Colour advice please

[ninar]

Hi all. My client wants to go from colour on the left to the colour on the right, how would you achieve this please x

I would paint dark shade on the roots, then split hair into 4 sections, working from bottom to top on each quadrant taking 1 " sections pulling the base colour through some sections and foiling out some blonde weaves with conditioner

Same as above. You could maybe do without foil too if you're confident enough
