Description

  The present invention relates to a powder solid hair composition, a powder solid hair cosmetic comprising the composition and a container, a method for producing the cosmetic, and a hair styling method using the cosmetic.

  As cosmetics for styling hair, there are liquid, gel-like, foam-like, or mist-like hair cosmetics in which a film-forming resin is blended as a hair styling main functional ingredient (see, for example, Patent Documents 1 to 4). . In addition, there are cream-like or wax-like hair cosmetics in which oil agents such as waxes and hydrocarbon oils are blended as hair styling main functional ingredients (see, for example, Patent Documents 5 to 6). At present, cosmetics for hair containing a film-forming resin or an oil are mainly used.

  However, hair cosmetics formulated with conventional film-forming resins or oils can fully exhibit excellent hair-styling functions, but are difficult to impart a sticky feeling and a natural texture. There's a problem. Various attempts have been made so far to solve the above-described problems.

  On the other hand, there are various hair styling methods for each dosage form for hair styling methods using hair cosmetics, and in general, methods such as combing hair, methods using the palm and fingers, etc. are tried. ing.

  However, when a hair cosmetic is used, the method of performing hair shaping using a comb has the problem that although the entire hair can be easily shaped, the hair cannot be fully sized. In addition, when using hair cosmetics, it is possible to perform hair styling with the palms and fingers instead of combs, but it is possible to give sufficient hair to the details, but if too much cosmetic is applied, the sticky feeling and heavy hair bundles Since a feeling arises, there exists a problem that it cannot perform hairdressing simply.

  Thus, with conventional hair cosmetics, it is difficult to provide sufficient hair conditioning simply and in detail. In particular, when going outside, it is still more difficult to simply and sufficiently adjust the hair in detail, and it is not possible to easily adjust the hair. In view of such cosmetics for hair and the current situation surrounding it, development of a cosmetic for hair that is a new dosage form and that can easily perform hair styling is desired.
