Will this neutral henna change the color of my dark hair?

On darker hair shades, such as dark brown or black, the visual color change from 100% cassia leaf powder is usually very subtle. The primary effect is not a dramatic shift in hue, but rather an increase in light reflection, which can make hair appear shinier and more polished. The fine plant particles coat the hair shaft, smoothing the cuticle and allowing light to bounce off more evenly. While some users report a faint warm-golden nuance, on deep dark tones this may be barely noticeable under normal lighting. The main benefits for darker hair are often felt as improved texture, softness, and a sense of fullness rather than a visible color transformation. If you are seeking a noticeable color change, this product may not meet that expectation, as it lacks the strong pigments found in traditional red henna or chemical dyes.
