This herbal hair dye is versatile and can be personalised by mixing plant powders. For example, if your goal is to achieve deeper brown or near-black tones, henna is traditionally combined with basma (indigo). This combination allows for a wider range of natural shades beyond the warm copper and auburn tones that henna alone typically produces. However, because botanical colourants build differently from synthetic dyes, the final result depends on your unique hair characteristics.
It is wise to perform a strand-test first to see how your specific hair reacts to the lawsone and mineral salts. This is particularly important if you have very light, bleached, damaged, or chemically processed hair, as these conditions can lead to stronger or less predictable colour absorption. Additionally, if you have a sensitive scalp, a patch test in advance is recommended to ensure compatibility with the plant pigments and mineral salts. Consult a specialist before use if you have chronic skin conditions or are pregnant or breastfeeding.
