PURPOSE: Provided is a composition for dyeing human keratin fibers, such as hair, which comprises at least one direct dye or oxidation dye and at least one aminosilicone. CONSTITUTION: A composition for dyeing keratin fibers comprises in a cosmetically acceptable medium, at least one dye chosen from direct dyes and oxidation dyes, and further comprises at least one aminosilicone chosen from formula(1) and (2). In the formula(1), m and n are numbers with a sum (n+m) ranging from 1 to 1000, n is a number ranging from 0 to 999, and m is a number ranging from 1 to 1000; R1, R2 and R3, which may be identical or different, are chosen from a hydroxyl radical and C1-C4 alkoxy radicals, at least one of the radicals R1 to R3 being an alkoxy radical, and in the formula(2), p and q are numbers with a sum (p+q) ranging from 1 to 1000, p is a number ranging from 0 to 999, and q is a number ranging from 1 to 1000; R1 and R2, which are different, are chosen from hydroxyl radicals and C1-C4 alkoxy radicals, at least one of the radicals R1 and R2 being an alkoxy radical.
