What is all over her? FAQs "What is Henna?" Very simply put: Henna is a temporary all natural tattoo medium. "How does it work?” Paste is applied to your skin and left for several hours when you remove the dried paste you are left with a stain much like leaving a tea bag on a table cloth. The stain darkens over the next 24-48 hours and lasts anywhere from a week to a month, maybe even more depending on how well you care for the tattoo. "Does it hurt?" NO!!! I am the biggest baby in the world. I practically faint and the sight of a needle. Trust me, if there was any pain involved I would be the first person to run away. Henna actually feels WONDERFUL on your skin. It is medicinal as well as decorative. "Does it come in black?" "Does it come in any other color?" The absolute most important thing to know about Henna!!! Real All Natural Henna is NEVER any color but reddish. Palms and feet do stain darker than the forearms, chest and so forth. Commonly if Henna is colored it is because the mix contains additives. Those additives can be anything from tar to ammonia. A VERY popular additive is called PPD. It can be found in black hair dye. Lots of people on vacation get "Black Henna Tattoos" A good percentage of those people end up with horrible allergic reactions. Some people end up with PPD allergies so bad they cannot wear black colored clothes anymore most end up permanently scarred. Please avoid Black Henna.
