Conventional hair dyes typically work by opening the hair cuticle and using chemical reactions to deposit colour inside the hair shaft. In contrast, this Iranian Henna with Dead Sea Minerals is a plant-based colourant derived from finely milled Lawsonia inermis leaves. The active colouring substance, lawsone, attaches to the keratin on the outer part of the hair rather than penetrating it deeply. This creates a translucent colour layer that sits on the surface, which is why the final shade is heavily influenced by your natural starting hair colour, the duration the paste remains on, and the temperature of the mixture during application.
On lighter hair, this mechanism often yields golden, coppery, or auburn tones, while on darker hair, it imparts warm chestnut reflections and richer depth. Because the pigment coats the hair shaft, it can smooth the surface and help light reflect more evenly, often resulting in a glossier appearance. This approach is frequently chosen by those seeking a warmer, more natural-looking result than many conventional synthetic dyes provide, or for those looking to refresh faded lengths and add warm dimension to natural hair without harsh chemicals.
