Abstract

The invention herein encompasses the use of aminosilicones to enhance the colour perception of artificially coloured hair. Also encompassed are compositions, a method of use, a kit-of-parts and an article of manufacture.

While consumers are satisfied with the range of options offered by these different shades of color, there remains an overall need for more intense colors in a long-lasting manner. [0003] Without undertaking extensive research to identify new dye molecules, the present inventors have discovered that application of aminosilicones to the hair after the hair has been artificially dyed can provide artificially dyed hair with a permanently enhanced color perception. [0004] The use of aminosilicones is well known in the art - see eg EP 1 31 2342 and EP 1 312 350 . But it has never been rep...
