What Is PPD?
Paraphenylenediamine (PPD) is a chemical that is used in hair dye to create permanent colour. It is a strong, dark-coloured dye that is able to penetrate the hair shaft and bind to the natural pigment, melanin. This gives the hair its colour. PPD is also used in some other products, such as henna tattoos and permanent markers.
PPD was first used in hair dye in the early 1900s. It was quickly adopted by the hair dye industry because it was a very effective way to create permanent colour. PPD is also relatively inexpensive, which made it a cost-effective choice for hair dye manufacturers.
PPD was used in hair dye for many years because it was a very effective way to create permanent colour. However, in recent years, there has been growing concern about the safety of PPD. Some studies have shown that PPD can cause allergic reactions, including contact dermatitis, eczema, and hives. In some cases, PPD reactions can be severe and even life-threatening.
As a result of these concerns, many hair dye manufacturers have begun to reformulate their products to remove PPD. In 2012, the European Union banned the use of PPD in hair dye. The United States has not yet banned the use of PPD, but many manufacturers have voluntarily removed it from their products.
If you are considering using hair dye, it is important to check the label to see if it contains PPD. If you have a history of allergies, it is best to avoid hair dyes that contain PPD. There are many other hair dyes available that do not contain PPD, so you should be able to find one that meets your needs.
