摘要

The invention relates to a composition for caring for or making up the hair or the eyelashes, which is intended to limit their loss and/or to increase their density, and containing a pyrazole compound of formula (I), or a salt thereof: in which: R1 and R2 represent H; an optionally substituted C1-C20 alkyl; or at least one ring optionally containing at least one hetero atom, these rings possibly being fused, comprising a carbonyl or thiocarbonyl function, and possibly being substituted; R3 and R5 represent H, a halogen, OR6, SR6, NR6R'6, CN, CF3, COR6, CSR6, COOR6, COSR6, CSOR6, CSSR6, NR6COR'6, NR6CSR'6, OCOR6, SCOR6, CSNR6R'6, SO2R6, SO2NR6R'6, NR6SO2R'6, NR6C(=NR'6)NR''6R'''6, SiR6R'6R''6, A or at least one ring optionally containing at least one hetero atom, these rings possibly being fused, comprising a carbonyl or thiocarbonyl function and possibly being substituted; R4 represents H, A, COR6, CSR6, COOR6, CONR6R'6, CSNR6R'6, SO2R6, SO2NR6R'6 or at least one ring optionally containing a hetero atom, these rings possibly being fused, comprising a carbonyl or thiocarbonyl function, and possibly being substituted; R6, R'6, R''6 and R'''6 represent H; an optionally substituted C1-C20 alkyl; at least one ring optionally containing at
