Looking for some advice about allergic reactions to hair dye.
Dye went on on Wednesday afternoon at hairdressers, was a bit itchy at the time but not too bad, next day (Thurs) was a hit more itchy but again nothing awful. Then woke up yesterday feeling terrible, red swollen ears and red angry raised patches down sides of face and forehead, scalp like it’s burning although it’s not red, nausea, bad guts and lightheaded. Went to A&E on advice from speaking to my GP yesterday morning and was put straight on fairly high dose of oral steroids for 3 days (today is 2nd day of steroids) and antihistamines - felt quite a bit better yesterday arvo, happy days, but then woken up today feeling awful again. Taken steroids and antihistamines again etc..
Now worrying that unless I can get this dye out of hair I am going to be re-introducing the allergy constantly and will run out of steroids after tomorrow.. and then it’s Christmas :-/
Can anyone share experiences? How long did the reaction last and did you have to cut all your hair off?!
