PURPOSE:To obtain a hair cosmetic which contains, as an active ingredient, alpha-melanocyte-stimulating hormone (alpha-MSH), thus being effective for blackening white hairs, for preventing hairs from whitening by aging with extremely high safety. CONSTITUTION:The cosmetic contains, as an active ingredient, 0.00001-0.01wt.% of alpha-MSH, namely a polypeptide of the formula. The hormone promotes the activation and propagation of chromogenic cells in the hair matrix to increase the tyrosinase activity, and accelerates the transfer of melanin granules from the dendrites of chromoblasts to the cortical cells of hairs to develop its blackening effect. |
