Abstract: The present disclosure relates to hair coloring base compositions and ready-to-use hair coloring compositions comprising 2-methoxymethyl-P-phenylenediamine, an oxidative dye precursor. The hair coloring base composition is mixed with a developer composition to form a ready-to-use hair coloring composition having a lower than typical pH, 7. These compositions are effective for coloring hair, especially beard hair. The color imparted to the hair is long-lasting (tenacious) and skin sensitivity due to the coloring process is minimized or prevented. Methods for making the composition and methods for coloring hair, especially beard hair, are also disclosed.
