Blackcurrant dye could make hair coloring safer, more sustainable

Whether they’re trying to hide some gray or embrace a new or quirky color, people adore hair dyes. But some of these dyes may be harmful to humans and the environment. Now scientists report that they have developed a natural, non-toxic hair dye derived from blackcurrant skins that is as durable as conventional dyes and capable of sustaining hair color through multiple washings.
