A handheld personal care device according to the present disclosure includes: an operation switch configured to change a treatment operation of an operation unit; a sensor electrode configured to cause a change in capacitance depending on whether or not the grip unit is grasped; and a control device electrically connected to the operation switch and the sensor electrode and configured to control the treatment operation of the operation unit. The control device includes: a grasp detector configured to detect that the grip unit is grasped based on a change in capacitance of the sensor electrode; and a change permission part configured to permit the operation switch to change the treatment operation of the operation unit when the change permission part receives, from the grasp detector, grasp information indicating that the grip unit is grasped.

Devices and methods for styling hair, and in particular, to devices and methods for styling hair using electrolysis are described herein. A method for styling hair includes arranging a section of hair between a first electrode and a second electrode. The section of hair is contacted with an electrolyte before being arranged between the first and second electrodes, after being arranged between the first and second electrodes, and/or concurrently with being arranged between the first and second electrodes. The method further includes causing the first electrode to have a first negative potential, and causing the second electrode to have a second potential, such that the absolute value of the first negative potential is greater than the absolute value of the second potential, and such that the difference in electrical potential between the first electrode and the second electrode creates an electrolysis zone between the first electrode and the second electrode.

A hair styling appliance includes first and second heating plates operatively connected for pivotal displacement relative to one another such that a hair segment positioned between them can be styled. A glide-speed sensing system generates an output having a relation to a speed with which the hair segment is displaced relative to the first and second heating plates. A glide-speed indicating system can communicate feedback to a user, based on the output, such as an indication of a glide speed of the hair styling appliance relative to the associated hair segment. A user input device can receive an input from the user regarding a hair-type classification and/or a hair-condition classification and generate a hair-related output having a relation to the input from the user. A processor communicatively coupled with the user input device can be programmed to determine a predetermined maximum treatment temperature and/or a predetermined glide speed range, based at least partially on the hair-related output from the user input device.

The present invention relates to a hair root volumizing styler. which curls hair to add volume thereto, comprising: a styler body having a handle formed on one portion thereof to provide a grippy feeling; heating members provided on one portion of the styler body to provide heat sources; rod-shaped volumizing members provide on the opposite side of the handle, on the styler body; and heat-blocking members, which block heat generated from the volumizing members while encompassing portions of the lower parts of the volumizing members, so as to protect the scalp, wherein the volumizing members are manufactured in a set size and are separably coupled to the styler body.

A detachable hair brush apparatus is disclosed. The hair brush apparatus may comprise a handle with elongated metal extension rods at one end and at least one hollow brush head for insertion around the metal extension rods. In a locked position, the metal extension rods extend substantially through a base of the brush head. At least one button may be located on said handle for releasing the mechanical locking engagement. Torque provided by a user of the hair brush apparatus is absorbed by the metal extension rods of the hair brush handle. In this way, functional separation of two distinct systems is provided for, namely the function of attaching and the function of absorbing torque. This will make for increased robustness of each system. In a preferred embodiment, neither the handle nor the at least one hollow brush head comprises a magnet for coupling.

A spacing accessory is selectively deployable with a hair treatment tool. In a first aspect, an assembly includes (1) a hair treatment tool with opposed heating surfaces disposed on two arms configured to open, to allow hair to be inserted between the heating surfaces, and close, to press hair between the heating surfaces, and (2) a spacing accessory selectively deployable to maintain the heating surfaces in a spaced relationship, when the arms are closed. In a second aspect, a spacing accessory is configured for removable attachment to a hair treatment tool of the aforementioned type, with the spacing accessory including a spacing member configured to extend between the two arms of the tool to maintain a spaced relationship between the heating surfaces when the arms are closed.
