Identifying pure henna and chemical henna is quite tricky. One should keep following things in consideration while opting for natural henna:
Identify the colour: Real henna stain starts out orange and oxidizes to a reddish brown. However chemical dyes give instant dark colour as it consist of various chemicals in it.
Ingredients: Natural henna paste contains only henna powder, a liquid (water, lemon juice, etc) and an essential oil (lavender, cajuput, tee tree etc). chemicals dye are prepared by adulterating the natural henna paste by adding industrial dyes and solvents gasoline, kerosene, lighter fluid, paint thinner, benzene, and PPD - thereby creating "chemical henna".
Time Durability: Natural henna has no preservatives therefore it is less shelf stable," meaning they expire quickly, and cannot be left out on a shelf for over one week without losing their ability to stain the skin whereas commercial dyes come with preservatives and chemicals that enhance their durability to use.
Smell: Real henna has pleasing and earthy smell, often of essential oils. Chemical henna will smell pungent like chemicals and have unpleasant odor.
Stain duration: Real henna needs to be left on the skin for longer hour’s i.e up to 4 hours in order to stain the skin effectively, and then water should be avoided for 24 hours. It takes about 48 hours to darken. Chemical "henna" is often called "instant henna" because it only needs to be on the skin for 30 minutes or less, you can wash it off with water and the stain is dark immediately.
Side effects: People prone to allergy should use herbal henna as it is same from chemicals like ppd. Chemical henna can cause some side effects such as inflammation of the skin (dermatitis) including redness, itching, burning, swelling, scaling, broken skin, blisters, and scarring of the skin.
