Description

(Not mentioned in the original text) Furthermore, the present invention includes the following embodiments. 1. A cosmetic method for dyeing or applying makeup to keratin fibers, particularly eyelashes and/or eyebrows, preferably eyebrows, the method comprising at least a) Cosmetic dyeing composition A comprising one or more natural dyes selected from the group consisting of neoflavonoids, garlic tannins and catechytic tannins, proanthocyanidins and their derivatives, and mixtures thereof, or preferably one or more plant extracts containing them, and advantageously an antioxidant, in a physiologically acceptable medium. b) Applying leveling cosmetic composition B, which contains at least one iron salt and/or aluminum salt, particularly iron gluconate or iron sulfate, to the keratin fibers in a physiologically acceptable medium, Composition A is applied before or after Composition B, preferably before Composition B. Herein, composition A further comprises a substance for promoting and/or increasing the penetration of natural dyes into keratin fibers, particularly eyelashes and/or eyebrows, preferably eyebrows, wherein the substance is selected from bicyclic ethers, fatty acid esters containing polyethoxylated C6-C18 hydrocarbon chains, and mixtures thereof, preferably selected from bicyclic ethers in which each ring of the bicyclic molecule contains a number n of 3- to 10 members, fatty acid esters containing saturated or unsaturated linear or branched C6-C18 hydrocarbon chains (using other C6-C18 hydrocarbon chains) that are polyethoxylated to at least 2, particularly 2-12 degrees of ethoxylation, and mixtures thereof, characterized in that composition A further comprises a substance for promoting and/or increasing the penetration of natural dyes into keratin fibers, particularly eyelashes and/or eyebrows, preferably eyebrows, wherein the substance is selected from bicyclic ethers, fatty acid esters containing polyethoxylated saturated or unsaturated linear or branched C6-C18 hydrocarbon chains (using other C6-C18 hydrocarbon chains), and mixtures thereof. 2. The cosmetic method according to item 1, wherein composition A comprises a substance that promotes and/or increases the penetration of natural dyes into keratin fibers, particularly eyelashes and eyebrows, preferably eyebrows, the substance being selected from dimethyl isosorbide, PEG-7 glyceryl cocoate, and mixtures thereof. 3. The cosmetic method according to item 2, wherein composition A comprises dimethyl isosorbide as a substance that promotes and/or increases the penetration of natural dyes into keratin fibers. 4. The cosmetic method according to any one of claims 1 to 3, wherein an iron salt and/or aluminum salt, preferably iron gluconate or iron sulfate, is added to leveling composition B on an immediate basis before leveling composition B is applied to keratin fibers, particularly eyelashes and/or eyebrows, preferably eyebrows. 5. A cosmetic method according to any one of claims 1 to 4, wherein the dyeing composition A comprises at least one natural dye selected from the group consisting of hematoxylin, hematein, brazylein, brazylin, gallic acid, catechin, castaragin, vescalazine, and/or procyanidins and mixtures thereof, or a plant extract containing them, in particular a plant extract selected from the group consisting of logwood extract, Mexican logwood extract, chestnut extract, natto gall extract, Anogeisus bulk extract, pine extract, tea extract, grapevin extract, sorghum extract, cocoa extract, myrobalan extract, hibiscus extract, strawberry extract and mixtures thereof, preferably a plant extract selected from the group consisting of logwood extract, Mexican logwood extract, chestnut extract and mixtures thereof. 6. The cosmetic method according to any one of claims 1 to 5, wherein natural dyes or plant extracts containing them are present in a total content of 0.1% to 10% by weight, preferably 2% to 5% by weight, relative to the total weight of the composition. 7. The cosmetic method according to any one of claims 1 to 6, wherein the dye composition A further comprises a nonionic surfactant, particularly an alkyl glucoside, preferably a decyl glycoside. 8. The cosmetic method according to any one of claims 1 to 7, wherein the dyeing composition A further comprises a polymeric gelling agent, preferably an acrylic polymeric gelling agent. 9. The cosmetic method according to any one of claims 1 to 8, wherein composition A further comprises at least one additional colorant selected from pigments, dyes and mixtures thereof, in particular at least one additional colorant selected from direct dyes, preferably at least one additional colorant selected from cationic direct dyes. 10. The cosmetic method according to any one of claims 1 to 9, wherein the leveling composition B comprises at least one film-forming polymer. 11. - Apply dyeing composition A to keratin fibers, especially eyelashes and/or eyebrows, preferably eyebrows, for an exposure
