Abstract: A hair growth promotor which is an ethanol or aqueous ethanol preparation comprising, as active ingredients for a hair growth promotor, (A) at least one compound selected from fatty acids having a chain length of an odd number of carbon atoms, the derivatives of the fatty acids, aliphatic alcohols having a chain length of an odd number of carbon atoms and the derivatives of the aliphatic alcohols and (B) at least one selected from 6-benzylaminopurine and/or the derivatives thereof represented by the following Formula (I), wherein it further comprises (C) at least one of polyglycerin fatty acid esters and (D) at least one of sorbitan fatty acid esters: in Formula (I), R1 and R2 are defined. The hair growth promotor can have an excellent hair growth effect and can provide an excellent stabilization effect at low temperature and can provide good feeling having no stickiness.

Abstract: External preparations comprising, as active ingredients, kojic acid or a derivative thereof which also contain an ultraviolet absorber, .beta.-cyclodextrin and ethylenediaminetetraacetic acid and have a controlled pH in the range from 4.0 to 5.0 show little discoloration during storage. In addition, discoloration of the preparation applied to the skin due to ultraviolet rays and other causes is also minimized, thus eliminating the trouble of contaminating clothes and other surrounding objects.

Abstract: Disclosed is a hair-dyeing composition comprising one or more tannins and one or more compounds selected from water-soluble zinc, copper, tin, magnesium and aluminum salts. The composition may be in the form of either a one-solution-type or a two-solution-type. The composition may dye hair in any desired color, and the color fastness of the dyed hair is excellent.

Abstract: Disclosed is a hair-dyeing composition comprising geraniintannin and a water-soluble iron salt and optionally containing one or more selected from tannic acid, L-cysteine and salts thereof, sodium hydrogen sulfite, sodium sulfite, hydrolyzed product of collagen and resins for hair. The composition may be in the form of either a one-solution-type or a two-solution-type. Also disclosed is a hair-dyeing method using the said composition. The hair dyed with the composition has an almost natural and fast black color.
