Processes to pre-treat hair with organic solvents |
摘要 |
The present invention discloses methods and kit-of-parts for treating keratinous fibres prior to dyeing to control and modulate dye uptake into the fibre. Organic solvents having log P of from -4.0 to -0.5 are used to manufacture pre-treatment composition to be applied to the hair. When the hair is pre-treated with at least one organic solvent having a log P of from -4.0 to -0.5 it reduces the dye uptake. One or more compositions to pre-treat the keratinous fibres can be effortlessly applied on different zones of the hair and can be left in place or removed prior the application of the dyeing composition.
