The present invention relates to a process for hair treatment for tra - ered a behavior improved and less oxidative hair, especially human hair.It was found that, when the compositions of oxidative treatment commonly used are mixed with other composition consisting of predominantly carboxylic acids.The effects of staining and / or discoloration of the compositions are enhanced, the homogeneous staining / destaining of the hair fibers is obtained and the priedades natural cosmetic hair are maintained.A process comprises applying the hair a composition obtained by mixing the ready to use for the form, comprising one or more alkalizing agents and having a pH of 7.5 to 12.B being an aqueous composition comprising one or more agents oxy before and having a pH of 1.5 5 and C comprising (I) one or more acids carbox u00ed - licos or salts thereof having 3 or more carboxyl groups and (II) one or more acids org u00e2ni cos additional and / or its salts having one or two carboxyl groups.The composition C comprises (I) and (II) at a concentration of 10 to 100% by weight.The ready to use composition has a pH of 8 to 11, comprises (I) and (II) at a concentration of 1 to 10% by weight, and is prepared by mixing a, B and C in a ratio in weight in the FAI - XA 1: 2: 0.2 to 1: 1: 1.A kit for hair comprises the compositions a, B and C.a presente invenção refere-se a um processo de tratamento capilar para tra-tamento melhorado e menos oxidativo do cabelo, especialmente, cabelo humano. descobriu-se que, quando composições de tratamento oxidativas comumente usa-das são misturadas com outra composição compreendendo predominantemente ácidos carboxílicos, os efeitos de coloração e/ou descoloração das composições são aprimorados, coloração/descoloração homogênea de fibras capilares é obtida e pro-priedades cosméticas naturais do cabelo são mantidas. um processo compreende aplicar no cabelo uma composição pronta para uso obtida misturando as composi-ções a, compreendendo um ou mais agentes
