What is claimed is: 1. A multistage method for dyeing keratinous fibers, comprising: a) treating said fibers, in at least two stages, with: i) at least one entity chosen from ortho-diphenol and derivatives thereof, ii) at least one metal salt, iii) hydrogen peroxide or at least one system which gen
What is claimed is: 1. A multistage method for dyeing keratinous fibers, comprising: a) treating said fibers, in at least two stages, with: i) at least one entity chosen from ortho-diphenol and derivatives thereof, ii) at least one metal salt, iii) hydrogen peroxide or at least one system which generates hydrogen peroxide, and iv) at least one (bi)carbonate; and b) at least one of mechanically wiping or drying the fibers, wherein the mechanical wiping or drying occurs between the first and last of the at least two treating stages, with the proviso that said method does not comprise a rinsing stage just before the stage of treating the fibers with the at least one (bi)carbonate. 2. The dyeing method of claim 1, wherein the at least one entity is chosen from natural ortho-diphenol derivatives. 3. The dyeing method of claim 1, in which the at least one entity is an ortho-diphenol or derivative thereof comprising an aromatic ring chosen from benzene, naphthalene, tetrahydronaphthalene, indane, indene, anthracene, phenanthrene, isoindole, indoline, isoindoline, benzofuran, dihydrobenzofuran, chromane, isochromane, chromene, isochromene, quinoline, tetrahydroquinoline and isoquinoline, said aromatic ring comprising at least two hydroxyl groups carried by two contiguous adjacent atoms of the aromatic ring. 4. The dyeing method of claim 1, in which the at least one entity is chosen from entities of formula (I), oligomers thereof, and salified forms thereof: in which formula (I): R1 to R4, which are identical or different, represent substituents chosen from: a hydrogen atom, a halogen atom, a hydroxyl radical, a carboxyl radical, an alkyl carboxylate or alkoxycarbonyl radical, an optionally substituted amino radical, an optionally substituted linear or branched alkyl radical, an optionally substituted linear or branched alkenyl radical, an optionally substituted cycloalkyl radical, an alkoxy radical, an alkoxyalkyl radical, an alkoxyaryl radical, it being possible for the aryl group to be optionally substituted, an aryl radical, a substituted aryl radical, a saturated or unsaturated heterocyclic radical which does or does not carry a cationic or anionic charge, which is optionally substituted and/or which is optionally fused with an aromatic ring, said aromatic ring being optionally substituted, and a radical comprising at least one silicon atom; except that, two of the adjacent substituents R1-R2, R2-R3 or R3-R4 can jointly form a saturated or unsaturated, aromatic or nonaromatic and substituted or unsubstituted ring optionally comprising at least one heteroatom and optionally fused with at least one saturated or unsaturated and optionally substituted ring optionally comprising at least one heteroatom. 5. The dyeing method of claim 4, in which the at least one entity is chosen from: flavonols, anthocyanidins, anthocyanins or anthocyans, orthohydroxybenzoates, flavones, hydroxystilbenes, 3,4-dihydroxyphenylalanine or a derivative thereof, 2,3-dihydroxyphenylalanine or a derivative thereof, 4,5-dihydroxyphenylalanine or a derivative thereof, dihydroxycinnamates, orthopolyhydroxycoumarins, orthopolyhydroxyisocoumarins, orthopolyhydroxycoumarones, orthopolyhydroxyisocoumarones, orthopolyhydroxychalcones, orthopolyhydroxychromones, orthopolyhydroxyquinones, orthohydroxyxanthones, 1,2-dihydroxybenzene or a derivative thereof, 1,2,4-trihydroxybenzene or a derivative thereof, 1,2,3-trihydroxybenzene or a derivative thereof, 2,4,5-trihydroxytoluene or a derivative thereof, proanthocyanidins, proanthocyanins, tannic acid, and ellagic acid. 6. The dyeing method of claim 2, wherein the at least one natural ortho-diphenol derivative is chosen from natural ortho-diphenol derivatives present in at least one extract of animals, bacteria, fungi, algae and plants. 7. The dyeing method of claim 6, wherein the at least one extract of an animal, bacterium, fungus, alga or plant is chosen from: extracts of tea leaves, extracts of rosemary leaves, extracts of mate leaves, extracts of fruits, extracts of cocoa beans and/or pods, extracts of vegetables, and extracts of tree wood. 8. The dyeing method of claim 7, wherein the at least one extract is chosen from: extracts of grape, extracts of onion skins, extracts of salad, extracts of dyer's mulberry, and extracts of acacia. 9. The dyeing method of claim 1, in which the at least one metal salt is chosen from manganese and zinc oxides. 10. The dyeing method of claim 1, in which the at least one metal salt is chosen from manganese halides, sulfates, phosphates, nitrates, perchlorates, and salts of carboxylic acids, and zinc halides, sulfates, phosphates, nitrates perchlorates, and salts of carboxylic acids. 11. The dyeing method of claim 1, in which the hydrogen peroxide or at least one system which generates hydrogen peroxide is chosen from hydrogen peroxide and urea hydrogen peroxide. 12. The dyeing method of claim 1, in which the at least one (bi)carbonate is chosen from alkali metal (bi)carbonates and alkaline earth metal (bi)carbonates. 13. The dyeing method of claim 1, wherein the method consists of: a) in a first stage, treating said fibers with one to three compositions collectively comprising: i) the at least one entity chosen from ortho-diphenol and derivatives thereof, ii) the at least one metal salt, and iii) the hydrogen peroxide or at least one system which generates hydrogen peroxide, b) in a second stage, performing at least one of mechanically wiping said fibers and drying said fibers, and c) in a third stage, treating said fibers with iv) at least one (bi)carbonate. 14. The dyeing method of claim 1, wherein the method consists of: a) in a first step, treating said fibers with, together or separately: i) the at least one entity chosen from ortho-diphenol and derivatives thereof, and ii) the at least one metal salt, b) in a second stage, performing at least one of mechanically wiping said fibers or drying said fibers, and c) in a third stage, treating said fibers with, together or separately iii) the hydrogen peroxide or the at least one system which generates hydrogen peroxide and iv) at least one (bi)carbonate. 15. The dyeing method of claim 1, wherein stage b) of the method comprises drying the keratinous fibers using heat. 16. A multistage method for dyeing keratinous fibers, comprising: a) treating said fibers, in at least two stages, with: i) at least one entity chosen from ortho-diphenol and derivatives thereof, ii) at least one metal salt, iii) hydrogen peroxide or at least one system which generates hydrogen peroxide, and iv) at least one (bi)carbonate; and b) mechanically wiping the keratinous fibers to remove excess material, at least once between the first and last of the at least two treating stages, said mechanical wiping occurring either after treating the fibers with ingredients i) and ii) and said excess material comprising ingredients i) and ii), or after treating the fibers with ingredients i), ii), and iii), and said excess material comprising ingredients i), ii), and iii), with the proviso that said method does not comprise a rinsing stage just before the stage of treating the fibers with the at least one (bi)carbonate. 17. The dyeing method of claim 16, wherein stage b) of the method further comprises drying the keratinous fibers using heat.
