I only use natural handmade henna paste.
Henna is a wet paste that needs to dry and stay on the skin for at least 8 hours in order to get a dark stain. Once the paste is applied, you will not be able to move freely neither to cover the skin with clothes. I make the henna paste myself, it contains natural henna powder, distilled water, organic sugar and essential oils. If you have any skin allergy, please let me know in advance.
Natural henna is never black. When someone says they do black henna they are probably using some additives which may be harmful to your skin. Natural henna produces a beautiful orange to dark maroon stain that gives different color on different skins. On palms, the color is darkest, on the back of the hand the color is lighter and on the arms it gets even lighter.
