The invention relates to a process for straightening keratin fibres, comprising: (i) a step in which a straightening composition containing at least two denaturing agents is applied to the keratin fibres, (ii) a step in which the temperature of the keratin fibres is raised, using a heating means, to a temperature of between 110 and 250&#xb0; C.

Process for straightening keratin fibres with a heating means and denaturing agents

The invention relates to a process for relaxing keratin fibers by applying to the keratin fibers a relaxing composition containing at least one denaturing agent with a molecular mass of greater than 18.1 g/mol, present in a molar concentration of between 1M and 8M, and raising the temperature of the keratin fibers to a temperature of between 110 and 250&#xb0; C.
