Increasingly, individuals use online social network platforms (also referred to as Internet-based social networks) to access a variety of information and content, such as articles on various topics, updates related to a user and individuals within the user's network, friend suggestions, advertisements, news stories, and the like. Among other things, embodiments of the present disclosure can be used to help identify users of a social network based on various information.

The present invention relates to an applicator brush (1) for applying a cosmetic, make-up or care product to human keratin materials, especially the eyebrows, comprising a handle (4) which extends along a longitudinal axis (X) and, at the distal end thereof, an applicator head (2) having distal (2c) and proximal ends, and carrying a tuft (3) of bristles (6), the free ends (6a) of which define an applicator surface (5) that is convex towards the outside, in which applicator the applicator head (2) extends along a longitudinal axis (Y) that is not parallel to the longitudinal axis (X) of the handle (4), and wherein the tuft (3) of bristles (6) is arranged such that the transverse dimension of the applicator surface (5) increases towards the distal end (2c) of the applicator head (2), passing through a maximum, before decreasing from the location at which the transverse dimension is maximum towards the distal end (2c), the maximum of the transverse dimension of the applicator surface (5) being closer to the proximal end of the applicator head (2) than to the distal end (2c) thereof.

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.

In one aspect, the present disclosure provides a makeup brush. The makeup brush may include a brush portion secured to a forward end of a ferrule. The brush portion may include a plurality of tuft groups, where each tuft group is formed by a plurality of bristles. The tuft groups may form a concave profile at a working end of the makeup brush, and the concave profile may be configured to match a profile of human eyelashes.

A tuft picker for a tuft-picking device has a working surface having a tuft-picking notch with a depth, a width, and an opening. First and second projections reduce the opening of the notch versus an inner width. At least one top of the first and/or second projection is located off-site the working surface of the tuft picker and inside of the notch. A distance from the at least one top to the working surface of the tuft picker is in the range of from 0.05 mm to 0.5 mm, and an angle between the working surface of the tuft picker and a line of reflection symmetry crossing the at least one top is from 1 to 45.

A toothbrush comprises a handle; a head connected to the handle; and a plurality of bristles, respective ones of the plurality of bristles including a first end having a tapered first tip, a second end having a tapered second tip, and a substantially cylindrical shaft extending between the first end and the second end. Respective ones of the plurality of bristles are fastened to the head by a fastener at a fastening point along the shaft, the fastening point being located nearer to the second end than to the first end such that the first end extends from a surface of the head to a first height and the second end extends from the surface of the head to a second height. A difference between the first height and the second height is greater than or equal to 2.25 mm.
