A hairstyling apparatus is shown. The apparatus includes a heated barrel with a central axis. R also includes a heating element connected with the barrel and a hair styling tool extending along a longitudinal length of the hairstyling surface and configured to rotate around the central axis of the barrel, the hairstyling tool including a comb portion comprising a plurality of bristles that protrude in a direction away from the hairstyling surface and a grooved portion comprising a plurality of grooves that expose the hairstyling surface.

Rotating dental systems and related guards and methods are disclosed. In some instances, a guard may be configured to prevent material from building up on at least a portion of the dental system. The guard may be configured to prevent materials from being discharged from the dental system. In some embodiments, the guard may also be configured to direct the flow of material along a portion of the dental system. Some guards within the scope of this disclosure may include bristles.

A head for a personal care device having a carrier including a front surface, at least one cleaning element partly embedded in the carrier and thus having an embedded cleaning element portion and a non-embedded cleaning element portion extending from the front surface of the carrier between a base end on the front surface and a free end; the embedded cleaning element portion extending from the front surface between a top end on the front surface and a bottom end, wherein the base end of the non-embedded cleaning element portion has a base end cross-sectional shape and a base end cross-sectional area, and the top end of the embedded cleaning element portion has a top end cross-sectional shape that is different to the base end cross-sectional shape and a top end cross-sectional area that is larger than the base end cross-sectional area.

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 4 a and the bottom of longer bristles 4 b 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.
