If your natural hair colour is between light blonde and dark blonde, you can lighten your hair by up to 2 shades using 7.0 Kolora Natural blonde, 7.65 Kolora Almond blonde, 8.0 Kolora Golden blonde, and 9.8 Kolora Ash blonde, or by up to 3 shades using 10.2 Kolora Pearl blonde.
Do not wash your hair the day you intend to do the colouring. Experts recommend that you wait 24 to 48 hours after washing the hair before applying hair dye. Freshly washed hair is devoid of fat, which helps to facilitate absorption of hair dye.
