John Warner, a co-founder of the discipline of green chemistry (which uses non-toxic molecules over synthetic chemicals), and a small team of scientists have developed a new and truly revolutionary way to treat gray hair. Hairprint puts the eumelanin protein back into the cuticle of your hair, restoring it to its original color. This product—suitable for those of us with brown or black hair—is the first and only hair coloring product to be certified nontoxic by MadeSafe, a certifying organization with the highest standards in the world. Even better? Hairprint gives 20% of its profits to providing education to girls in the developing world.
