hi I am allergy to PPD. I  coloured my hair with hennaplus permanent no PPD in it. But the same symptoms occured as if i used a normal hair colour. Much worse i woke up the next day with my neck swollen. Do you think i am allergic to something else?Thanks Joanne
Hello, Welcome to Chat Doctor, and thanks for your query. It is very likely that you are allergic to one or more components of the hair dye. You may require to take antihistamine and to avoid further use of the dye. Take care
