Blond Studio 9 Developer harnesses a unique mineral-oil system to stabilise peroxide molecules, reducing volatility and delivering a noticeably softer, more cosmetic feel both after shampooing and when fully dry. Ideal for darker bases seeking high-lift blonding, it activates lifting agents in the early stages for accelerated, predictable lift while optimally neutralising unwanted brassy undertones. Formulated exclusively to work with Blond Studio 9 powder and its built-in 9 Levels Bonder technology, this professional-grade lotion preserves hair integrity and manageability throughout the service.
