I have some grey hairs. Will this dye cover them effectively?

As a permanent cream hair color, this product is designed for long-lasting coverage, including for visible regrowth. It is mentioned as fitting for those covering first grey strands. The creamy texture helps spread the mixture evenly, which improves the chances of thorough saturation on resistant greys. For best results on greying hair, ensure you apply the color mixture thoroughly from roots to ends and follow the recommended development time precisely. Coverage can vary depending on the percentage and coarseness of your grey hair, as well as its porosity. If you have a significant amount of very resistant, wiry grey hair, you might need to leave the product on for the maximum recommended time (always check the instructions leaflet in the kit) and ensure full, saturated application. Performing an allergy alert test 48 hours before use is crucial, especially if you are coloring greys for the first time.
