Claim:
A method for cosmetically/therapeutically treating an adverse condition/affliction of a keratinous substrate/material to improve the apperance thereof, comprising topically applying onto such keratinous substrate/material, an appearance-enhancing effective amount of at least one 7-oxo-DHEA compound having the structural formula (I): in which R is an alkylcarbonyl radical wherein the alkyl is a C 1 -C 24 alkyl moiety which is saturated or unsaturated, linear or branched, or cyclic and is subsituted with —COOR′ and/or —NR′R′; wherein R′ is a hydrogen atom or a saturated or unsaturated, linear or branched, or cyclic C 1 -C 12 alkyl radical, the alkyl radical optionally containing one or more hetero atoms and optionally being functionalized with one or more of the groups —OR″, —COOR″, halogen, —NR″R″, or with an aryl group, the aryl group optionally being functionalized with one or more of the groups —OR″, —COOR″, halogen or —NR″R″; and R″ is a hydrogen atom or a saturated or unsaturated, linear or branched or cyclic alkyl radical; with the proviso that, in each of the groups —NR′R′ and —NR″R″, the substituents R′ and R″, respectively, are identical or different; wherein the adverse condition/afflication of a keratinous substrate/material is hyperseborrhea and/or imperfections associated thereto, and/or dandruff and/or natural hair loss and/or baldness.
