Balayage Formula Questions
Can the AI tell me which lightener strength to use for balayage?
Yes. ColourKey recommends developer volume based on the existing level, the target lift and whether the hair is porous or previously coloured — not a generic 20 or 30 vol.
Does it handle grown-out balayage (refresh services)?
Yes. The transformation mode compares current vs desired and detects banding, grown-out sections and previous colour history to plan the refresh formula.
What if my client has been box-dyed?
You can flag box dye history in Hair History. ColourKey adjusts the formula and may recommend a strand test or a corrective pre-treatment step.
Which toners work best for balayage finishes?
ColourKey selects from deposit-only glosses (Shades EQ, Color Touch, Dia Richesse, Colorance) for balayage toning — products designed for use over lifted hair without further lift.
