**1. Introduction**

Recently, hair transplantation has been frequently commonly applied for aesthetic surgical procedures. Hair transplantation has a low complication rate according to other aesthetic surgical procedures. However, it can lead to serious complications if proper attention is not given. But there are a wide range of possible complications that are less severe and manageable. Common postoperative complications of hair transplantation are listed in **Table 1**.

### **2. Pain**

Postoperative pain in most of the patients occurs after hair transplantation surgery. This pain occurs especially in hair transplantation performed with FUT (follicular unit transplant). Because due to the transection of peripheral nerves during strip harvesting. In FUE (follicular unit extraction) method, an average of 3000 graft transplantation procedures lasts for 6–8 h. Muscle pain can occur depending on the lying position during this period. Small breaks need to be given during the process, intraoperative analgesic injection and postoperative NSAID (nonsteroidal anti-inflmmatory drugs) use to prevent and reduce pain [1].

#### **3. Edema**

Postoperative edema is the most common complication in hair transplantation. The average incidence of postoperative edema in hair transplantations varies from 40 to 50%. Edema can develop due to tumescent anesthesia and trauma during processing. Tissue edema begins at the time of surgery, but it is only evident 3–5 days later when it descends over the forehead. Occasionally, edematous fluid travels into the periorbital tissues and causes periorbital ecchymosis. Additionally, in some cases, this edema is so severe that patients cannot open his/her eyes.

To prevent and minimize edema, patients should be explained in the lying position during the postoperative period. The use of massage, cold pack, systemic steroids, infiltrative steroids, and NSAID can reduce edema.

#### **4. Asymmetry**

Attentive planning and marking of the recipient site will minimize the risk of asymmetry. Causes of asymmetry include the design of false frontal hairline, density difference between the right and left frequency, and previously deformed head. Always check your design markings in a mirror, viewed from behind the patient's head and at his eye level and get his approval as well. You will frequently be surprised how different it looks in the mirror than when you are standing in front and 2 m away [2].
