Can hair coloring trigger a facial rash?

Many individuals experience a facial rash a few days after hair coloring. There are a variety of reasons for this and the most common is the hair dye that was used.

The reason why a facial rash occurs after coloring the hair is that the skin is relatively thinner and more reactive than the scalp. The scalp is thick which is why reactions to hair dye rarely trigger rashes.

Additionally, an individual might have utilized a certain hair dye product for several years without any issues until the immune system becomes sensitized to the chemical via an unnoticed scrape, cut or other form of skin damage.

Common cases of a facial rash due to hair coloring

  • Paraphenylenediamine (PPD) – this is a chemical present in hair dye that is likely to trigger allergic reactions. It is found in various permanent hair dye products and considered effective in infiltrating the hair shaft and follicle and even attaching to the skin proteins. These features make it a strong antigen that can trigger allergic reactions.
  • Cobalt – this is also present in some hair dyes which can trigger reactions such as a facial rash after coloring the hair. The chemical provides the pigment in some light and medium brown colors.
  • Glyceryl thioglycolate – this is a chemical present in permanent wave solutions that can be utilized along with hair dye products.
  • Cocamidopronyl betaine – this is a substance derived from coconut which is present in various soaps, shampoos and bath products. This chemical function as a surfactant (formation of bubbles) which is a feature of various soaps that provide a cleaning effect. Since it is also present in various shampoos, it can be overlooked as a cause for the facial rash.
