A high lift color is a permanent one but has distinct composition to work a bit differently to other dyes. Such colors contain more pigment and ammonia along with a double ratio of a developer of 40 volume due to which it lightens the hair more effectually than the other dyes of blonde and yet tones while lightening.
High lift colors have restricted use although they were introduced to replace bleaches. However, they are not interchangeable with bleach. A high lift color is only for use on virgin hair that is already in light brown shade or a dark blonde color, and that you need 3-7 levels of lift. Matrix and Wella Koleston are some reliable brands for high lift colors.
