What Does 30 Volume Developer Do?
A 30 volume developer is a type of hair developer that is used to lighten hair by depositing more pigments. It is typically used when a significant color change is required, such as going from dark to light hair. The 30 volume developer can lift the hair up to three levels, providing a more noticeable result than a lower-volume developer. While it is effective at lightening hair, it can also be damaging to hair if used improperly or too frequently, so it is important to follow instructions and use caution when working with this product.
