I just spoke to a lady who had eyelash transplants 18 months ago. She wanted to know my opinion on her complications, which include: loss of native eyelashes, failure of the transplanted eyelashes to grow, and some infection.
This is the problem I am hearing from many people who have had this procedure and therefore I urge most people to avoid doing this surgery.
