Follicular Unit Transplantation (FUT) is a surgical procedure. This procedure refers to the hair transplantation from back of the head to the balding zone. Back of the head is resistant to hair fall. This is the reason why back of the head is chosen as the donor area by the hair surgeons.
Hair is transplanted in a way that the balding area looks natural.
The scalp of the patient is anaesthetised before removing a strip of tissue from the area. After the removal, this tissue is cut into many follicular units. This is done using a technique known as microscopic dissection.
The arrangement of the follicular grafts decides the quality of the aesthetic of the transplantation surgery. This positioning is determined based on the hair loss history of the patients. Follicular units reflect the natural growth of hair. Therefore, these units are used to cover the affected area of the patient’s head.
Since the ancient age people believed that hair on the scalp grows as individual strands. However, this is a wrong perception as hair grows in groups. The groups of the hair are called follicular units. Even after the discovery of the little groups of hair, the surgeons were reluctant to use these for hair restoration.
Later the concept of FUT was introduced in the hair surgery process. These units are not merely groups of hair. These contain blood vessel, muscle and nerves. Entire unit is wrapped in collagen. The collagen gives the units a different structure.
For maximum survival of hair and fullness of the volume, surgeons keep the hair group intact. The follicular units are very small. Due to this, expertise of the surgeon is required to keep these units from getting damaged or torn during the surgery.
Microscopic dissection is one of the most important aspects of this surgery. The dissection isolates the hair group from the donor area without damaging or breaking them. Keeping the unit away from damage requires excellent surgical skill.
Slivering is the first step of the dissection. In this step, the surgeon disassociates the donor strips into tiny sections. This is achieved by bypassing scalpel blades through the gap around the hair group.
Surgeons, who are performing the surgery, do not cut through the hair tissues. The technique produces small pieces of hairs with undamaged tissues.
There is an array of solutions available for storing the hair grafts while the surgery takes place. Proper preservation of the grafts is important to ensure hair growth and maintain visibility.
This procedure takes an entire day to perform. This surgery is usually performed under local anaesthesia and sedation. After giving you a mild sedative, your scalp will be numb and the doctor will remove the donor strip. Once the removal is done, the strip will be divided and placed for microscopic dissection.
As the hair is harvested, the surgeons make tiny recipient sites on the balding area. The hair group graft is placed in this balding area with fine surgical instruments. After placing the graft, it is essential to clean the scalp.
At the last stage when the graft is placed properly, the positions will be checked once again. Since bandage or dressing is used on the operated area, you can wear a baseball cap to cover it for the time being.
After the surgery
You can go back to your normal life after the second day. Some complication may arise after the surgery is over. Poor hair growth is the most common after effect of the surgery. This can be taken care of by consulting the doctor.
Before opting for the surgery, you need to find information about the hair transplant cost. Different surgeons may have different charges. It is important to find a well known and established surgeon for the surgery.
