Hairdressers have reported that customers are experiencing new allergic reactions to hair dye after contracting Covid, as scientists investigate how the virus could be reprogramming our immune systems.
The BBC reported that the reactions, including rashes and burns, have been recorded by salons in parts of the UK.
One customer said she suffered a reaction to a patch test after having Covid, despite using the same hair dye for ten years. She explained that she developed a “hot burning sensation” behind her ears that worsened “to the point where it had taken layers of skin” off.
