<p>Coloring hair comprises applying a composition comprising an aminopyrazolopyridine oxidation base including cationic or non-cationic aminopyrazolopyridine oxidation base (I) or (II) on hair. The coloring process is carried out in absence of coupler. Coloring hair comprises applying a composition comprising an aminopyrazolopyridine oxidation base (Q) including cationic or non-cationic aminopyrazolopyridine oxidation base of formula (I) or (II) on hair. The coloring process is carried out in absence of coupler.
