Progesterone and testosterone are natural softdrugs, but to be used as drugs, their fast and facile metabolism must be prevented and their delivery controlled. A prodrug-soft drug combination can serve this purpose. Thiazolidines of testosterone, testosterone 17-propionate and progesterone were synthesized from the reaction of cysteine alkyl esters, N-methylaminoethanethiol, and mercaptamine and their

The hair shaping composition for permanent shaping of hair contains a cysteine ester of the formula (I): HS--CH.sub.2 --CH(NH.sub.2)--COO--CH.sub.2 --CH.sub.2 --R (I) as a keratin-reducing material, wherein R is a hydroxy group, alkoxy groups, a poly(alkoxy) group or a hydroxypoly(alkoxy) group, or one of its acid additional salts. Cysteine ester compounds and their methods of preparation are also described. Preferred embodiments of the hair shaping composition have a pH of from 4.5 to 9.0 and contain from 4 to 30% by weight of the cysteine ester or its acid addition salt and provide a safe and uniform shaping of hair without allergic or sensitizing reactions.
