In some embodiments, an apparatus includes a holder including a first surface, a second surface, a body portion in between the first surface and the second surface, and a protrusion. The first surface is configured to be coupled to a mounting surface. A magnet is disposed within the body such that a portion of the second surface is magnetically attractable to a first portion of an article. The protrusion is configured to engage a second portion of the article. The article being removably coupled to the holder when the first portion of the article is magnetically coupled against the portion of the second surface and the second portion of the article is engaged with the protrusion.

Systems, devices, and methods for applying machine learning to provide feedback related to a personal care device are described. Embodiments of the systems, devices, and methods may identify data from a device such as a razor comprising a plurality of sensors on a razor, predict one or more features such as shaving features based on the data using a machine learning model trained using data from the plurality of sensors, and provide shaving feedback based on the one or more features such as shaving features. Embodiments of the systems, devices, and methods may train a machine learning model, execute a trained machine learning model, capture and/or process data for the machine learning model, provide feedback based on the output of the trained machine learning model, or combinations thereof.

A method of stimulating hair growth on the scalp of a person's head using a device having a handle and a blade means, the method including the steps of: contacting the blade means on a first area of the scalp; moving the blade means in a continuous reciprocating motion on the scalp in a first direction and an opposite second direction for a first period of time to exfoliate skin on the first area, wherein the blade means remains in continuous contact with the scalp during the reciprocating motion until hair growth is detected in the first area.

Stands for safety shaving razors are disclosed. The stands include a pair of generally vertical members, connected by a generally U-shaped horizontal member configured to receive a portion of a razor handle, and a base configured with a cavity dimensioned to receive a portion of the razor handle.

A foldable environmentally friendly razor includes: a flat sheet with an opening at one end and a blade at the opening. The flat sheet is provided with two main folding lines extending from one end toward the other, so that a main supporting portion is formed between the two main folding lines. Two holding portions are respectively formed between the main folding lines and both sides of the flat sheet. A first folding line joins the ends of two main folding lines. Two blade face folding lines extend respectively and diagonally towards opposing left and right sides of the flat sheet from the respective junctions of the first folding line and the main folding lines, so that the two blade face folding lines and the first folding line enclose a blade face. The two holding portions and the main supporting portion form a columnar structure to provide better support.

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.

A shaving system, the system comprising a shaver including a shaver head, one or more sensors configured to detect a flow or sound of water or an orientation of the shaver and a processor configured to determine a duration and/or water usage during a shaving session and/or a rinsing session.

A method of removing hair from an underarm comprising the steps of applying an antiperspirant or deodorant composition to the underarm and shaving the underarm with a razor; wherein said antiperspirant or deodorant composition comprises a component selected from the group consisting of an antiperspirant active, a deodorant active, an odor masking fragrance, and combinations thereof; and wherein the composition comprises from about 3% to about 20%, by weight of the composition, of a blend of a nonvolatile, low viscosity silicone emollient and a high molecular weight silicone polymer.
