Review (2/5): New government approved ingredients are 1/10 as effective as those used in the past
Believe the 1 and 2 star reviews because they are the truth. However it is not the fault of the manufacturer as lead acetate has been removed from all hair dye products so you will find nothing better than this. I am still trying to figure out a way to use this product that will work and not rinse out with hair washing. Again, do not blame the manufacturer, but it would be nice if an ingredient could be found which would work as well as lead acetate without the health risks so we could have a formula that works again.
