What result can I expect on my current hair colour — medium brown, light blonde, or grey hair?

The final shade depends on your starting colour, porosity, and percentage of grey. On lighter or pre-lightened hair (light blonde to light brown), the burgundy pigments show up more saturated and vivid, giving a noticeable red-violet tone. On medium brown hair, the same pigments appear deeper and more muted, adding a subtle wine reflection rather than a strong colour shift. Grey or white strands are highly porous and lack underlying pigment, so they tend to absorb colour more strongly; the burgundy can look brighter and more intense on those areas, which helps blend regrowth but may also create a slight highlight effect. If your hair is very porous, bleached, or heavily grey, the tone develops faster and can end up stronger than expected. A strand test on a hidden section — following the leaflet timing — is the only reliable way to preview the result on your specific hair before committing to a full application.
