摘要:
The present invention relates to a process for treating keratin fibers, preferably hair, comprising the steps of: (i) applying to the keratin fibers a reducing composition comprising at least one disulfide and at least one thiol, wherein the weight ratio of disulfide/thiol is from 0.35 to 0.75, inclusive, preferably 0.4 to 0.7, and more preferably 0.45 to 0.65; (ii) optionally rinsing the keratin fibers; (iii) oxidizing the keratin fibers; and (iv) optionally rinsing and/or drying the keratin fibers. The present invention provides a new treatment process, in particular a permanent deformation process, for keratin fibers such as hair, which can provide superior cosmetic effects such as long-lasting deformation, sufficient curl efficiency, reduced hair degradation and non-malodor, in a relatively short period of time.

The present disclosure relates to a process for dyeing keratin fibers comprising applying to the keratin fibers a composition comprising at least one hydrophobic direct dye with a logP of greater than 2, in an aqueous-alcoholic dyeing medium comprising less than or equal to 60% water, wherein the dye composition is in contact with the keratin fibers and is exposed to a temperature greater than or equal to 60° C.
摘要:
The present disclosure provides dye compositions comprising at least one hydrophobic direct dye with a logP of greater than 2, at least one organic or mineral acid with a pKa of less than 4.5, in an aqueous-alcoholic dyeing medium comprising at least 60% by weight of water relative to the total weight of the composition, the pH of the composition being less than 7. The compositions allow shades ranging from pastel to strong colorations to be obtained on keratin fibers. Furthermore, the coloration obtained makes it possible to achieve or even exceed the fastness of oxidation dyeing.
