Black Henna
Black henna is a term often used to describe hair dye that can achieve a deep black color. However, it's important to distinguish between natural black henna, which uses a combination of henna (Lawsonia inermis) and indigo (Indigofera tinctoria), and products labeled as "black henna" that may contain harmful chemicals like para-phenylenediamine (PPD). Here’s a comprehensive guide on both types:
Manufacturing Process of Black Henna
- Vibrant Color: Achieves a deep, intense black color.
- Quick Application: Faster processing time compared to natural methods.
Safety and Precautions
- Allergic Reactions: PPD can cause severe allergic reactions, including itching, redness, swelling, and blistering. Always perform a patch test before use.
- Skin and Hair Damage: Prolonged or frequent use of PPD can damage the skin and hair, leading to dryness, breakage, and chemical burns.
- Regulation: Many countries have regulations limiting the amount of PPD in cosmetic products due to its potential hazards.
