A trimming assembly for dreadlocks comprises a handle. A cutting head is operatively connected to the handle. The cutting head comprises a cutting head body defining a receptacle at a radial end thereof. The receptacle is structured to receive a dreadlock. A blade protector is positioned axially within the receptacle. A curvature of the blade protector corresponds to a curvature of an inner wall of the receptacle. A blade is interposed between the blade protector and the inner wall. The blade defines a cutting edge at an axial end thereof proximate to the handle. The cutting edge is structured to cut loose hair protruding outwards from the dreadlock as the cutting head is moved along the dreadlock.

An apparatus for testing a razor blade comprises a base, a material support table, a material sample, a transport carriage, a blade retention assembly, and a razor blade. The material support table is supported by the base. The transport carriage is movably coupled with the base and is movable with respect to the material support table between a start position and an end position. The blade retention assembly is movably coupled with the transport carriage and is movable with respect to the material support table between a blade-engaged position and a blade disengaged position. The blade retention assembly is movable together with the transport carriage between the start position and the end position. The blade is releasably attached to the blade retention assembly. The razor blade contacts the material sample when the blade retention assembly is in the blade-engaged position. Methods are also provided.

There is provided a frame unit (10, 30, 60, 70) for use in a hair clipping system. The frame unit comprises a frame (110, 310, 610, 710); a first ear portion (120, 320, 620, 720) for supporting the frame at the first ear of the subject; at least one of a nose portion (140, 340, 640, 740) for supporting the frame on the nose of the subject and a second ear portion (130, 330, 630) for supporting the frame at the second ear of the subject. The frame interconnects the first ear portion and the at least one of the nose portion and the second ear portion. Also, the frame extends below a line interconnecting the first ear portion and the at least one of the nose portion and the second ear portion while in use on a subject so as to enable access to the side of the face of the subject by a hair clipping unit.

A hair trimming device arranged to detect positions of the hair trimming device in relation to a client's head and to adjust its trimming length automatically and dynamically according to preprogrammed values at any given point during a hair trimming session.

A razor assembly comprising a first razor head member; a second razor head member; a handle; and wherein the first razor head member and the second razor head member are pivotable about each other.

A razor having a handle and blade cartridge containing one or more blades includes a battery power source and a heating system powered by the battery source for heating the one or more blades and/or a heating element on the blade cartridge. The blade cartridge further includes a strip of lubricating material thereon that is heated by the heating system when the blades and/or heating element warm up. As the strip of lubricating material is warmed up, it provides a release of extra lubricating chemicals, including fats or other lubricating agents. This helps to provide a more comfortable shave while also protecting the user's skin both during shaving and after shaving.

A fluid discharger and applicator device for uniform distribution or application of the fluid for treating the skin or any surface is disclosed. The fluid discharger and applicator device comprises a handle, a dispenser connector and a dispenser member. The handle of the fluid discharger and applicator device is defined with a cavity to store a fluid. The handle is further defined with a dispenser end configured to dispense the fluid stored within the cavity of the handle. The dispenser connector of the fluid discharger and applicator device is removably fastened to the dispenser end of the handle. The dispenser connector is configured to transfer the fluid extruded from the cavity of the handle on the dispenser member, which is operably attached to the dispenser connector. The dispenser member of the fluid discharger and applicator device is configured to apply the fluid on skin of a user.

An intelligent head cover includes: multiple sensors, a hairstyle processing component and a controller; where the multiple sensors are configured to acquire sensory data related to a user, the controller is configured to control the hairstyle processing component to perform a hairstyle processing action based on a control instruction. The control instruction is generated based on the sensory data.

Consumer products, e.g., shaving systems and toothbrushes, are disclosed which have a replaceable portion, e.g., a shaving assembly or a toothbrush head, that is removably mounted on a handle. The consumer products described herein include keyed structures on the handle and replaceable portion, the relative placement of which creates a unique interaction between the two parts. This unique interaction may, for example, be used to provide a dedicated attachment system for each specific customer of the manufacturer of the consumer product.

There is provided a method of manufacturing a cutting element for use in a hair cutting device, the cutting element comprising an optical waveguide, the method comprising providing a preform for an optical waveguide, the preform comprising a core and an outer layer, wherein the outer layer is arranged around the core along the length of the core; forming a shaped preform by removing a portion of the outer layer along the length of the core to expose part of the core, wherein a remaining portion of the outer layer is a support structure for the core; heating the shaped preform; and pulling the shaped preform in the direction of the axis of the core to reduce the cross-section of the shaped preform and form the optical waveguide. Also provided is a cutting element manufactured according to the above method and a cutting element for use in a hair cutting device, the cutting element comprising an optical waveguide comprising a core and a support structure, wherein the support structure contacts the core along the length of the core to support the core, and wherein part of the core is exposed along the length of the core to form a cutting face for contacting hair. The thickness of the support structure tapers linearly or non-linearly from a thin side at which the support structure contacts the core to a thick side.
