Abstract
The present invention relates to the field of lightening keratin fibres and more particularly to the field of lightening the hair. The present invention relates to a process for lightening keratin fibres, in particular human keratin fibres such as the hair, which consists in using on the said fibres i) a substrate comprising on its surface one or more chemical oxidizing agents preferably in solid form, and ii) an aqueous composition preferably comprising one or more chemical oxidizing agents. The present invention also relates to a process for preparing the said substrate thus pretreated.
Claims14
A process for lightening keratin fibers, the process comprising:
- i) applying to the keratin fibers a substrate comprising on a surface at least one first solid chemical oxidizing agent, the at least one first solid chemical oxidizing agent being deposited onto the surface of the substrate by printing, and
- ii) applying to the keratin fibers an aqueous composition comprising at least one second chemical oxidizing agent and at least one alkaline agent;
- wherein the substrate is applied first to the keratin fibers, and then the aqueous composition is applied to the keratin fibers;
- or
- the aqueous composition is applied first to the keratin fibers, and then the substrate is applied to the keratin fibers.
