Magnet Ultimate Oil Developer is a hair colour lifting system designed for salon use, delivering precise lightening and protecting hair fibres for healthier, more predictable results. It blends hydrogen peroxide with mineral oil for lightening that feels softer on the strand and it’s reliable in busy colouring appointments. The BondIN System gives a 360º shield for hair during lift, which is saying something when precision matters. Great for busy salons.
Available Sizes & Variants:
900ml oil developer - large salon bottle for daily studio use
Benefits & Features:
- Consistent lift with a creamy, easy spread.
- Precision control reduces overprocessing in tough lift sections, while the BondIN System shields the hair fibre during chemical action, helping you achieve even results with less breakage.
- Stable, creamy texture stays uniform from root to tip, skincare friendly.
- Designed for daily salon use, it's a reliable choice for beauty supply stores.
- Intended for professional colour services, it supports accurate lift across a range of hair types while preserving shine and fibre integrity.
Revlon Professional's Magnet line blends salon heritage with protective performance. This oil developer sits at the heart of the system, using BondIN to form a 360º shield around the fibre and help preserve strength during lift. Hydrogen peroxide powers the lightening action while mineral oil keeps moisture balanced, and PEG-40 castor oil helps create a smooth, creamy texture for precise coverage. In Magnet Blondes contexts, results stay predictable and vibrant, which is why professional beauty supply stores rely on this approach.
