one bristle. The at least one bristle is received in a receiving opening of a tool melted to form a thickening at its attachment-side end and inserted with its attachment-side end into the recess. The thermoplastic material is heated and, by pressing the tool against the front side of the bristle carrier, is deformed such that the thermoplastic material is displaced radially inwards into the recess, at least in the region of an edge surrounding the recess, for the form-fitting sealing of the thickening, in that a projection provided radially adjacent to the recess is pressed into the thermoplastic material.
