Will volume 10 or volume 20 peroxide make hair color lighter?

Volume 10 peroxide is generally used for deposit-only color, while volume 20 peroxide can lighten hair by one to two shades. If you're looking to significantly lighten your hair color, volume 20 is more effective than volume 10. However, the degree of lightening also depends on the hair's starting color and condition. Always consider a strand test to see how your hair reacts.
