L'oreal Professionnel Spray for the restoration of dyed hair Metal Detox Pre-Treatment Spray 400ml

Spray for the restoration of colored hair Loreal Professionnel Metal Detox Pre-Treatment Spray

Metal that can build up inside the fiber can create a risk of breakage and adversely affect staining results during dyeing, sizing, and bleaching. Excess copper within the hair fiber can interfere with the oxidant. This means that the oxidant can do its job properly. Enriched with glycoamine, this patented technology helps neutralize excess copper, meaning it won't affect your color.

Because the formula penetrates the fiber, the result is smooth, lasts longer, and the hair becomes brightly shiny.

Mode of application

• Spray onto dry hair in sequence from tips to roots.
• For short hair: Apply 8 to 10 pumps.
• Medium-long hair: 15 to 20 pumps
• Focus on the length, as this is where the hair is most porous, so there will most likely be more metal deposits.
