 L’Oréal Professionnel Blond Studio 9 Oil Developer 30 Volume 9% is a professional oil-enriched developer formulated specifically for use with Blond Studio 9 Lightening Powder and Blond Studio 9 Bonder Inside. Its creamy consistency promotes smooth mixing and controlled application while helping boost lightener performance and support softer-feeling hair after lightening.

What It Does

This 30 Volume / 9% developer activates Blond Studio lightening powder for professional off-scalp blonding services. Its mineral-oil-enriched base helps accelerate lift during the early stages of lightening, improve application consistency, and smooth the hair cuticle. L’Oréal specifies the 30-volume version for lengths and ends/off-scalp applications, not direct on-scalp use.

How to Use

For professional use only. Mix exclusively with the compatible Blond Studio 9 lightener according to the service being performed:
