L'oreal Professional Blond Studio 9 Oil Developer

Blond Studio 9 Oil Developer is a premium hair lightening solution designed to enhance the performance of Blond Studio 9 Lightening Powder. Available in both 20-volume and 30-volume options, this oil-enriched developer ensures a smooth application while effectively lifting hair up to nine levels. Its creamy consistency not only facilitates optimal mixing but also helps to protect and smooth the hair cuticle during the lightening process. The 20-Volume Oil Developer is specifically formulated for on-scalp application, making it ideal for achieving uniform results from roots to ends. In contrast, the 30-Volume variant is recommended for use on lengths and ends only, providing versatility for various hair lightening techniques. Both options are designed to work exclusively with Blond Studio 9 Lightening Powder, ensuring the best possible results for your hair. Please note that the packaging of the product may differ from the images displayed on our site due to a recent redesign.
