Description
L'Oréal Professionel Blond Studio Oil Developer 9T 20 Vol 1000ml is a luxurious, oil-enriched oxidant specifically designed for use with the professional Blond Studio Multi-Techniques 9 bleaching powder. This 20 Vol (6%) version provides controlled, powerful, yet protective lift—ideal for techniques that require moderate lift and maximum hair protection.
Thanks to the unique oil-based formula, the hair's lipid content remains optimally balanced , even during intensive lightening treatments. This leaves hair noticeably softer, more supple, and less porous, visibly improving both color processing and the final result. The rich, creamy texture ensures even distribution and effortless application, essential for techniques like highlights, balayage, air-touch, and full-fat lightening.
While the 20 Vol is powerful enough to achieve a strong lift, this version offers a safer, more gentle, controlled lift than the 30 Vol version. Combined with Multi-Techniques 9, the 20 Vol developer can also—depending on hair quality, base color, and technique—achieve a lift of up to 9 tones under optimal conditions, making it a versatile choice for professional blonde services.
