A shaping apparatus configured to use a shaping material to form a shaped product on a target placed on a shaping stage. The shaping apparatus includes a discharger configured to discharge the shaping material onto the target; and a processor configured to control a distance between the target and the discharger based on a characteristic value of the target.

A core-sheath conjugate fiber for artificial hair includes a core part and a sheath part. The core-sheath conjugate fiber for artificial hair has a flat two-lobed cross sectional shape or an elliptical cross sectional shape, and has a core-to-sheath area ratio of core:sheath=3:7 to 8:2 in a fiber cross section. The sheath part contains a polyamide-based resin composition containing a polyamide-based resin. The core part has a modified flat two-lobed cross sectional shape or a modified elliptical cross sectional shape including a pair of protrusions protruding from the center side toward the outer circumferential side along a minor axis direction of the fiber cross section. A core-sheath conjugate fiber for artificial hair having a touch close to that of human hair, an excellent combing property, and a good curl setting property, a hair ornament product including the same, and a method for producing the same are provided.

The present invention is directed towards providing a device for displaying and demonstrating hair switches. The device is useful for showing the benefits and effects of hair products on the hair in an aesthetical pleasing manner. The device can be readily assembled and disassembled for efficient storage and transportation and it enables a rapid attachment and removal of a hair switch for efficient product evaluation, display and demonstration.

A core-sheath conjugate fiber for artificial hair has a core-sheath structure including a core and a sheath covering the core. The core is composed of a core resin composition containing a polyester-based resin, and the sheath is composed of a sheath resin composition containing a polyamide-based resin. The core resin composition contains a bromine-based flame retardant and a flame retardant auxiliary. The sheath resin composition contains a phosphorus-based flame retardant. The phosphorus-based flame retardant contains at least one selected from the group consisting of a zinc phosphinate and a condensed phosphate ester compound.

A hair replacement assembly for simulating a hairline includes a net, which has a first face that is selectively engageable to a scalp of a user so that the net is removably engaged to the scalp. A plurality of filaments is engaged to the net and extends from a second face of the net. The filaments mimic hair of the user or a wig positioned on a head of the user. The net is one of a plurality of nets, with each net having a respective shape so that the plurality of nets comprises nets having a variety of shapes. Each net is shaped substantially complementarily to an associated target area on the scalp of the user so that the plurality of nets can cover a plurality of target areas. The filaments blend the target areas with the hair of the user or the wig.

A head mold for a wig may include a head mold body and an information pattern. The head mold body may be formed using a stack type three-dimensional (3D) printer into which head information of a user may be inputted. The information pattern may be provided to the head mold body to indicate information of the wig. The head mold may be manufactured using the stack type 3D printer to prevent a generation of dusts during manufacturing the head mold. Further, the stack type 3D printer may have a low price compared to a milling machine to reduce an initial investment cost for manufacturing the head mold.

The Weave Assist is an all inclusive flat but slighlty elevated weaving device used by stylist and seamstresses to cut out the stop and start of needle prepping. It is also used to make and correct wig units in a portable all inclusive design that has a simple blade for your cutting needs while prepping or wig making. It also has feet to help the device stay in place while working. The device the has a base, spool, spool holder, storage box, cutting blade, magnet, and half moon holder to attach block bead if not attaching directly to the base. The weave assist allows needle prep for up to 2½ clients. The lifespan of the weave assist is 3-7 years with proper use. The device can eliminate one less step in the weaving process allowing work to process without breaks and complete clients in a timely manner.

Methods of making a wig are presented where the wig has a top portion that defines an opening corresponding to the wearer's part, the top portion being composed of a fabric and having wig hairs attached to the top portion. Wig clips on the underside of the top portion may attach the wig to the wearer's natural hair on the opposing sides of the wearer's part. The methods address manufacture of the wig and also address modifying an existing wig to create the wig.
