Microblading + Allergic Q&A

I would like to get microblading/phibrows done, however, I recently had an allergy test and found out I am allergic to nickel. I had microblading about three years ago and I dont believe I had an allergic reaction. Is it ok to get microblading if I have a nickel allergy?

Am I more at risk for allergic reaction to microblading dye (iron oxide) for eyebrows If I have had an allergic reaction to hair color in the past?

Hi, I had microblading done last year November and 2 days ago I went for the removal using Rejuvi. I am having very swollen eyes but no pain or itchiness. I am very worried it will leave scaring. Can you please advise on what I can do? What should I apply? I am just cleaning it with water, does it look like an allergic reaction? The lady who did it told me to apply Vaseline and to put ice pack but it doesnt seem to be helping. Please advise. Thank you.

I had microblading done on 12/19/16 and five weeks later, you can only see about 5 strokes. My photo below shows my results right after the procedure was finished. My eyebrows are still red/pink. Could the problem be allergy to the dye, maybe a nickel (allergy) filled blade, or did the technician not go deep enough? I'm at a loss.

I have even had to use an EPI Pen.

I am allergic to eyebrow tint and hair dyes will this mean I am most likely going to be allergic to microblading?
