Demi-permanent hair color is a type of hair dye that is "deposit only" and does not contain ammonia, so it will not lighten hair. It contains a small amount of peroxide, which allows for subtle color enhancement and increased longevity. Demi-permanent hair color is long-lasting and can last up to 24 to 28 shampoos. The more you shampoo, the quicker the color will fade. It adds richness and depth to natural color, beautifully blends up to 50% gray, and may be used on texturized or relaxed hair. Demi-permanent hair color is great for anyone who wants a temporary color change or for those looking to enhance their current shade with a new tone. It is also recommended for people with less than 25% gray hair, as it only lives on the surface of the hair follicle and outer cuticle, not allowing for any color to really get in there and cover grays all the way.
