Blond Studio 9 Oil 20-Volume developer is enriched with oil to enhance the overall performance of the 9-level lightener.

The oil is responsible for the increased volume and predictability of the lightening result. It's our way of achieving up to 9 levels of lightening faster with lower-volume developers. The oxidizer's oily base also enables optimal mixing and application.
