Microblading can be done over an existing brow tattoo, however the old tattoo must be significantly faded for the hair strokes to show through and look natural. Please advise if you have an existing tattoo and submit a picture to determine if you are a candidate for this procedure. If not a good candidate we will discuss what other options you have. Corrections can be done over the majority of old existing tattoos. Removal maybe needed to get desired results.
