This is a henna hair dye method which is much better for your hair health in comparison to a box dye (which has a lot of chemicals that open up the hair shaft and thus dries it out)

It has the staying power of a sort of stain and by that I mean, the more you wash your hair, the faster the colour will fade.

As other people commented, it is a very messy dying method as it is a powder consistency that you mix with a liquid that goes everywhere. But it makes up for it in terms of the price, because it is very cheap . It is about +- R15 from any indian grocery shop such as Gorimas etc.
