I’m allergic to hair dye although I’ve been having my eyebrows waxed for 20 + years. Yesterday I went for an eyebrow wax to someone new and I’ve had a reaction. My eyebrows are swollen and itchy, I know this is about to get a lot worse if she has put dye on them. There was something on them afterwards but I didn’t think it was dye I just thought maybe she put some powder on them. What should I do?
