This type of dye is popular in forms such as hair color brushes or sprays, and works to create a layer of color on the surface of the hair that changes the color of the hair. Semi-permanent dye: The drug penetrates the hair shaft but acts more gently on the hair because it does not contain ammonia or ethanolamine. Usually fades away after about 10-15 washes or sooner. Permanent dyeing: The type commonly used, due to its longer service life. Just dyeing to replenish the newly grown hair roots saves more time, lightens the black hair color and covers even faded hair.
