Hi.
Let’s start off stating that if someone doesn’t have about 50/60% of their hair highlighted or balayage then this formula probably will not work. I’m incorporating a photo from her last appointment for you to see how blonde she was before:
This formula is on the lighter side of tones & really needs that lift in the hair to achieve the correct deposit. So, you may have to lighten your client a little! Be sure to use olaplex when doing so!
