Abstract
The disclosure relates to the dyeing of keratin materials using styryl hydroxy(cyclo)alkylamino thiol/disulfide fluorescent dyes. Disclosed herein is a dye composition comprising a styryl hydroxy(cyclo)alkylamino thiol/disulfide fluorescent dye and a dyeing process with, for example, a lightening effect on keratin materials such as hair, using said composition. Disclosed herein are novel thiol/disulfide fluorescent dyes and the uses thereof in lightening keratin materials. This composition makes it possible to obtain a lightening effect which can be resistant and visible on dark keratin fibers.
