Abstract
Provided is a process for dyeing or lightening human keratin fibers, comprising applying to the keratin fibers: a) at least one anhydrous composition (A) comprising at least one fatty substance and at least one surfactant; b) at least one composition (B) comprising monoethanolamine and at least one basic amino acid; and c) at least one composition (C) comprising at least one oxidizing agent; provided that when the process is a dyeing process, the at least one anhydrous composition (A) is free from organic amines and the at least one composition (B) comprises at least one oxidation dye and/or at least one direct dye fiber. Also provided is a multi-compartment device comprising: a first compartment comprising at least one an anhydrous composition (A) comprising at least one fatty substance and at least one surfactant; a second compartment comprising at least composition (B) comprising monoethanolamine and at least one basic amino acid; and a third compartment comprising at least one composition (C) comprising at least one oxidizing agent.
