<p>[Problem] To provide an aerosol-type foamy oxidative hair dye composition which ensures excellent uniform dyeing, hair dyeing power and operation and which can well suppress sags and runs. [Solution] An aerosol-type foamy oxidative hair dye composition which is used in a manner such that at the time of application, multiple components are discharged and mixed, wherein: the initial foam specific gravity of a mixture of the multiple components is 0.03 to 0.18; and the foam specific gravity change as calculated from the foam specific gravity determined after the lapse of 5 minutes from the mixing and the initial foam specific gravity is 100 to 150%.</p> |
