The present disclosure relates to reducing compositions comprising, in an aqueous medium, at least one compound for reducing keratin, ammonia, and at least one mesomorphic phase present in an amount of at least 10% by weight, relative to the weight of the composition. The mesomorphic phase generally comprises nonionic surfactants with an HLB value of less than or equal to 10. The present disclosure also relates to the process for preparing the compositions, and to a process for permanently reshaping or straightening the hair using the reducing compositions, as well as multi-compartment kits for permanently reshaping or straightening the hair, wherein at least one compartment contains the reducing composition.

The present disclosure relates to oxidation dye compositions comprising, in an aqueous medium suitable for dyeing, at least one oxidation dye, ammonia, and at least one mesomorphic phase present in an amount greater than or equal to 10% by weight, relative to the weight of the composition. The present disclosure also relates to the process for preparing the compositions, as well as ready-to-use compositions for oxidation dyeing of keratin fibers, and multi-compartment kits for oxidation dyeing of keratin fibers, wherein at least one compartment contains the dye composition. Another aspect of the present disclosure is an oxidizing composition comprising a mesomorphic phase.
