Those who are interested in henna makeup thinking it to be more natural than other types of makeup should think again. Most cosmetics that contain henna, henna oil or extract, also contain artificial dyes and chemicals.
Natural henna is a plant with green leaves that are turned into a green powder. It is then mixed with water to make a paste and applied on skin and hair. It's absolutely natural but there aren't many options in terms of color. Henna always creates a red dye on skin and hair. Depending on how long it is left on, it can range from a light orange color to a very dark red.
Henna makeup, however, comes in many shades, including brown and black. Obviously, there are other dyes used in addition to the henna.
