Abstract
The disclosure relates to a cosmetic composition for treating keratin fibres, such as hair, comprising, in a cosmetically acceptable medium: (i) at least one oxidizing agent; and (ii) at least one aminosilicone. The disclosure further relates to the composition's uses, such as dyeing, bleaching, and permanently reshaping keratin fibres. The disclosure also relates to the processes and devices for bleaching, dyeing or permanently reshaping human keratin fibres using the composition.
