I make my own henna paste using only 100% natural henna and other natural ingredients, like lemon juice, sugar and essential oils (lavender, cajeput, frankincense). The color achieved from using natural henna is typically a reddish brown color. Within that is a range depending on a few factors like the area and thickness of skin.

(Black henna stain is created by a paste mixed with chemicals that can scar and burn the skin. Avoid black henna!
If the design in the photos look black the paste has been left on.)
