Abstract: The present invention relates to a composition comprising: at least one dicarbonyl compound of formula (I) below and/or derivatives thereof and/or hydrates thereof and/or the corresponding salts: in which formula (I): R represents an atom or group chosen from i) hydrogen, ii) carboxyl —C(O)OH, iii) optionally substituted linear or branched C1-C6, alkyl, iv) optionally substituted phenyl, v) optionally substituted benzyl, vi) an indolyl radical, and vii) an imidazolylmethyl radical, and tautomers thereof, at least one cellulose-based polymer and at least one amphoteric surfactant, the composition having a pH of less than or equal to 4. The invention also relates to a process for straightening keratin fibers such as the hair, which comprises the application to the hair of the composition of the invention, followed by a straightening step using a straightening iron at a temperature of at least 150° C., preferably between 150 and 250° C.

Abstract: The present invention relates to a hair treatment process comprising the application to the hair of an aqueous-alcoholic composition comprising at least 5% of at least one C1-C7 alcohol and at least one organic monoacid, followed by a straightening/relaxing step using a straightening iron at a temperature of at least 100° C. The process of the invention allows good straightening of the hair, while durably reducing the volume and the frizziness effect of the hair.
