| 摘要 |
The invention relates to a composition comprising i) one or more direct dye(s) comprising a disulphide function or functions or comprising a protected-thiol function or functions, and ii) one or more siliceous compounds comprising a thiol function or functions, used for dyeing keratin fibres, in particular human keratin fibres such as the hair. It also relates to the method of dyeing keratin fibres using said composition and to the use of direct dyes comprising a disulphide or protected-thiol function associated with the siliceous compounds comprising thiol functions, in the dyeing and lightening of keratin fibres. This composition allows new systems for very powerful, homogeneous hair dyeing, which are fast with respect to external agents and which do not impair the cosmetic properties of keratin fibres. |
