FUE (Follicular Unit Extraction): How Does It Work?Facial Plastic Surgery
Various factors such as genetics, malnutrition, stress, and certain health conditions can result in baldness or thin hair. Today, various methods of hair transplant surgery have been developed, which eliminate baldness, enhance one's appearance, and improve self-confidence. Follicular unit extraction (FUE) is a popular hair restoration procedure with natural outcomes and a short recovery period. This article explores the vast world of FUE hair transplant surgery and answers some of your frequently asked questions.
What Is FUE Hair Transplant Surgery?
Follicular unit extraction, commonly known as FUE, is a type of hair transplant surgery that involves extracting individual hair follicles from the donor area and moving them to parts of the scalp that have little or no hair. The newly transplanted follicles are nourished by minerals in the blood and regrow in their new location.
FUE procedure is mainly used to reconstruct the frontal hairline, restore the crown, and lower a high hairline. This method has gained more popularity in recent years as its risk of infection, visible scarring, hair plugs, and excessive bleeding is almost negligible. It is also noteworthy that the success rate of this cosmetic procedure is more than 95%, and its results are life-long.

How to Prepare for FUE Hair Transplant?
Pre-operative instruction for FUE hair transplant is similar to other hair restoration surgeries. In the following, some of the most important points about what to do before this cosmetic procedure are mentioned.
- Avoid smoking for at least three days before the operation, as it can delay the healing process and cause severe scarring;
- Do not drink alcoholic beverages, even light ones, from a week before the procedure as it may cause bleeding during and after the surgery;

FUE Hair Transplant Procedure
FUE hair transplant surgery initiates with numbing the scalp with lidocaine or other proper anesthetics. Afterward, the surgeon shaves the whole scalp and removes one to four hair follicles from the donor area using a specialized micro punch instrument and focused LED light. After extraction, the surgeon makes tiny cuts (with a length of 1 mm) on the receiving area with a needle or surgical knife and then transplants the harvested follicles in the incisions. Since this operation is sutureless, the cuts are cleaned and disinfected with a sterile solution, and the whole scalp is bandaged.
What to Expect after Follicular Unit Extraction?
The first week after the FUE hair transplant is the hardest, as the scalp is painful, itchy, and swollen. You must book an appointment the day after the operation so your surgeon can remove the bandages and check your transplanted grafts. Most patients feel fine within three days and can get back to work. If you have severe pain, bruising, and numbness, take a few more days off and rest at home.
FUE Recovery Timeline
The recovery period of follicular unit extraction takes two to three weeks, but its results take more time to reveal. This section discusses different stages of FUE recovery and provides useful tips on recovering faster.
The first week after the surgery
During the first week, your scalp is tender, bruised, itchy, painful, swollen, and red, but by the end of the week, most of these discomforts are gone, and you feel fine again. For the first 48 hours after the surgery, your scalp should remain dry as the new follicles are fragile and sensitive to infection. You can gently wash your head with lukewarm water and an unscented shampoo two days after the surgery. Scrubbing the scalp and hitting the new grafts (with fingers or water) ruins the follicles and causes them to fall.
It should also be noted that any activity that raises your blood pressure or makes you sweat should be avoided during the first week. Avoid vigorous activities, drinking, and smoking until your doctor allows you. Also, you should be aware of the signs of infection, such as fever, green puss coming out of the incisions, and unmanageable pain during the first week. Take your prescribed antibiotics as instructed.
Weeks two to three after the surgery
In the next two weeks, you feel less pain, itchiness, and tightness in your scalp, and the swelling subsides greatly. Therefore, you can get back to work and your daily routine. Remember that the new grafts are vulnerable, so avoid sun exposure, dusty places, and hurting the follicles. You can shower normally from the beginning of the second week, but you still need to use baby shampoo. Most newly transplanted hair will fall off during this period, but there is nothing to worry about because the follicles are still under the skin and will regrow a few weeks later.
Weeks four to eight after the surgery
The new grafts are still resting in this period, and you will look the same as before the operation. By the end of the 8th week, small white spots will emerge on your scalp, which shows that the new hair is growing. You can resume your physical activities from the fourth week onwards, but avoiding swimming for the next two months is suggested, as the chlorine added to the water can harm the follicles.
Week nine and beyond
At the beginning of the third month, you probably can see new hair growing in the recipient area. Sometimes, it takes four months for the new grafts to regrow, so if you haven't seen new hair after three months, don't lose hope. The new hair is delicate, thin, and less compact, but the hair gets denser, longer, and thicker as time passes. Meanwhile, trimming, combing, brushing, curling, and weaving of new grafts should be done with lots of caution as the grafts are very vulnerable. Moreover, it's better not to wear hats and pullover clothes for four months as they may harm the new hair.
FUE Hair Transplant Results
The natural and realistic results of the FUE technique have made it one of the world's most popular hair restoration techniques. If this operation is done by the hands of an experienced and artistic surgeon, its outcomes are remarkable and life-long. Usually, the surgeons map the hair growth before the operation to know where to place each follicle. By doing so, the hairline is naturally restored, the angle of grafts is right, and the new hair feels and looks more normal. Although the outcome of FUE is visible 8 to 10 months after the procedure, the final results are revealed within 12 to 18 months.

FUE Risks and Side Effects
Common side effects of FUE include:
- Mild to moderate pain;
- Minor bleeding;
- Shock hair loss;
- Numbness of scalp; and
Rare risks and complications of FUE also include:
- Formation of hard crust on the scalp;
- Severe bleeding;
- Permanent numbness;
- Balding or thinning of hair after the procedure; and
- The unusual look of the hair pattern.
FUE Failure: Causes and Symptoms
The failure rate of FUE hair transplant surgery is less than 10%, and it may be caused by various factors such as stress, unhealthy lifestyle, poor post-operative care, smoking, taking certain medications that interfere with the procedure, lack of surgeon's experience and expertise, and poor nutrition. The first and most important signs of FUE failure are the abnormal distribution of grafts, low density of hair in the recipient area, unnatural hairline, and developing keloids or visible scars in the donor area.
What Is the Difference between FUE and FUT?
FUE is an updated and less invasive version of FUT. In follicular unit transplantation (FUT), the surgeon removes a thin, long strip of skin from the donor area and then harvests the hair follicles using a powerful magnifier and surgical tools. In FUE, however, tiny cuts remove the follicles directly from the donor area.
FUT involves large cuts and incisions on the scalp, so the surgeon has to stitch the skin before wrapping it with a bandage. However, in FUE, small incisions are made by punctual tools, and there is no need for suturing the donor and recipient areas. Remember that sutures increase the risk of infection and scarring and prolong the healing process.
What Is FUE Mega Session?
In the FUE mega session, the surgeon removes and transplants more than 2,500 grafts in a single session. Usually, this method takes 10 to 12 hours and is used for patients with a very good donor area, foreign patients who need to get the treatment in one day, and those who need faster results. However, this operation is more expensive than normal FUE and requires the mastery of one or more surgeons and a qualified surgical team.
