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.

Implementations of a hair extension washboard are provided. In some implementations, the hair extension washboard comprises a hair extensions board, a hair clip assembly, and a board support. In some implementations, the hair extension washboard further comprises a hair drying enclosure. In some implementations, the hair extension washboard also comprises surface connectors. In some implementations, a method of using the hair extension washboard comprises positioning the hair extension washboard in a sink or other suitable location, holding hair extensions with the hair extension washboard, and washing, coloring, drying, etc. the hair extensions while held by the hair extension washboard.

A contourable product for absorbing moisture includes a main sheet comprising an absorbent material. A number of sides of the main sheet is more than four, with the main sheet defined by a polygonal shape. The main sheet is movable between an unwrapped position and a wrapped position. In the unwrapped position, the main sheet is completely unfolded and substantially flat. In the wrapped position, the main sheet is contoured to secure to and wrap around a human head and extend around head hair of the human head.

A motor includes a bearing having a rolling member disposed between an inner ring and an outer ring, a spring connected to the outer ring, and a pusher connected to the spring and configured to move to a first position spaced apart from the inner ring by the spring. The pusher is further configured to move to a second position at which friction with the inner ring is caused by a pressure of air. The inner ring is spaced apart from the rotating shaft by a gap between the inner ring and the rotating shaft when the pusher is at the second position.

Embodiments and technologies described herein generally relate to systems and methods for drying hair. In some embodiments, the drying can be accomplished without using a heat source. In some embodiments, the drying can be accomplished using a mechanical motion or mechanical device.

A hair-drying comb and a combined comb are provided. The combined comb includes a comb plate, a handle, and at least two hair-drying combs. The comb plate is integrated with the handle, and the hair-drying combs are arranged on the comb plate at intervals along a width direction of the comb plate. Specifically, the hair-drying comb includes a comb body and a plurality of teeth. The comb body is C-shaped and opened with a C-shaped groove with a plurality of teeth disposed, the teeth are arranged at intervals along a length direction of the comb body, and both sides of each tooth are respectively provided with an absorbent strip. Due to the absorbent strips, while the hair-drying comb combs hair, the absorbent strips absorbs most of the water, and the combined comb can contact the hair more, comb the hair faster and absorb the water from the hair faster.
