Swelling occurs because, during the hair transplant procedure, we inject normal saline into the scalp to raise the scalp just a little above to save the underlying structures(nerves, arteries, and veins). It’s the same normal saline that gravitates down and settles around the eyes and forehead. It’s a harmless fluid and gets absorbed into the blood within 48 hours. So, there is no need to take the medicine that can reduce the swelling, it’ll subside on its own within 1 or 2 days. If you wear dark glasses, you can hide your swelling easily and can carry on with your work. If you want to avoid swelling at all costs, then you can opt for anti-swelling belts offered by Recover Hair Transplant.
