L´Oreal Professionnel Serie Expert Metal Detox Pre-treatment 500ml

The 500ml professional bottle of L’Oréal Professionnel Serie Expert Metal Detox Pre-Treatment removes accumulated mineral deposits and trace metal particles before you begin any coloring or chemical service. Leftover metals from hard water, previous dye cycles, or environmental exposure interfere with oxidative formulas, causing uneven lift, muted tones, or accelerated fading. This targeted pre-cleanse neutralizes those hidden contaminants so your chosen pigment develops uniformly.

Apply directly to damp hair before mixing your standard color or lightening product. Work the solution through each section, process according to established salon guidelines, then rinse completely and proceed with your intended formula. This preliminary step blocks unwanted metal-catalyzed reactions, balances strand porosity, and allows demi-permanent, permanent, and bleaching agents to deposit exactly as calculated.

Constructed for continuous salon use, the concentrated 500ml container supports demanding appointment volumes while preserving batch stability. Stylists handling color corrections, global transformations, or routine touch-ups rely on this detox step to eliminate variables. The result is consistent tone delivery, sharper root-to-end coverage, and extended wear between appointments.
