Black henna is commonly used to decorate and color nails, but it can cause many potential damages that negatively affect the health of nails. In the following report, we review in Dalili Medical a set of damages associated with the use of black henna on nails and hair, according to our website.
Black henna is made from a mixture of para-phenylenediamine (PPD) with an appropriate amount of natural henna. Although henna has been used for centuries to decorate the body, black henna is considered a modern product in the field of hair and body care. Pure henna is extracted from a plant known as Lawsonia inermis, and it is very gentle on the skin and hair. While the chemical dye PPD is used in many products such as fabrics and fur, and is also used in some photography processes. Natural henna is mixed with these chemicals to better control color shades, but it is listed among the substances that are considered major allergens upon contact.
Black henna contains chemicals such as hair dyes that may cause some skin problems, unlike natural henna, which has an earthy smell and does not contain these harmful substances.
Black henna is one of the options that women resort to to decorate themselves or to draw some decorations on certain parts of the body, as it appears as a temporary tattoo. It can last on the skin for a period ranging from two to three weeks, depending on the condition of the skin and the extent of its exposure to water during that period.
Traditional henna, as mentioned, is orange in color and usually dries slowly. Therefore, the substance paraphenylenediamine (p-Phenylenediamine - PPD) has been added to some types of commercially available henna, with the aim of converting regular henna into black henna. This substance is supposed to help:
- Make the color that henna gives to the skin deeper and more stable.
- Speed up the drying process of henna on the skin.
Most of the potential risks of black henna stem from this substance, which is considered a common allergen in hair dyes. While hair dyes contain specific and safe levels of this substance, black henna often contains high and unsafe levels of it.
There are a set of steps that facilitate the process of preparing black henna at home, including:
. **Preparing henna powder and mixing it with lemon juice** First, the henna powder must be prepared by using a plastic or ceramic container to avoid rust. We empty the henna powder into the container, then add the lemon juice and start stirring the ingredients quickly until they are well mixed. It is preferable to continue stirring until the mixture becomes thicker and takes on the consistency of a consistent paste.
. **Adding a little black food coloring** We add a small amount of black food coloring to darken the henna color to match the hair color. After that, we cover the container with plastic wrap, then press the bottom of the container to make sure all air bubbles are removed.
. **Place the bowl under a heat source for at least 12 hours** The bowl should be placed under a heat lamp for at least 12 hours to ensure that the ingredients react well.
Remove the lamp and temporarily remove the plastic, then add a little sugar and henna oil until the mixture becomes smooth. After that, cover it again and place it under the lamp for an additional 12 hours.
- **The paste should be stirred from time to time** You should stir the paste from time to time to ensure that the mixture is prepared in the best way, so that it becomes similar to yogurt paste. It is also preferable to add half a lemon to the mixture if it is very thick.
