Description

  The present invention relates to an emulsified hair styling cosmetic.

  In order to maintain the hair style, hair styling agents such as hair sprays, hair mists, mousses, foams, hair gels, set lotions, hair creams and hair waxes are usually used. Among these, hair styling agents combining a plurality of types of oily components having a high melting point and a low melting point have been proposed (see Patent Documents 1 and 2). However, these materials have a problem that they are applied unevenly to hair because they have a lot of oil components and are very sticky and have poor elongation.

  Also, out bath treatments that contain a lot of oily components (liquid oil) that are liquid at room temperature have good elongation and can be applied evenly to the hair, but the setting power of the hair is weak, and Sustainability is also poor.

  Gels containing film-forming polymers are also used, but these have high initial setability, but once the style breaks, it is difficult to re-hair, and due to flaking, etc. There is a problem that a white film is formed.

As a specific application method for this purpose, it is preferable to lift and apply hair once. Examples of binding tools used for fixing include rubber bands, elastic bands, hairpins, hairpins, hairdressers, ribbons, etc., but anything that can be fixed can be used, and a part of the hair to be bundled can be used as a binding tool. It may be used. When binding, the entire hair may be twisted. This makes it possible to make loose hair. In addition, it is also preferable to give a soft feeling further by curling the hair tips with an iron or curler before applying the emulsified hairdressing cosmetic composition of the present invention to the hair. In addition, by partially overlapping the portion on the hair end side with respect to the fixed portion, the adhesive force can be adjusted, and the hair can be entangled to produce a soft bundle feeling and movement. At this time, after overlapping, a reverse hair may be raised to give a sense of volume. Furthermore, after processing with the emulsification type hairdressing cosmetic composition of the present invention and fixing with a binding tool or the like as described above to make hair together, waxes, sticks, foams, gels, which are more general hairdressing agents, Sustainability can be further improved by fixing the hairstyle by treatment with spray (particularly spray) or the like.
