A Bharatnatyam headgear comprising a wearable hair net, the hair net being pliable and expandable to be worn over a dancer's head and covering the head, the wearable hair net matching a color of the dancer's hair. A circular piece is affixed to the hair net. The circular piece is capable of being positioned in a middle of a forehead at a forward end of the hair partition of the dancer. A forehead piece is affixed to the hair net, the forehead piece extending in a horizontal direction capable of being positioned to coincide with a hairline in a left and right direction and extending at least beyond eyebrows of the dancer. A vertical piece is affixed to the hair net, the vertical piece being attached to the circular piece and extending across a middle of the head to cover the hair partition.

A human hair fiber treatment agent for treating human hair fibers having free ends at both ends, comprising the following components (A) to (C) in the formulation thereof: (A): formaldehyde or hydrate thereof; (B): melamine derivative represented by the formula (1):

##STR00001##

wherein R.sup.1 to R.sup.3 are the same or different and each represent a hydrogen atom, a hydroxymethylamino group, a hydroxy group, a halogen atom, a phenyl group, a linear or branched alkyl group or alkenyl group having 1 or more and 6 or less carbon atoms, or a linear or branched alkoxy group or alkenyloxy group having 1 or more and 6 or less carbon atoms; and (C): water.

A head scarf includes a scarf section, lace section and hair section. The scarf section has top and bottom sides and is constructed of a first material. The scarf section contains an outer periphery where an engagement portion lies. The lace section is constructed of a second material and includes a plurality of hair fibers extending therefrom forming the hair section. The lace section is positioned on the engagement portion substantially near the outer periphery of the scarf and operably coupled to the engagement portion.

Provided is artificial hair including chemical fibers and a fiber treatment composition that is adhered to the surfaces of the chemical fibers. The fiber treatment composition may include an oxazoline group-containing acrylic resin and an organic-modified silicone oil. The oxazoline group-containing acrylic resin may have a main chain that includes a (meth)acrylic acid ester and styrene.

Provided are: a wig base or a wig cap, which is capable of improving wearability and fit feeling to the head; and a wig including the wig base or the wig cap.

A wig 100 includes a wig base 1 formed into a cap shape capable of covering the entire head from wearer's ears and nape, in which a bag-shaped pad portion 2 is integrally provided on an occipital region 6 of a back surface of this wig base 1. The bag-shaped pad portion 2 is formed into a substantially fan shape having a hollowed lower portion, and an inside of the pad portion 2 is able to be filled with polyurethane foam 8. At least a part of the pad portion 2 is sewn on the back surface of the wig base 1 so as to be located on a nape hollow 9 (a hollowed portion from the occipital region to the nape) of the wearer's occipital region, and is brought into contact with the nape hollow 9.

A human hair fiber treatment agent comprised of one or more compositions for treating human hair fibers having free ends at both ends, wherein the human hair fiber treatment agent comprises the following components (A) to (C) in the formulation thereof: (A): at least one formaldehyde derivative selected from the group consisting of formaldehyde, and the like; (B): phenol compound(s) having electron-donating group(s) on at least one of the meta positions and having hydrogen atom(s) on at least one of the ortho positions and the para position, with the proviso that the electron-donating group at the meta position optionally forms, together with a carbon atom attached thereto, a benzene ring optionally substituted with hydroxy group(s); and (C): water.
