No, it is not painful. Before the hair transplant, the head region is completely anesthetized using painless anesthesia devices. After the procedure, if you regularly use the prescribed pain relievers provided by your doctor, you will only experience minor discomfort; moreover, during the hair transplant procedure itself, there is no pain. To prevent swelling after the hair transplant, it is important to drink plenty of water, strictly follow the medication prescribed by your doctor, and above all, refrain from smoking.
