  When a hair color composition is used, it is possible to obtain a darker, more dyeable (lighter) color tone on the hair. The hair color composition is suitable for dyeing. Hair color composition has good fastness to natural factors (light, sweating, etc.) or chemical factors (shampoo, permanent wave treatment, etc.) while giving good cosmetic properties and low selectivity. A strong and colorful (brilliant) color tone can be obtained. The hair color composition does not run off and thus is a dyeing composition ready for use that is well held at the site of application.

  The hair color composition exhibits very good storage stability. When the hair color composition is used, it is possible to give particularly good gloss after drying to the hair, and it is possible to impart good combing property, cohesiveness, and moist feeling. Furthermore, the slipperiness at the time of washing and rinsing is excellent. The hair color composition can impart a smooth and moist feel to the hair, especially when it is washed and rinsed with excellent slipping feeling against damaged hair, and gives an excellent gloss feeling to dry hair. Can do.

  In addition, when a hair color composition is used, the fingering property, combing property and the like are good for the hair.

  The hair color composition is suitable as a composition for hair conditioning. The hair color composition can improve the color while maintaining low irritation. The hair color composition is less irritating to the skin and can give good lightness to the hair. The brightness after the hair dyeing treatment can be further improved. When a hair color preparation containing a hair color composition is used, there are cosmetic effects such as the ability to improve the hair to a physiologically healthy state.

  If the hair color composition is a cream or the like, the hair color composition may further contain an oil phase component. The hair color composition may be distributed and used as a final product as it is, or may be used in a hair color cosmetic (a form such as a hair color agent) containing the hair color composition. . Examples of such hair coloring agents include preparations such as gels and lotions.

  The hair color composition contains a hydrophobically modified alkyl cellulose, so that the hair color composition has good elongation and is easy to apply to hair.
