Why does Eclectic last longer than most competitive demi-permanent systems?

How long does FRAMCOLOR Eclectic demi-permanent, ammonia-free, dye last so long?

FRAMCOLOR Eclectic guarantees the best results in terms of color penetration due to the Capsulate Complex Technology.  The Capsulate Complex forms a conditioning shield around the hair that encapsulates the color and protects it from environmental factors that lead to fadage.
