Abstract
The invention relates to a dye composition comprising a thiol/disulfide fluorescent dye comprising amino groups, and to a dyeing process which has a lightening effect on keratin materials, in particular keratin fibers, especially human keratin fibers such as the hair, using said composition. It similarly relates to novel thiol/disulfide fluorescent dyes and to uses thereof in lightening keratin materials. This composition makes it possible to obtain a particularly resistant and visible lightening effect on dark keratin fibers.
