In this procedure, the surgeon removes part of the scalp in the form of a thin strip and then sutures the scalp.

At Hair transplantation by SUT methodRemoval of about 3,000 hair follicles takes 6 to 8 hours. Depending on the patient’s sitting position and position during this time period, muscle pain may occur.

Swelling after hair transplantation

Edema and swelling are the most common complaints and complications in patients after hair transplantation. About 40 to 50% of patients develop this complication after surgery. Edema is caused by injections of anesthetics and trauma and injury during surgery.

Tissue edema begins immediately after surgery, and can be detected 3 to 5 days later, when it affects the forehead.

In rare cases, bleeding may occur after surgery and after leaving the clinic. Putting and applying sterile gauze for about 15 minutes is very good in stopping and reducing the risk of bleeding. In preoperative examinations and tests, patients should be evaluated for coagulopathy and diseases that increase the risk of bleeding, including aspirin, nonsteroidal anti-inflammatory drugs, vitamin E, alcohol, anabolic steroids, and other anticoagulants.

To reduce the risk of bleeding, topical minoxidil, and smoking and other tobacco products should be discontinued at least 2 weeks before surgery. Bleeding during surgery is rare and can be easily controlled with epinephrine injections.

Folliculitis can occur in both the transplant site and the follicle donor area. Folliculitis is treated with antibiotic ointment and warm compresses for 15 minutes, 3 times a day.

This lesion may occur months or even years after hair transplantation. People who have a history of colloid, or who are at higher risk for developing it based on family history, age, and race, should be aware of the potential risk of developing colloid before surgery.


Infection from hair transplant surgery is very rare due to the very arteries of the scalp. Serious infections occur in less than one percent of patients and are most often associated with poor hygiene. Many things play a role in preventing infection, such as a clean operating environment, the use of sterile equipment and methods, and the use of appropriate antibiotics shortly before surgery to prevent possible infections.


Sometimes, very nervous and anxious patients suffer from syncope and fainting during surgery, however, simple measures, such as holding the patient’s foot, often solve the problem.


Transplant necrosis is a rare but very dangerous complication following hair transplantation. This complication occurs during surgery due to damage to the graft arteries. Factors to predict the likelihood of developing this complication include: Patient-related factors: Smoking: Atrophic skin lesions, Diabetes mellitus, scarring at the transplant site, or a history of previous surgery in that area.
