Also know, when should you use a higher volume developer?With hair dye low volume developer is enough to lift the hair cuticle just enough for pigment to slip inside, but when bleaching your hair you’ll need a higher volume developer. This is because you need to open the cuticle enough to allow for the natural color pigment to be removed from your hair.One may also ask, should I use 30 or 40 developer? The majority of hair color formulas work with a volume developer at level 10, 20, 30 or 40. Choose a 30 volume developer when you want a developer that is stronger for a lighter and deeper color. The 40 volume developer is the strongest and has the potential to produce significant changes. Similarly, can you use hydrogen peroxide instead of developer? Short answer, you don’t. Not with the hydrogen peroxide you get from the store, at least. The peroxide is the developer, so you should be using something else with it, and only professional hair peroxide. The peroxide you get from the store, the kind you’d use on a cut, is too strong for use on your hair.Will 40 volume peroxide lighten hair?40 volume is occasionally used to lighten very dark, stubborn hair as part of the bleaching process. It lightens quickly and its effects are harsher than lower concentrations. 40 volume is not recommended for on-the-scalp use. Using 40 volume developer can cause hair damage and chemical burns if not used correctly.
