Description
This classic developer features a more economical formula comparing to other brands.
Recommended mixing ratios for use on scalp and in foil with VIART UltraBlond 9+ Powder are 1:4 with 3–6% developers (a buffering reaction may occur with higher percentages if metals are present in the hair).
To clean “dirty” blonde the ratios of 1:8 to 1:10 with 9% and 12% developers can be used. Make a test strand before any bleaching service.
