............. is one of the #1 asked question of going Blonde. The decision for each of your hair should be simple. If there is brass of any sort after using Level 12 with double 40 Volume. Then you should use Cream lightener, If its beautiful after Level 10,11 or 12. Then that should be your choice

hair....one person doesn't...
