Will 20 Volume Developer Lighten Hair?: Fast-Track Guide to Understanding Hair Developers

Yes, 20 volume developer can lighten hair, but its effect depends on several factors such as your natural hair color, hair condition, and the product you mix it with. 20 volume developer contains 6% hydrogen peroxide, which is strong enough to open the hair cuticle and allow lightening or color change—but on its own, it only lifts hair by one to two levels. Typically, it's used with permanent hair color or bleach to activate the lightening process. For subtle highlights or to prepare hair for a color change, 20 volume is a common choice. However, those seeking a dramatic lift (e.g., going from dark brown to light blonde) might need a higher volume developer, like 30 or 40. It's best to assess your hair's needs and consult a professional if you're unsure.
