When using professional products, follow the manufacturers instructions. Best would be to leave this to the professionals, but if you must do it on your own, then here we go...








Developers 10, 20, 30 %26amp; 40 volume are the most common. Each brand recommends it slightly different but a rule of thumb would be,





10 volume is for depositing color


20 volume is for depositing color, covering grey resistant hair, and lifting or lightening color 1-2 levels.


30 volume is for lightening 2-3 levels


40 volume is for lightening 3-4 levels.





CHECK THE MANUFACTURER INFORMATION, this info may vary with the product.





Level- is the lightness or darkness of a hair color
