What result can I expect on grey or white hairs?

On grey or white hair, the toning shampoo typically deposits colour more intensely because those strands lack natural melanin and are often more porous. The product description notes that on grey or lightened hair the shade "may appear stronger and more intense" compared to medium or light brown bases. This can be useful for camouflaging first greys around the hairline, but it also means the contrast between pigmented and non-pigmented areas may shift — grey hairs can turn a noticeably deeper tone than the surrounding brown hair.

If you have a high percentage of grey, do a strand test first: apply the shampoo to a small hidden section, follow the timing instructions, rinse, and evaluate. That preview lets you judge whether the depth on grey hairs matches your expectation. For a more even blend across mixed grey and brown hair, some users alternate this toning shampoo with a regular shampoo to build the tone gradually rather than in a single application.
