    • A composition for inducing and stimulating hair growth and/or reducing hair loss comprises at least one alkylpolyglycoside and at least one compound having formula (I) in a physiologically acceptable medium. ##STR1## In compound (I) , R.sub.1 represents the group ##STR2## where in R.sub.3 and R.sub.4 may be selected from hydrogen, alkyl, alkenyl or cycloalkyl. R.sub.3 and R.sub.4 may also form a heterocycle with the nitrogen atom to which they are bonded. The heterocycle may be an aziridinyl, azetidinyl, pyrrolidinyl, piperidinyl, hexahydroazepinyl, heptamethyleneimine, octamethyleneimine, morpholine or 4-low alkylpiperazidinyl group. These heterocycles may be substituted at the carbon atoms by one to three alkyl, hydroxy or alkoxy groups. R.sub.2 is selected from hydrogen, alkyl, alkenyl, alkylalkoxy, cycloalkyl, aryl, alkylaryl, arylalkyl, alkylarylalkyl, alkoxyarylalkyl and/or haloarylalkyl. The physiologically acceptable acid addition salts of the compound may also be used.
    • 用于诱导和刺激毛发生长和/或减少脱发的组合物包含至少一种烷基多糖苷和至少一种在生理学上可接受的培养基中具有式(I)的化合物。 (I)在化合物(I)中,R 1表示基团,其中R 3和R 4可以选自氢,烷基,链烯基或环烷基。 R3和R4也可以与它们所键合的氮原子形成杂环。 杂环可以是氮丙啶基,氮杂环丁烷基,吡咯烷基,哌啶基,六氢氮杂基,七亚甲基亚胺,八亚甲基亚胺,吗啉或4-低级烷基哌嗪基。 这些杂环可以在碳原子上被一至三个烷基,羟基或烷氧基取代。 R2选自氢,烷基,烯基,烷基烷氧基,环烷基,芳基,烷基芳基,芳基烷基,烷基芳基烷基,烷氧基芳基烷基和/或卤代芳烷基。 也可以使用该化合物的生理上可接受的酸加成盐。
