How does this henna differ from conventional hair dyes, and what kind of colour result should I expect?

Unlike oxidative dyes that open the hair cuticle and alter the inner pigment, this henna powder coats the outside of each strand with finely milled herbal particles. The colour sits on the surface, so it cannot lighten your hair — it only adds depth or refreshes your existing tone. On untreated hair close to your natural base, the result tends to look richer and more glossy, and the hair often feels fuller and smoother after rinsing. On grey or bleached sections, the plant pigments behave differently: they may appear brighter, more translucent, or uneven because there is no underlying melanin to anchor the shade. Previous chemical colouring, porosity, and even water hardness can shift the final tone. Because the effect is cumulative, repeated applications deepen the colour gradually rather than delivering a dramatic one-step change. If you are used to permanent dyes that promise exact shade matching, treat this as a tonal enhancer rather than a precise colour match.
