Abstract

It is provided a granulated hair dye composition, a poultice obtained with it, a method for preparing it and a method for dyeing thereof. The granulated hair dye composition comprises a natural hair dyeing agent, a natural thickening agent, and optionally a direct dye, wherein the natural dyeing agent is coated with the natural thickening agent, thereby forming granules. It is provided a dust-free composition, comprising fewer materials than conventional non-oxidative hair dyeing compositions, and mostly from natural origin, that could be easily mixed with water and applied onto hair as a poultice with limited or no dripping, while providing an improved user's dyeing experience and an even dyeing of hair, without comprising shine and hair feel.
