PROBLEM TO BE SOLVED: To provide a disubstituted benzene derivative and a hair restorer containing these derivatives as an active ingredient. SOLUTION: The general formula: [In the formula, R 1 and R 2 independently represent a C 1-30 hydrocarbon group which may be substituted or 5 or 6 containing 1 to 4 hetero atoms selected from oxygen, sulfur and nitrogen atoms. R 3 represents a hydrogen atom, an optionally substituted alkyl group, an acyl group, An alkoxycarbonyl group, a phenoxycarbonyl group or a carbamoyl group which may be substituted, b, p and q each represent a fixed integer] or a salt thereof, and a hair restorer containing the compound as an active ingredient. |
