This is the question we're asked most in the colour chair, so here's the straight answer.
Grey coverage is permanent colour on the regrowth, covering every grey. It gives an even, solid result and it suits people who want no grey showing at all. The trade-off is maintenance: the line comes back every month or so, and a contrast between dark colour and white regrowth is the most obvious kind there is.
Grey blending works with the grey rather than against it. Fine highlights and lowlights break up the contrast, and a soft gloss over the top takes the yellow out of the grey and ties it to your natural colour. The grey reads as brightness. It grows out softly, so most of our grey blending clients go longer between visits than they did with full coverage. It starts at $150 with a graduate, $180 with a senior and $210 with a director, and takes about two and a half hours.
Moving from years of solid coverage to blending usually takes more than one appointment, because the old colour in your lengths has to be broken up as the new growth comes through. We'll map that out with you at the consultation, with a price for each step.
