A demi-permanent color is a ‘Level 2’ option that lasts much more than semi permanents without harming the strands, even if they are damaged. It lasts for up to 26 shampoos, has less quantity of peroxide to lift the cuticle only a bit, and has no ammonia. Such a color type is a deposit only color because it does alter the natural pigmentation but just adds color, shine, and volume. Thus, it is great for enhancing the prevalent hair color. It is preferable for covering the highlights, refreshing a bit faded look with shine, or changing to a darker shade.
Because the added color mixes with larger pigment molecules, it takes time for the color to fade or wash out. A demi-permanent color blends gray with a natural effect of highlighting and is ideal to cover 25% gray strands. Some of the top brands to consider for such colors are Paul Mitchell, Matrix, Wella Koleston, Schwarzkopf, and Clairol.
