Abstract
In a hair cosmetic containing titanium-dioxide-coated mica, titanium-dioxide-coated mica with particle diameters of 20 &mgr;m or larger is used in a proportion not more than 10% by volume in the total volume of the titanium-dioxide-coated mica so that, when applied to hair, it may not impart an unnaturally glittering impression to the hair. To improve re-dispersibility of such a hair cosmetic, a carboxyvinyl polymer and an amphoteric macromolecule may be used in combination.
