How does this henna colour differ from regular oxidative hair dye?

Regular oxidative dyes use peroxide to lift natural pigment and PPD-based molecules to deposit new colour deep inside the hair shaft. This product works differently: it contains lawsone from Lawsonia inermis (henna) plus other botanical powders that shift the tone toward a neutral light brown. The plant pigments wrap around and bind to the keratin on the outer hair shaft rather than penetrating and lightening from within. Because there is no peroxide, it cannot lighten your hair — it only adds tone on top of what is already there. The final shade depends on your starting colour, grey percentage, porosity, and any previous chemical colouring. It also leaves hair feeling denser and smoother due to tannins and other plant compounds in the finely milled powders.

No PPD or peroxide is present, but a patch test is still recommended because natural ingredients can trigger sensitivity. If you have had a black henna tattoo in the past, your risk of reaction may be higher.
