Process and device for making hair buns is disclosed. The invention described here reduces the effort and shortens the amount of time necessary to form a hair bun that remains in place for an extended period of time without the use of bobby pins or other hairpin devices.

A kit for illuminating the hair of a user, comprises: at least one light emitting diode emitting light at a wavelength, an optical fiber (26) coupled to the or each light emitting diode, a fastening element (22) to fasten the or each light emitting diode and/or the optical fiber to the hair of a user, The kit comprises a fluorescent material (30), the optical fiber (26) being configured to transmit the light emitted by the or each light emitting diode to the fluorescent material (30), the fluorescent material (30) being excited at the wavelength of the or each light emitting diode.

A hair styling charm is provided consisting of two synchronized shell members pivotally connected and capable of moving between open and closed positions. In the closed position, the charm features first and second openings formed between the shells. Each shell has a concave inner surface lined with a resilient silicone pad, featuring complementary ridges. These ridges engage when the charm is closed, effectively altering the direction of hair passing through it. Silicone pads, secured within the shell members by pegs and holes, are designed to bulge outwardly, shifting from concave to a more planar shape as they interact with hair.

A hair accessary according to the present disclosure comprises: a body part including a first body part and a second body part capable of being mutually separated from and coupled to each other; a first decoration part covering at least a portion of an outer surface of the first body part; and a second decoration part covering at least a portion of an outer surface of the second body part; wherein the body part has an inner surface having a closed loop structure formed through coupling of the first body part and the second body part.

A weaving tool comprising a first part and a second part, in which a first end of said first part is connected to a first end of said second part by a hinge, in which said first part comprises a first comb portion with first teeth extending away from said hinge, and in which said second part comprises a second comb portion with second teeth extending away from said hinge, in which said first part and said second part are movable about an axis of said hinge between a first position in which said first comb portion and said second comb portion are substantially parallel, and a second position in which said first comb portion and said second comb portion are displaced from one another about said axis.

A hair treatment apparatus includes a base and a sidewall in direct contact with and extending from the base. The base and sidewall define a cavity configured for receiving a liquid. The hair treatment apparatus further includes a lid coupled to the sidewall opposite to the base, the lid defining an adjustable aperture configured for receiving a portion of hair for treatment in the liquid. The lid includes a first ring, a plurality of plates, and a second ring. The first ring is configured to releasably engage the sidewall and define a central axis. The plurality of plates extend from the first ring toward an aperture, each of the plurality of plates includes a pin. The second ring defines a plurality of slots to receive the pins. Rotation of the second ring causes the plurality of plates to extend toward the longitudinal axis to reduce the diameter of the aperture.

A system for optically acquiring data from hair comprises a hair-holder including: upper and lower plate assemblies respectively having downward-facing and upward-facing opposing surfaces defining a gap therebetween, the lower plate assembly having a window-void therein, the upper plate assembly further comprising a sideward-facing sample-thickness-regulating surface above the gap; and an alignment-wall mechanically coupled to both plate assemblies and having a side-facing alignment surface within gap or sideward-facing into the gap, the alignment surface being straight along a longitudinal direction parallel to both of the opposing surfaces, the hair-holder being configured so that: when an externally-tensioned sample of hair is loaded onto the hair-holder by laterally moving the sample towards the alignment surface, a presence of the sideward-facing sample-thickness-regulating surface regulates an amount of hair permitted to enter the gap, thereby regulating a thickness of hair above the window-void to at least 0.5 mm and at most 2 mm, and after the loading and after release of the external tension, static friction applied by the side-facing alignment surface upon shafts of the hair sample maintain alignment of hair above the window-void.

A hair tie extraction implement adapted to remove hair ties and/or elastomeric bands entangled with hair from the head of a wearer. The hair tie extraction implement comprises a grippable shank, a hook, a razor blade, and an outwardly rising bill.

The hairstyle preserving liner is a hairstyle preserving liner that is attached to the inside of a head covering and fitted to the head of a human body, and includes: a liner main body; and multiple protruding members formed on the surface of the liner main body facing to the head. In addition, in the hairstyle preserving liner, the heights of the multiple protruding members are set such that the radially innermost protruding members around the central part of the liner main body are highest, and the radially outermost protruding members are lowest, and the liner main body is formed of a flexible material and has multiple tongue-shaped parts that in an expanded state, extend circumferentially at regular intervals and radially outward around the central part facing to the top area of the head of the human body.
