Will this henna cover grey hair, and how should I prepare for the first application?

Yes, this single-herb botanical dye is effective for covering grey hair, though the result differs from chemical alternatives. Instead of masking greys with a solid, uniform block of color, henna adds warm red, ginger, or mahogany reflections that blend with your natural pigment. This creates a more natural-looking dimension, especially if you have a mix of grey and pigmented hair. However, because the color develops based on your hair's existing tone and porosity, results can vary significantly between individuals.

Before full application, it is strongly advised to perform both a patch test for skin sensitivity and a strand test on a small, hidden section of hair. This is crucial, especially if your hair has been previously chemically treated, bleached, or colored with metallic salts, as these can interact unpredictably with plant pigments. The strand test will give you a reliable preview of the final shade on your specific hair texture. Keep in mind that plant dyes develop gradually; the color will continue to deepen over the next two days, so avoid judging the final result immediately after rinsing.
