L’oréal Professionnel Metal Detox Pre-Treatment 500 ml

L’oréal Professionnel Metal Detox Pre-Treatment 500 ml. Professional pre-treatment metal neutralizer system. Before professional oxidation colouring, balayage or bleach service. Wash after wash, metal particles -such as copper- accumulate inside the fiber. They can be responsible for breakage and sensitization during colour, balayage and bleach services. Concentrated with Glicoamine 10% and enriched with Ionene, this pre-treatment protects the fiber before any service by neutralizing copper overload. Fiber integrity is preserved.
