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. These compositions are effective for coloring or toning hair. The color imparted to the hair is long-lasting (tenacious), neutralizing, and gentle. Methods for making the composition and methods for coloring hair are also disclosed.

Compositions and methods for coloring hair

The disclosure relates to buffer systems having ammonium hydroxide, ammonium bicarbonate, and optionally monoethanolamine, hair color bases, hair color altering compositions, and kits and methods for altering the color of hair. Hair color bases and hair color altering compositions comprise a buffer system having ammonium hydroxide, ammonium bicarbonate, and optionally monoethanolamine.
