Although hair transplantation has been applied for many years, after the recently developing technology and increasing medical experience, hair transplantation procedures can now be solved easily and at a more affordable cost than before.

In general, different techniques are applied in hair transplantation, which is defined as another transplantation of hair follicles taken from the back of the head. Costs vary depending on the size of the area to be transplanted. However, this is not the only factor.

Types of Hair Transplants

First of all, it is determined which technique will be used for the area to be transplanted. This is FUSS (follicular unit strip surgery) or FUE (follicular unit extraction). This is usually done in clinical settings or in private surgical areas in doctors’ offices. As the first procedure, your scalp is cleaned and your procedures are started by injecting medicine to numb the back of your head.

If the FUSS technique is to be used, your doctor will remove a 6 to 10-centimeter scalp strip from the back of your head and put it aside, and cover the removed area. It covers this area with the surrounding hair bristles. The operations team then divides the 6 to the 10-centimeter strip of scalp, which is removed from the back of your head, into 500 to 2000 micro-pieces each containing hair cells (hair strands). These parts are called grafts. The number of these grafts varies depending on the quality, type of hair cells, and the size of the area to be transplanted.

But; If the FUE technique is to be used, the process presses will be slightly different. This time, your doctor will start the operation by shaving the area from the back of your head where the hair strands will be transplanted. The hair follicles to be transplanted afterward will be removed one by one from here. This area will heal in small spots.

How Does Direct Hair Transplant Work?

Direct Hair Implantation (DHI) is a modified version of FUE hair transplantation and includes similar process steps.

The rest is the same in all techniques. The prepared grafts or hair follicles are transferred to the transplant area, which is cleaned and made ready for operation. Of course, before the area is cleaned and numbed. With the scalpel needle half, small holes are created. Grafts or hair follicles are placed in these prepared points. Depending on the size of the area to be transplanted, these procedures can take between four and eight. Some transplants may not be fully successful. Such situations may require additional.

Who needs the DHI procedure?

Androgenic alopecia patients, the most common type of hair loss, are the best candidates for hair transplantation. This condition is often referred to as male or female pattern hair loss.

If these items are suitable for you, we can assume that your hair transplantation process will be successful in general. These:

  • Age People who have a hair transplant must be over the age of 25. Before this age, hair loss is more unpredictable.
  • Hair diameter People with thicker hair usually get better results than people with thinner hair. Thicker hair provides more protection to each hair follicle.
  • Donor density Patients with hair density below 40 follicles are considered weak candidates for hair transplantation per square centimeter in donor areas.
  • Hair color People with light or close hair color usually achieve the best results.
  • Expectations People with realistic expectations are likely to be satisfied with the results.

DHI vs FUE and FUT hair transplantation

DHI, FUE, and FUT involve the transplantation of hair follicles taken from a part of your scalp to other areas that are balding or sparse.

During FUT surgery, a surgeon cuts a long, narrow strip of skin behind your scalp. Hair follicles are taken one by one and transplanted along your hairline. This method is usually the fastest and cheapest, but it can leave a long scar. The scar can be noticed if you wear your hair short, but long hair often hides it.

In DHI and FUE surgeries, individual hair follicles are taken directly from your scalp. During FUE, a surgeon manually cuts a series of channels in your scalp to insert the hair follicles. The DHI technique allows surgeons to make these incisions and to transplant hair at the same time.

DHI and FUE are less damaged in terms of scars caused by FUT, but these operations often take longer and are more costly.

Companies offering DHI claim that this is the most advanced and effective hair treatment option. However, there has been no study comparing the results with other hair treatment techniques.

Any FUE surgery can be successful in the treatment of hair loss. However, there is some controversy about this: whether FUT or FUE is the more effective method.

Side effects and precautions of DHI hair implantation

Hair transplant surgeries are relatively safe and rarely cause complications. DHI and FUE are less invasive than FUT because a surgeon does not need to cut a large strip of skin.

Doctors usually state that the FUE technique does not leave scars, but they still cause a series of small scars from the removal of individual follicles. These scars are usually not noticeable.

The most common side effect is scarring, and this cannot be avoided with any procedure.

Other potential side effects include:

  • infections
  • crust or pus drainage around the surgical sites
  • scalp pain, itching, and swelling
  • inflammation of hair follicles (folliculitis)
  • bleeding
  • losing sensation around the surgical sites
  • visible areas of hair that don’t match the surrounding hair or are noticeably thinner
  • continuing to lose hair if your hair is still balding

Minoxidil and Propecia can also have side effects, such as:

  • irritated scalp
  • dizziness
  • chest pain
  • headaches
  • irregular heart rate
  • hand, foot, or breast swelling
  • sexual dysfunction

Finally, the “Direct Hair Implantation” method is one of the most reliable and successful methods. If you have hair loss or hair loss problems, you can choose this DHI method with peace of mind.
