The agent for coloring keratin fibers is free of chemical oxidants, is in the form of an aqueous or aqueous-alcoholic dye-containing preparation, and contains a combination of oxidation dyes and at least three direct dyes. The agent is characterized by a quantitative ratio of oxidation dyes to direct dyes equal to 5:1 to 0.5:1. A method of dyeing hair is described in which the agent is applied to hair and allowed to act on the hair for an acting time of 5 to 60 minutes without addition of chemical oxidants, so that air oxidation provides a uniform and stable coloration of the hair.

A method of conditioning and oxidatively dyeing human hair includes applying an oxidative hair dyeing composition to the human hair in order to dye the human hair and, simultaneously or subsequently to the applying of the oxidative hair dyeing composition, applying a particular hair conditioning composition to the hair. This hair conditioning composition has a pH value of from 3.4 to 3.9, which corresponds to an isoelectric point of the human hair, and contains from 0.001 to 2.5% by weight of a cationic polymer, an optional pH buffer and preferably additional conditioning ingredients, such as a cationic surfactant and/or a fatty alcohol.

The composition for removing or lightening hair color is in the form of a hair color lightening suspension and is mixed with an aqueous oxidizing composition immediately prior to use. The composition includes a combination of from 0.1 to 80 percent by weight of one or more organic lipophilic compounds, namely vegetable or animal fats, vegetable or animal oils, vegetable or animal waxes, paraffin hydrocarbons, higher alcohols or ethers, aliphatic and aromatic esters and/or silicone oils; from 0.1 to 40 percent by weight of at least one lipophilic inorganic or organic thickener, which forms an oleogel and/or lipogel with the lipophilic compounds; from 0.1 to 40 percent by weight of one or more hydrophilic inorganic or organic thickeners; from 10 to 65 percent by weight of at least one inorganic persalt; from 10 to 45 percent by weight of at least one alkaline reacting salt; and auxiliary substances and cosmetic additive ingredients, as needed.
