MACS lift should have nothing to do with your skull or scalp
Hi there, not sure what happened, but my best guess is that there might have been some kind of pressure placed to cause the hair loss. Stress on your body from a major surgery can also cause some hair loss, which should come back over a period of 3-6 months.
MACS style facelifts can be done with a small amount of sedation and local tumescent injection into the face and neck. It usually only takes 3 hours so unless you had other procedures done at the same time, this is all very unusual.
You may want to try putting some Latisse on the bald spots to stimulate hair growth faster.
Best of luck to you!
Intracranial injections are not possible
but without knowing where your hair loss was, its impossible to comment on possible causes. Hair can often recover so give yourself time and if its not better, your options include hair transplants, excising the bald spots, or doing nothing and covering it with your adjacent hair.
just another reason not to travel internationally for surgery. you have a problem and nobody to see except strangers on the internet. best of luck
