Henna is made using the dried, crushed leaves of the henna plant (Lawsonia inermis). The natural dying properties found in henna are tannins of red pigments. Natural henna usually comes as a powder which is activated by hot water whereas henna/metallic salt products can come as a powder or liquid. Either form should be used with a deep conditioner because they can be drying to the scalp and hair.

Henna is more of a temporary "stain" than a dye. Although the color produced by henna usually lasts 30-35 days, the henna itself may take months to completely wear away from the hair shaft. For this reason it's suggested that you wait before following up the use of this product with any sort chemical procedure (i.e. relaxers, chemical dyes, etc).
