Swelling is a rare occurrence, affecting approximately 5% of patients who undergo a hair transplant procedure. It typically manifests on the forehead and may extend to the eyelids around day 4 or 5.  Should swelling occur, there is no need to be concerned, as it usually resolves within a period of 2 to 3 days. To alleviate the swelling, you can follow these steps: Take ice cubes or, if unavailable, a wet cloth soaked in cold water. Place the ice cubes or wet cloth on a piece of cloth. Apply the ice pack or wet cloth to the swollen area for 2 to 3 minutes. Repeat this process 4 to 5 times daily for 2 days.
