Henna, a natural dye derived from the Lawsonia inermis plant, has been used for centuries to color hair, skin, and fabrics. However, its use can also pose health risks if not applied properly. Health Canada, the country's national health department, has issued guidelines and warnings regarding the safe use of henna. Here are 10 henna tips from Health Canada experts to ensure safe and effective use.
Understanding Henna and Its Risks
Before applying henna, it is essential to understand its composition and potential risks. Natural henna is generally considered safe, but black henna, which contains paraphenylenediamine (PPD), can cause severe skin reactions, including burns, blisters, and scarring. Health Canada warns against the use of black henna, especially on children, as it can lead to long-term health consequences.
Safe Application and Precautions
To ensure safe application, follow these guidelines: - Always perform a patch test before applying henna to a larger area. - Use natural henna products that are free from PPD and other harsh chemicals. - Avoid applying henna to broken skin or open wounds. - Wear protective gloves when applying henna to prevent skin staining. - Keep henna away from children and pets to avoid accidental ingestion or application.
