Kerosene is sometimes used as an additive in henna mixtures to achieve a darker and faster stain on the skin. However, the use of kerosene in henna is highly discouraged and considered harmful for several reasons:

1. Skin Irritation and Allergic Reactions: Kerosene is a petroleum-based product that can cause skin irritation, redness, itching, and allergic reactions when applied to the skin. It can disrupt the skin’s natural barrier, leading to dryness, inflammation, and potential long-term damage.

2. Chemical Sensitization: Prolonged exposure to kerosene in henna mixtures can sensitize the skin, making it more susceptible to adverse reactions in the future. This means that even after the initial use, individuals may develop allergies or severe reactions to other substances in the future.

3. Toxicity: Kerosene is a toxic substance that can be absorbed through the skin and pose significant health risks. It contains various harmful chemicals, including hydrocarbons, which can be harmful when absorbed into the bloodstream. Inhalation of kerosene fumes can also lead to respiratory issues and other health problems.

4. Fire Hazard: Kerosene is highly flammable, and its use in henna mixtures increases the risk of accidental fires during application or drying. Applying kerosene-based henna near an open flame, candles, or other heat sources can be extremely dangerous.

5. Legal and Regulatory Issues: The use of kerosene in henna products may violate local regulations and laws related to cosmetic safety and labeling requirements. In many countries, the use of kerosene or other harmful substances in cosmetics is strictly prohibited.

It’s crucial to prioritize the use of natural and safe ingredients in henna mixtures. Natural henna, made from the leaves of the Lawsonia inermis plant, produces a beautiful reddish-brown stain without the need for harmful additives. When purchasing or getting henna applied, always ensure that the henna is made from pure, natural ingredients and does not contain kerosene or other potentially harmful substances.

If you suspect that you have been exposed to kerosene-based henna or are experiencing adverse reactions, it is recommended to seek medical attention immediately and inform the healthcare professional about the specific product used.
