Hair Color Lighting at Home, you should use a suitable peroxide for your hair along with the hair lightening powder. Peroxide is a liquid substance that activates hair-opening powder. Peroxide liquid is available in 10, 20, 30 and 40 volumes. These show how strong the liquid is. You have to choose the degree according to your hair and the color you want to open. We can say that the hair color scale consists of 10 colors. Number 1 corresponds to black color; Number 10 represents the lightest yellow. You have to decide how much hair you need to lighten according to your hair color.
We mentioned that there are different volumes for peroxides.
Volume 10 does not generally affect very dark hair. If you usually have light colored hair or if your hair is naturally light, you can choose volume 10 to lighten a few tones. If your hair is light brown and you want to apply a bit of tone opening, volume 20 will be enough for you. With Volume 20, you can open your hair up to two or three tons.
Volume 30 peroxide will lighten your hair color in three or four shades
However, be careful not to keep peroxide in your hair too much. Otherwise, it may cause sensitization on your scalp. If you have sensitive skin, be careful to apply peroxide so that it does not come into contact with your scalp and hands. If you want to lighten your hair to very light blond, you need to apply the peroxide not in one time, but in two or three different sessions. Be careful not to apply the sessions successively. Volume 40 will allow you to open your hair to the desired level, but the more damage it will cause. Therefore, if you are not professional in hair, it will be healthier not to apply volume 40 peroxide. If you apply it, do not leave it on your hair for more than ten minutes.
