The U.S. Food and Drug Administration (FDA) has enacted a final rule to repeal color additive approval for the use of lead acetate in hair dyes.

Specifically, the final rule amending the color additive regulations to no longer provide for the use of lead acetate in cosmetics intended for coloring hair on the scalp. New data that was available since lead acetate was permanently listed demonstrated that there is no longer a reasonable certainty of no harm from the use of this color additive.

This rule was effective on December 3, 2018.
