The present disclosure relates a method for the lightening of keratinous fibers, particularly human hair, wherein a lightening agent (AM) containing at least one special dimethylcyclosiloxane and at least one special polydimethylsiloxane is used. Use of the special siloxanes results in improved care of the keratinous fibers with simultaneous improvement of the lightening effect. Furthermore, the present disclosure relates to a corresponding packaging unit (kit-of-parts) and the use of a combination of special siloxanes to improve the care of keratinous fibers while simultaneously improving the lightening effect.

Lightening method using special siloxane compounds

The disclosure relates to an agent for the dyeing of keratinic fibers, in particular human hair, containing in a cosmetic carrier (a) at least one direct-acting dye, (b) at least one amphoteric surfactant, in particular at least one alkyl betaine, and (c) at least one alkyl polyglycoside, in particular at least one alkyl polyglucoside, wherein the weight-related total amount of amphoteric surfactant (b) in the agent, based on the weight of the agent, is less than the weight-related total amount of alkyl polyglycoside (c) or equal to the weight-related total amount of alkyl polyglycoside (c). The disclosure also relates to the use of the agent for the dyeing of keratinic fibers, and to a method in which the agent for the dyeing is applied to the keratinic fibers.

Tinting shampoos

The present disclosure concerns an agent for colouring keratinous fibres, in particular human hair, containing, in a cosmetic support,

Toning shampoo with improved colour performance

Methods for styling, in particular for straightening, keratin fibers, in particular human hair, in which (i) a styling agent comprising carbocisteine and/or a salt thereof is applied to the keratin fibers and left there, (ii) the fibers, after a leave-in time, &#x2014;are not rinsed, &#x2014;are optionally dried, (iii) the fibers are mechanically deformed from exposure to heat, significantly minimize the negative consequences of styling and reduce in particular electrostatic charging and hydrophilization of the hair.

Hair straightening with carbocisteine

The subject matter of the present disclosure is an oxidative dye for oxidative color change of keratinic fibers, in particular human hair which contains, in a cosmetically suitable vehicle, at least one alkalizing agent, at least one oxidative dye precursor of the developer type and at least one oxidative dye precursor of the coupler type, at least one extract of Quassia amara and, based on the weight of the oxidative dye, from about 0 to less than about 0.1 wt % peroxide compounds.
