FIELD: medicine, cosmetology.

SUBSTANCE: cosmetic composition contains complex of active agents (A) having active agent (A1), which is selected from sericine and/or sericine hydrolysates and/or their derivatives and/or their mixtures, and active agent (A2), which is selected from fibroin and/or its hydrolysates and/or its derivatives and/or its mixtures, note that the ratio of active agents (A1):(A2) ranges from 10:90 to 70:30. Two-component agent for colouring keratic fibers consists of the first component (K1) containing at least one preproduct of colour (FV), and the second component (K2) containing at least one complex of active agents (A) consisting of active agent (A1), which is selected from sericine and/or sericine hydrolysates and/or their derivatives and/or their mixtures, and active agent (A2), which is selected from fibroin and/or its hydrolysates and/or its derivatives and/or its mixtures, note that the ratio of active agents (A1):(A2) ranges from 10:90 to 70:30 and at least one of the components contains at least one amphiprotic polymer (AP). Three-component agent for colouring of keratic fibers contains additional third component (K3) containing at least one oxidising component. Method of colouring of keratic fibers comprises applying one of the components over fibers, thereafter, it is kept for the time of reaction and washed out. One of the agents is used for cleaning and/or treating of skin and hair or for restructuring of keratic fibers, precisely human hair. Method of skin and hair treating comprises applying one of the agents to skin or hair, note that it is washed our after the time of reaction from 1 to 45 minutes.

EFFECT: increase of efficacy for the cosmetic agents.
