A brush comprises a plurality of filaments having a crimp structure and a J structure to provide a full distribution of filaments at an end surface of the brush, wherein the crimp structure of a majority of the filaments is configured with a period length of 2 mm to 5 mm and a peak to peak length of not greater than 0.8 mm, and the J structure is configured with a long length about 0.02 inches to about 1.2 inches, and a difference between the long length and a short length is about 0.2 inches to about 0.5 inches.

An oral care implement having a head with a bristle bearing surface. The oral care implement may include a central bristle tuft extending from a central portion of the bristle bearing surface, the central bristle tuft terminating in a domed distal surface. Furthermore, the oral care implement may include a plurality of perimetric bristle tufts extending from the bristle bearing surface and arranged to circumferentially surround the central bristle tuft. Each of the perimetric bristle tufts may have an inclined distal surface that slopes downward towards the central bristle tuft. The bristle bearing surface of the head may have a total surface area (TSA), and the toothbrush may include a tooth cleaning element field having X number of tooth cleaning elements that collectively occupy a total cleaning element area (TCEA) such that $\frac{1}{X}\frac{TCEA}{TSA}=Z$
and Z is in a range of 0.04 to 0.065.

The brush head of the toothbrush has filaments that are pointed at one end and led through clearances in the bristle carrier. These filaments have a length of about 10-20 mm. The tips of the pointed filaments produce a height profile other than that of a plane and the ends of the pointed filaments that are remote from the tips are melted.

A lice brush includes a body that supports a plurality of bristles. The body also includes a handle. One or more of the plurality of bristles is configured for use in brushing a user's hair for lice. In particular, one or more of the bristles includes recesses, grooves, indentations, notches, pits or similar inwardly-extending spaces configured to facilitate removal of lice as the bristles pass through the hair. Multiple bristles can be provided in a bristle unit and multiple bristle units can be employed in a bristle assembly of the brush.

An oral care implement having a head with a bristle bearing surface. The oral care implement may include a central bristle tuft extending from a central portion of the bristle bearing surface. The oral care implement may include a plurality of perimetric bristle tufts extending from the bristle bearing surface and arranged to circumferentially surround the central bristle tuft. The perimetric bristle tufts may have different shapes from one another.

An oral care implement (100) including at least multi-component bristle. The oral care implement (100) comprises a handle (120); a head (110) coupled to the handle (120); at least one bristle tuft extending from the head, the at least one bristle tuft comprises at least one multi-component bristle (200) comprising coextruded core (210) and sheath components (220), the sheath component (220) surrounding a first portion (215) of the core component (210), and a second portion (216) of the core component (210) protruding from the sheath component (220) at a tip portion (230) of the multi-component bristle (200); the sheath component (220) comprises a first plastic and a first oral care additive; the core component (210) comprises a second plastic and a second oral care additive, wherein the first oral care additive is different than the second oral care additive.

A backcombing brush for backcombing hair includes an array of bristles 4. Each bristle extends from a base to a free end and two lengths of bristle are provided. Shorter bristles 4a and the bottom of longer bristles 4b carry out backcombing, whilst the longer bristles smooth hair, or untangle knots/tangles in the hair to reduce the level of backcombing. The long bristles have a relatively wide first portion 5, towards the base of the bristle, and a relatively narrow second portion 6, towards the free end of the bristle. The bristles are arranged such that bristles in one row neither extend between adjacent bristles in an adjacent row nor partially occlude the space between bristles in an adjacent row.

A combination sticky roller and brush, includes a frame, a cylindrical roller, a handle, and at least one groove defined in the frame, parallel to the roller axis of rotation. The at least one groove is to engage and selectably retain a brush head. The frame and the brush head together define a latching mechanism for selectably latching the brush head in a service position and for resisting a predetermined threshold disengaging force. The cylindrical roller has a washable sticky layer defined at a circumferential surface of the cylindrical roller.

A pet grooming tool for grooming a furry pet. The pet grooming tool includes a handle portion and at least one pet engageable portion. The handle portion has a head portion, and each pet engageable portion is secured to the head portion. The pet engageable portion comprises a plurality of teeth arranged in a row and a plurality of edge segments with a gap between each adjacent pair of teeth.
