The present invention relates to a process for treating human keratin fibers and/or the skin from which the said fibers emerge, in order to induce and/or stimulate the growth of the human keratin fibers and/or to stop their loss and/or to increase their density, comprising at least the application, to the human keratin fibers and/or the skin, of a cosmetic composition comprising an effective amount of at least one piperidine derivative of general formula (I),
in which:
R
1
denotes a halogen or a radical chosen from a linear or branched C
1
-C
6
alkyl radical, a group OR, a group NRR′, a CF
3
group, a group NHCOR or a group CONRR′;
R
2
denotes a linear or branched C
1
-C
20
alkyl or alkenyl radical, the hydrocarbon-based chain of which may be optionally interrupted with a —CO— function optionally substituted with at least one group OR, COOR, NRR′, NHCOR or CONRR′ and/or with a phenyl group optionally substituted with one or more radicals R
1
;
with R and R′ denoting, independently of each other, a hydrogen atom or a linear or branched C
1
-C
6
alkyl radical,
m represents an integer ranging from 0 to 5; and n represents an integer ranging from 0 to 5. or a salt or isomer thereof, leaving the said composition in contact with the keratin fibers and/or the skin from which the fibers emerge, and optionally rinsing the keratin fibers and/or the skin.
本发明涉及一种处理人类角蛋白纤维和/或这些纤维生长的皮肤的方法,以诱导和/或刺激人类角蛋白纤维的生长和/或阻止它们的脱落和/或增加它们的密度,包括至少将含有至少一种一般式(I)的哌啶衍生物的有效量的化妆品组合物施用于人类角蛋白纤维和/或皮肤,其中:
R1表示卤素或从线性或支链的C1-C6烷基基团、OR基团、NRR′基团、CF3基团、NHCOR基团或CONRR′基团中选择的基团;
R2表示线性或支链的C1-C20烷基或烯基基团,其碳氢基链可以选配地被具有至少一个OR、COOR、NRR′、NHCOR或CONRR′基团和/或一个苯基(该苯基可以选择地被一个或多个基团R1取代)的—CO—功能中断,其中R和R′独立地表示氢原子或线性或支链的C1-C6烷基基团,m表示一个范围从0到5的整数;n表示一个范围从0到5的整数,或者其盐或异构体,将该组合物留在与角蛋白纤维和/或这些纤维生长的皮肤接触,然后选择性地冲洗角蛋白纤维和/或皮肤。
