Abstract: The present invention relates to a cosmetic composition comprising: one or more dicarbonyl derivatives corresponding to formula (I) below, and/or derivatives thereof and/or hydrates thereof and/or salts thereof: in which formula (I) R═H, COOH, linear or branched C1-C6 alkyl which is optionally substituted with an OH or COOH or Br radical; phenyl or benzyl optionally substituted with an OH or COOH radical; or alternatively an indolyl radical or one or more silanes corresponding to formula (II) below and/or oligomers thereof: R1Si(OR2)z(R3)x(OH)y  (II) in which formula (II): R1 is a linear or branched, saturated or unsaturated, cyclic or acyclic C1-C6 hydrocarbon-based chain substituted with a group chosen from the following groups: amine NH2 or NHR (R═C1-C20 and especially C1-C6 alkyl optionally substituted with a radical comprising a silicon atom, C3-C40 cycloalkyl or C6-C30 aromatic), or with a hydroxyl group, a thiol group, an aryl or aryloxy group which is unsubstituted or substituted, in particular with an amino group or with a C1-C4 aminoalkyl group; R1 possibly being interrupted with a heteroatom (O, S or NH) or a carbonyl group (CO), R2 and R3, which may be identical or different, represent a linear or branched alkyl group comprising from 1 to 6 carbon atoms, y denotes an integer ranging from 0 to 3, and z denotes an integer ranging from 0 to 3, and x denotes an integer ranging from 0 to 2, with z+x+y=3. The invention also relates to a process for straightening keratin fibers, especially the hair, using the compounds of formulae (I) and (II) with a straightening step using a straightening iron at a temperature of at least 150° C., preferably ranging from 150 to 250° C.
