Some of the most common complications of FUE include swelling, bruising, itching and pain. There is also the risk of bleeding/oozing as well as numbness of the scalp. One noteworthy risk to mention is “shock loss” which is a post-surgical loss of hair that can be greatly diminished if patients resume/start prescription medication given by the hair transplant surgeon and continue it for a period of 6 months after their surgery. You can find more information about this topic in general at hair transplant complications.
