Real henna stains the skin a rich red-brown colour.
The colour from natural henna isn't black. The paste you apply may appear dark brown or black before application, especially if essential oils have been added to enhance the staining process. However, the actual stain on the skin will always be within the red-brown spectrum. The shade can vary slightly from a lighter orange-brown to a deeper mahogany, depending on factors like:
- Henna Quality: The freshness and purity of the henna powder.
- Skin Type: Individual skin chemistry affects the final colour.
- Application Time: How long the henna paste remains on the skin.
- Aftercare: How well the area is cared for after paste removal.
Black Henna is Dangerous: It's important to note that so-called "black henna," which produces a very dark, almost black stain, is not natural henna. It typically contains a chemical dye called paraphenylenediamine (PPD), which can cause severe allergic reactions, permanent scarring, and long-term health problems. Authentic henna is never black.
Therefore, when seeking henna tattoos or hair dye, be wary of anything advertised as "black henna." Always prioritize your health and safety by ensuring the product is made from pure, natural henna.
