How Grecian works. Different hair colors are the result of different amounts of melanin, nature's coloring protein. Darker hair simply has more melanin than lighter hair. As melanin production decreases with age, hair turns gray. Grecian has the unique ability to replace lost melanin with a similar-acting pigment. You can regain just the right amount of lost color by applying Grecian for fewer or more days. Grecian works for any hair color. Hair looks thicker, healthier. Grecian contains a hair-thickening ingredient that works by expanding the hair's diameter. Plus, it actually repairs and strengthens hair, reducing hair loss from breakage. The result: healthier, thicker-looking hair. Made in U.S.A.
