  • Patent number: 12005136
    Abstract: The group of inventions relates to the field of hairdressing and includes a method for the translucent dyeing of hair which is carried out by the step-by-step layered application of requisite compositions onto a strip of hair with mechanical action and constant monitoring of the process, said method comprising preparation of the hair for dyeing and dyeing with a dye which has been diluted with an oxidizing agent, wherein preparation for dyeing is carried out using compositions in the form of diffusions which are a mixture of components in which shampoo is used as an active substance, and dyeing is carried out using diffusions which are a mixture of components comprising an oxidative dye and a low-concentration oxidizing agent. The invention also relates to diffusions for implementing the method.

  • Patent number: 5316551
    Abstract: In a method for oxidatively dyeing hair, a pretreatment which comprises contacting hair with an aqueous solution of an effective amount of particular metal/chelate complexes followed by treatment with oxidative dye mixtures is disclosed. The process serves to conform the oxidative dyeing rate of virgin hair to that of the normally noncongruent rate of nonvirgin hair, so as to enhance the efficiency of the oxidative dyeing process, without reducing the intensity or variety of color available.
