The invention claimed is: 1. A hair treatment composition comprising: (a) at least one non-neutralized anionic surfactant chosen from fatty carboxylic acids, fatty ether carboxylic acids, N-acylamino acids, or mixtures thereof, wherein the fatty carboxylic acids are represented by formula (I): RCOOH (I), in which R is a linear and saturated hydrocarbon radical containing from 6 to 40 carbon atoms; (b) at least one non-ionic surfactant chosen from monooxyalkylenated, polyoxyalkylenated, monoglycerolated, polyglycerolated nonionic surfactants, or mixtures thereof, wherein the at least one non-ionic surfactant comprises at least one non-ionic surfactant comprising 10 to 100 oxyalkylene units; (c) at least one fatty alcohol corresponding to structure R—OH, wherein R is chosen from saturated and unsaturated, linear and branched radicals containing from 8 to 40 carbon atoms; (d) an alkaline-component comprising ammonia and/or a salt thereof, and optionally at least one additional alkaline agent, and (e) at least one hair dyeing agent or hair permanent waving agent, wherein the hair treatment composition comprises less than about 2% by weight of a phosphoric surfactant, relative to the total weight of the hair treatment composition, and wherein the hair treatment composition is formed from (i) a first composition in the form of an emulsion comprising water and oil phases, further comprising (a) at least one non-neutralized anionic surfactant, (b) at least one non-ionic surfactant and (c) at least one fatty alcohol, (ii) a second composition comprising (d) an alkaline component comprising ammonia and/or a salt thereof, and optionally (iii) at least one additional composition, wherein the first composition has a pH below a pKa of at least one non-neutralized anionic surfactant and does not comprise a neutralizing agent in an amount sufficient to neutralize the anionic surfactant(s), wherein one or more of the first, second, or optional additional compositions comprise (e) at least one hair dyeing agent or hair permanent waving agent, wherein the first composition is free of ammonia and is free of salts of ammonia, and wherein the hair treatment composition comprises a total amount of ammonia and/or salts thereof ranging from 0.1% to 20% by weight, relative to the total weight of the hair treatment. 2. The hair treatment composition according to claim 1 wherein the at least one non-neutralized anionic surfactant is present in an amount ranging from about 0.01% to about 20% by weight, relative to the total weight of the hair treatment composition. 3. The hair treatment composition according to claim 1 wherein the at least one non-ionic surfactant is present in an amount ranging from about 0.1% to about 20% by weight, relative to the total weight of the hair treatment composition. 4. The hair treatment composition according to claim 1 wherein the at least one fatty alcohol is chosen from lauryl alcohol, cetyl alcohol, stearyl alcohol, oleyl alcohol, behenyl alcohol, linoleyl alcohol, undecylenyl alcohol, palmitoleyl alcohol, arachidonyl alcohol, erucyl alcohol, cetearyl alcohol, or mixtures thereof. 5. The hair treatment composition according to claim 1 wherein the at least one fatty alcohol is present in an amount ranging from about 0.1% to about 40% by weight, relative to the total weight of the hair treatment composition. 6. The hair treatment composition according to claim 1 , wherein the total amount of the alkaline component ranges from about 0.1% to about 20% by weight, relative to the total weight of the hair treatment composition. 7. The composition according to claim 1 wherein the viscosity of the hair treatment composition is at least 3 Pa·s at 25° C. 8. The hair treatment composition according to claim 1 wherein the at least one hair dyeing agent or hair permanent waving agent is chosen from oxidation dyes, direct dyes, or reducing agents. 9. A method for treating hair, comprising applying to the hair a hair treatment composition comprising: (a) at least one non-neutralized anionic surfactant chosen from fatty carboxylic acids, fatty ether carboxylic acids, N-acylamino acids, or mixtures thereof, wherein the fatty carboxylic acids are represented by formula (I): RCOOH (I), in which R is a linear and saturated hydrocarbon radical containing from 6 to 40 carbon atoms; (b) at least one non-ionic surfactant chosen from monooxyalkylenated, polyoxyalkylenated, monoglycerolated, polyglycerolated nonionic surfactants, or mixtures thereof, wherein the at least one non-ionic surfactant comprises at least one non-ionic surfactant comprising 10 to 100 oxyalkylene units; (c) at least one fatty alcohol corresponding to structure R—OH, wherein R is chosen from saturated and unsaturated, linear and branched radicals containing from 8 to 40 carbon atoms; (d) an alkaline component comprising ammonia and/or a salt thereof, and optionally at least one additional alkaline agent; and (e) at least one hair dyeing agent or hair permanent waving agent, wherein the hair treatment composition comprises less than about 2% by weight of a phosphoric surfactant, relative to the total weight of the hair treatment composition, and wherein the hair treatment composition is formed from (i) a first composition in the form of an emulsion comprising water and oil phases, further comprising (a) at least one non-neutralized anionic surfactant, (b) at least one non-ionic surfactant and (c) at least one fatty alcohol, (ii) a second composition comprising (d) an alkaline component comprising ammonia and/or a salt thereof, and optionally (iii) at least one additional composition, wherein the first composition has a pH below a pKa of at least one non-neutralized anionic surfactant and does not comprise a neutralizing agent in an amount sufficient to neutralize the anionic surfactant(s), wherein one or more of the first, second, or optional additional compositions comprise (e) at least one hair dyeing agent or hair permanent waving agent, wherein the first composition is free of ammonia and is free of salts of ammonia, and wherein the hair treatment composition comprises a total amount of ammonia and/or salts thereof ranging from 0.1% to 20% by weight, relative to the total weight of the hair treatment composition. 10. The method according to claim 9 , furthering comprising applying a mechanical tension to the hair before applying the composition. 11. The hair treatment composition according to claim 1 , wherein the pH of the hair treatment composition ranges from 9 to 12. 12. The hair treatment composition according to claim 1 , wherein the first composition further comprises at least one non-ionic surfactant. 13.
