L'Oreal Professionnel Metal Detox Metal Neutralizer Pre-Treatment Spray

What it is:
Metal inside the fiber creates both a risk of breakage and negatively impacts results during color, balayage and lightening services.

What it does:
The Metal Detox Metal Neutralizer pre-treatment traps and neutralizes metals inside the hair fiber before color, balayage or lightening services to reduce breakage and create reliable color results.

What else you need to know:
Liquid texture leave on spray. The Metal Detox Metal Neutralizer Pre-Treatment is unique in that there is no added time to the service. Mist onto the hair and let the formula airdry while prepping formulas. Then, there is no rinsing necessary - apply color or lightener directly afterward for best results.
