Method for improving the stability in air of a hair dye concentrate

A hair treatment composition is disclosed. The composition comprises: (A) a branched-type quaternary ammonium salt, (B) one or more agents selected from the group consisting of oxidizing agents, reducing agents, and dyeing agents, and (C) a higher alcohol having a branched ratio of 1-50%. The composition is directed to hair perming, hair dyeing, and the like, and exhibits excellent hair protecting and hair conditioning effects even under severe conditions. It features good handling performance, e.g. the capability of preventing running of the liquid and of providing superior spreadability. The excellent conditioning effect lasts for a long period of time even after repeated washing.

Hair treatment composition

A dye composition for keratinous fibers is disclosed. The composition comprises a developing substance and, as a coupling substance, a 3,5-diaminopyridine derivative of the following formula (I), ##STR1## wherein R.sup.1 is an alkoxy group or a group ##STR2## wherein R.sup.2 and R.sup.3 may be the same or different and individually represents a hydrogen atom or a hydroxyalkyl group, R.sup.4 a hydroxy, alkoxy, or hydroxyalkyl group, and n is a number of 1-4; or a salt thereof. The composition is capable of dyeing keratinous fibers such as hairs in blue color with a high vividness and with resistances to the light, color change, and discoloration due to shampooing.

Dye composition for keratinous fibers

The invention relates to an improved hairbrush of the type in which a plurality of bristles are implanted into each bristle implantation hole formed on an implantation surface. Each implantation hole is divided into a plurality of compartments, bristles are implanted in pairs such that one or two bristles are implanted into each compartment, the gap between the bristles of each pair implanted into the separate but adjacent compartments is kept within the range of 0.4 to 1.2 mm, and the boundary lines between adjacent compartments are aligned geometrically.
