Bicyclic aromatic compound having the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or alkyl, at least two of R.sub.1 -R.sub.4 radicals being other than hydrogen, A represents methylene or dimethylene; when A represents dimethylene, R.sub.1 and R.sub.3 together can form a methylene or dimethylene radical, R.sub.5 and R.sub.6 represent hydrogen, halogen, lower alkyl, lower alkoxy or hydroxy, R' represents hydrogen, hydroxy, alkoxy, C.sub.1 -C.sub.4 cicyloxy or amino, R" represents hydrogen or lower alkoxy, or R' and R" together form an oxo, methano or hydroxyimino radical, B represents cyclohexyl, cyclohexenyl, cyclohexadienyl or phenyl, substituted or not, R represents --CH.sub.2 OH or --COR.sub.7, R.sub.7 represents hydrogen, --OR.sub.8 or ##STR2## R.sub.8 represents hydrogen, C.sub.1 -C.sub.20 alkyl, monohydroxyalkyl, polyhydroxyalkyl, aryl, aralkyl or a sugar residue. r' and r" represent hydrogen, alkyl, monohydroxyalkyl, polyhydroxyalkyl, aryl or benzyl, the residue of an amino acid or an aminated sugar, or taken together form a heterocycle, and the salts of the compound of formula I and their optical isomers as well as the tautomeric forms of the compounds of formula I with the exception of 2-[(5,8-methano-5,6,7,8-tetrahydro-2-naphthyl) carbonyl] benzoic acid. The compounds are useful in the treatment of the hair and skin having an oily appearance.
A bicyclic aromatic compound having the formula ##STR17## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each independently represent hydrogen or lower alkyl, at least two of the R.sub.1 -R.sub.4 radicals being other than hydrogen,
