PURPOSE:To provide a preventive and remedy for gray hair exhibiting extraordinarily excellent preventive and remedying effect, by using vitamin D3 or vitamin D3 derivative as a component. CONSTITUTION:The objective preventive and remedy for gray hair is prepared by compounding preferably 0.001-5wt% one or more compounds selected from vitamin D3 (i.e. cholecalciferol) and its derivative (e.g. 25-hydroxycholecalciferol, 1alpha-hydroxycholecalciferol, dihydrotachysterol, etc.). When vitamin D3 or its derivative is applied to the scalp, it activates the melanocyte which is a melanine-producing cell existing in the hair bulb of the scalp hair root, and exhibits the preventive and remedying effect. |
