L'Oréal Professionnel Blond Studio 9 Oil Developer 20 Volume is a professional-grade oxidant formulated exclusively for use with the Blond Studio 9 lightening powder. This oil-enriched developer features a creamy, low-volatility texture that ensures smooth application and optimal mixing while helping to protect hair integrity during the lightening process.

  • Professional Formula: Designed specifically for salon use with Blond Studio 9 powder.
  • Oil-Enriched Texture: Creamy consistency reduces volatility and improves cosmeticity.
  • Controlled Lift: 20 volume (6%) strength suitable for on-scalp applications.
  • Large Format: 1000 ml bottle for high-volume professional use.

The unique oil-based formula helps boost lightening performance and smooths the hair cuticle, resulting in improved post-shampoo softness. It is engineered to work synergistically with Blond Studio 9 powders to achieve clean, luminous blonde results with up to 9 levels of lift depending on the technique used.

This developer is intended for multi-technique lightening applications, including global lightening, highlights, and freehand techniques. The 20 volume concentration allows for safe on-scalp application when following manufacturer guidelines, with a maximum development time of 50 minutes. Do not use external heat during processing.

For best results, mix with Blond Studio 9 lightening powder according to the recommended ratios for your specific technique: 1+1 for global application, 1+2 for enclosed techniques, and 1+3 for open or freehand methods. Always perform a strand test prior to full application.

How to use

Start with clean, dry hair. Section it for even application. Read the instructions carefully. Dispense the desired amount of L'Oreal Professionnel Blond Studio 9 Hair Lightening Oil. Apply evenly from roots to tips using an applicator bottle, brush, or gloves. Comb through for uniform distribution. Check the recommended processing time. Monitor the color change. Rinse thoroughly once you achieve the desired lightness. Condition if needed with a matching or regular conditioner.
