Estimating the term…
The present invention relates to a composition and a method of levelling hair color, especially lighter colored hair or including lightened streaks or bleached streaks or bleached as a whole and after certain period of time contrast—difference in color—between the re-growth and formerly lightened parts is clearly visible. The first objective of the present invention is an aqueous composition for levelling hair color comprising at least one fatty acid salt, preferably an in-situ formed ammonium salt, and one or more non-ionic surfactants at a total concentration between 5 and 30% by weight, calculated to total of the composition, and having a pH between 5 and 12, with the condition that non-ionic surfactant system has an HLB value not exceeding but including 10, calculated from the mol fraction of individual non-ionic surfactants excluding non-ionic silicone surfactants in the non-ionic surfactant mixture and individual HLB values of non-ionic surfactants. Furthermore, use of the composition for levelling hair color and a method of levelling hair color are disclosed.
