A dryer for drying hair or clothes is disclosed. The dryer includes a head and a handle attached to the head. The dryer further includes ultrasonic devices, a controller, a vacuum pump, and a reservoir. The head has a surface on which inlet holes are formed. The ultrasonic devices are positioned on the surface of the head. The ultrasonic devices produce ultrasonic vibrations that break down water molecules into mist. The controller controls an operation of the ultrasonic devices.

A dryer includes a plurality of first electronic parts including a fan and a heater, a first battery to supply power to the first electronic parts, and a first controller to control power of the first battery. The first controller detects a charging ratio of the first battery, enters a first power saving mode if the charging ratio is a threshold charging ratio or less, and limits power supplied to at least one of the plurality of first electronic parts. A holder for holding the dryer includes a plurality of second electronic parts including a plurality of contact terminals, a second battery to supply power to the second electronic parts, and a second controller to detect a charging ratio of the second battery and enter a second power saving mode to limit power supplied to at least one of the plurality of second electronic parts.

A hair grooming apparatus includes a vacuum mechanism and a vacuum chamber that is in fluid communication with the vacuum mechanism. The vacuum chamber includes a first opening positioned at a first end of the vacuum chamber with a first cross-sectional area and arranged to accommodate an insertion of a section of hair and a second opening positioned at a second and opposite end of the vacuum chamber. The vacuum chamber further includes a wall extending between the first and second openings and defining an interior bore. An air pocket is formed along a section of the interior bore extending from a first location located proximate to the first opening with a second cross-sectional area to a second location positioned between the first location and the second opening with a third cross-sectional area. The second cross-sectional area is greater than both the first cross-sectional area and the third cross-sectional area.

In various embodiments, a hair treatment device is provided. The hair treatment device can have a device body, at least one sensor arranged in or on the device body for detecting a hair condition parameter, and an electronic circuit device arranged in or on the device body. The electronic circuit device can be coupled to the at least one sensor for receiving the detected hair condition parameter, and the electronic circuit device can be configured, based on the received detected hair condition parameter, to control at least one hair treatment parameter and/or to dose at least one hair treatment agent and/or to provide a hair treatment recommendation.

A computer system receives user-specified settings for a custom formulation of a personal care product, obtains manufacturing parameters for the custom formulation based at least on part on the user-specified settings for the custom formulation; and transmits the manufacturing parameters to a manufacturing computer system. The manufacturing parameters are configured to initiate or guide a manufacturing process to produce the custom formulation of the personal care product. The computer system also receives user-specified settings for a personal care device having at least one computer-controlled component, obtains operational parameters for the personal care device based at least in part on the user-specified settings for the personal care device; and transmits the operational parameters to a remote computing device in communication with the personal care device. The operational parameters are configured to modify at least one operational characteristic of the at least one computer-controlled component of the personal care device.
