The method of dyeing hair comprises applying to the hair a dye containing a 2,6-dinitro-aniline derivative having the general formula (I) ##STR1## wherein R represents H, C.sub.1 -C.sub.4 alkyl, C.sub.2 -C.sub.4 monohydroxy alkyl or C.sub.3 -C.sub.4 -dihydroxy alkyl and X represents one of the radicals C.sub.1 -C.sub.4 alkyl, C.sub.2 -C.sub.4 monohydroxy alkyl, C.sub.1 -C.sub.4 perfluoro alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.2 -C.sub.4 monohydroxy alkoxy, C.sub.3 -C.sub.4 dihydroxy alkoxy or halogen. The present invention also comprises hair dyes containing at least one compound having the formula (I) and novel 2,6-dinitro-aniline derivatives. The dyes having the formula (I) have good physiological properties and provide all the yellow shades required for dyeing from a bluish-tinged lemon-yellow via a pure yellow to red-orange.
