Balay Powder will not impact lift or deposit. No developer adjustment is needed. Any issues with processing time or lift can be solved by using less Balay Powder. As some lighteners provide 9+ levels of lift and others only 4, everything may be adjusted based on personal preference.
Yes! Why carry another set of developers and lightener meant for balayage, when you can just add Balay Powder to your regular lightener? Save money and cut down on the space needed in your professional inventory.
