4K Black is a toner mask with premium pigments that effectively neutralize unwanted yellowish tones in discolored hair, and restores faded highlighted hair to a fresh and vibrant look.
Formulated with a moist action and high hydration power, this mask strengthens hair strands, reduces breakage, and enhances shine, color definition, and overall luminosity. It also creates an incredible grey effect by correcting unwanted tones.
Each package provides up to 15 applications.
Here are the instructions for use:
- Start by washing your hair with Anti-Residue Shampoo. Repeat if necessary.
- Divide your hair into four quadrants and apply the Toner from root to ends, starting with the darkest sections of your hair.
- Leave it on for 5 to 15 minutes or until you reach your desired color.
- Rinse thoroughly and style your hair as desired.
Important note: Due to the pigments in the product, it is important to seek the assistance of a professional hairdresser to monitor the effect of the product during the processing time. Rinse the product off as soon as you reach the desired effect to avoid over-pigmenting the hair strands.
