I had my eyebrows microbladed 5 weeks ago and you can't tell it was done. (photos)

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.
