Artas FUE hair transplant, unsuccessful (Photo)

Of course you did.  Thats because most practices using an Artas have no clue what they are doing, they have the Artas run by assistants and not the doctor, they end up damaging the donor zone, damaging the grafts, and then patients realize what a mistake they made.I would recommend you get multiple opinions from experienced surgeons in your area. Returning to the same surgeon who gave you unfavorable results prior may not be the wisest decision. 
Multiple opinions will allow you to hear various solutions to the problems in your specific case. Before making any decisions about which type of surgery to go forward with for your second hair transplant, please read up on robotic hair transplants and the risks associated with them. Overall, we see lower graft survival and increased risk of scarring in robotic transplants. Therefore, I always recommend hair transplants done by hand. Feel free to read more about the pros and cons of different surgeries on my site.

Thanks for sharing and very unfortunate to hear that the procedure did not meet your expectations.  It would be a great idea to meet with your surgeon and ask for an opportunity to redo the procedure at a discounted price.
