Hair grafting techniques

Hair implantation techniques

What types of hair grafting techniques are there and which one is better?

In recent years there has been an advance in the hair sector in terms of medical equipment, technology and hair grafting techniques and results in hair implants. 

However, the most important factor will always be the state of the scalp and how advanced the alopecia is in order to obtain a satisfactory natural result for both the clinic and the patient.

In order to better understand the hair grafting techniques that exist, it is necessary to be clear about what hair grafting is and how it is done. 

Hair grafting is a conceptually simple method, which consists of extracting follicular units from an area of the scalp where hair grows strong and with good density (donor area) and implanting them in an unpopulated or bald area (recipient area). 

The transplanted hair maintains the genetic information of its area of origin, and with it the tendency not to be lost over the years.

Currently there are 3 techniques of hair grafting, FUSS - FUT, FUE - DHI, and hair grafting technique with the ARTAS robot that differ from each other by the way in which the hair follicles (UFs) are obtained from the donor area. 

FUSS hair transplant technique

The FUSS - FUT (Follicular Unit Transplantation) technique. 

The FUSS or FUT technique is the hair grafting technique by which the follicles are removed by extracting a band or strip of skin about 20 cm long and 1 cm wide. 

It is one of the most traditional hair grafting techniques. 

The strip that is extracted contains a sufficient number of hairs to be carefully extracted and implanted in the bald areas later. After the extraction of the strip of skin, the cut is sutured.

The hair follicles (GRAFTS) are separated one by one using stereoscopic binocular microscopes. The stitches are removed after 12 days leaving a large scar if the patient has very short hair.


Results obtained with the FUSS - FUT technique

If we take into account that the average density ranges between 55 to 60 follicular units per cm2, between 1000 and 1200 follicular units will be extracted.  

That is to say, in a patient with low follicular density it would not be possible to remove more follicles, with the indicated cutting measures, for that it would be necessary to enlarge the cut, thus producing a larger and more unsightly scar.

Advantages of the FUSS - FUT technique

  • Quick removal, more comfortable for doctor and patient.

  • Removal of more follicular units in 1 single section.
  • No need to shave the hair.

Disadvantages of the FUSS - FUT technique

  • Complications of the scar, invasive technique.

  • Removal of the stitches 10-12 days after transplantation.

  • Scar of 20-30 cm in the donor area, unsightly, you can not use very short hair or shaved.

  • Follicular damage: more than 30% of the follicular units in the donor area can be damaged by the scalpel at the time of extraction, and in the microscopic dissection performed by nurses or assistants.

Consequences of the FUSS - FUT technique 

  • Post-surgical effluvium

  • Infection
  • Necrosis
  • Dehiscence (spontaneous opening of a sutured area)
  • Hyper- or hyposthesia
  • Unsightly scar

FUE hair transplant technique

The FUE technique is one of the most modern techniques and one that offers the best results today. It requires great experience and talent on the part of the surgeon and the team that accompanies him.

FUE = Follicular Unit Extraction or Follicular Unit Extraction 

In this technique the follicles are extracted one by one, where the hair surgeon or medical team chooses the follicles according to the demand to implant (1, 2, 3 or 4 hairs).

In the FUE technique the follicles extracted are from the donor area (Occipital and/or temporal). 


Results obtained with the FUE technique

The results obtained with the FUE technique are natural looking, without scars and without fibrosis of the scalp as in the Strip technique.

Thanks to the implantation with the implanters used in this technique we can achieve maximum density. Implantation technique known as DHI.

Currently, between 1200 and 2000 follicular units are extracted per day depending on the density of the donor area of each patient.  

The only drawbacks that cause more units are not extracted: 

  • patient fatigue 
  • availability of hair from the donor areas of the head and body.

For hair transplants with more than 2000 units (we recommend 2 consecutive days).
Thus we can transplant from 2000 to 3600 follicular units in 2 consecutive days depending on the donor area of each patient. 

During the surgery procedure no scalpels are used and no sutures are made, so there are no scars or stitches. The results obtained with the FUE technique are very good.

Advantages of the FUE technique

The FUE is one of the techniques of hair grafting that has greater advantage, this is thanks to the individual extraction process, the patient decides at all times the number of follicles or grafts to be transplanted in each session.

The FUE technique allows us to select the follicular units that provide greater density. It is possible to extract hair from a larger area, even in patients with lower density it would be possible to extract more follicular units per session than with other methods or techniques.

  • There is no suture or visible signs of the transplant.
  • No band or strip of hair is extracted.
  • There are no stitches and no scalpel is used at any time.
  • No noticeable scars.
  • Long, short or very short hair can be used.
  • Post-operative with very fast recovery.
  • Hair from different parts of the body can be used (BHT - Body Hair Transplant).
  • Sections of more than 3600 follicular units can be programmed (depending on each patient, limited only by the donor area).
  • Selection of follicular units according to the demand necessary to cover the baldness.
  • Use of micro surgical instruments with caliber (0.75, 0.8, 0.85 and 0.90) for the extraction.
  • Healing of the micro extraction stitches in 4-5 days.
  • No risk of nerve or vascular involvement.
  • Removal with regular symmetry, leaving the hair uniform.
  • No follicular unit is damaged during extraction.
  • No special maintenance of the new hairs is necessary, since after their growth they will behave as completely natural hairs.

Disadvantages of the FUE technique

  • The extraction is 1 to 1 follicular unit so it takes longer with this method.
  • It needs more skill and experience of the hair surgeon.
  • The hair must be shaved, sometimes a hair transplant can be performed without shaving.
  • Texture: More difficult if the hair is curly.
  • Tightness: The finer the hair, the more difficult.
  • Hair color: White hair is more difficult to remove.

All modalities are possible and the patient will decide what suits him/her, depending on his/her free time, vacations, economy, or any other reason.

What are WHITE DOTS?

WHITE DOTS are micro white dots that are seen when the hair is completely shaved (with hair clippers). WHITE DOTS will only be noticeable if the patient's hair length is 1 mm or less.

In order for WHITE DOTS not to be too noticeable, the medical surgeon uses 2 strategies:

  • The use of smaller caliber microsurgical instruments in the areas of transplantation, In this process a greater skill of the physician is needed.
  • Another strategy is the use of the MFU technique associated with the FUE method. The MFU technique is the process of searching for multiple follicular units in which one unit is extracted leaving another, thanks to this technique there will be hair in that space reducing the visible effect caused by WHITE DOGS.

Artas hair transplant technique

The Artas hair graft is one of the most technologically advanced hair transplant techniques.  Its main value is the intelligence of a robot that collects the hair follicles from the donor area for subsequent implantation in the recipient area. 

The hair surgeon or specialist doctor can supervise and perform the appropriate interventions during the surgery. 

This innovative extraction technology integrates automation in the process of obtaining follicles. This allows for a reduction in procedure time and enables customized harvesting techniques to be applied over a larger area. 

In addition, thanks to the hair grafting offered by the Artas robot, it can allow transplanted follicles to have a higher survival rate and minimize the impact on the donor area.


Results obtained with the Artas robot

Your hair will grow naturally until the final result is achieved after twelve months, you will feel good again and you will enjoy your image as always. 

Everything is guaranteed by a professional medical team you can trust, Clínica de Freitas.

Advantages offered by the Artas robot in hair grafting

The main advantages: 

  • Shorter intervention time when extracting by Artas robot.

  • Suitable to cover medium to large areas.
  • Does not leave linear scars
  • Shorter postoperative period
  • Suitable for people who want to shave their hair.
  • Suitable for women

Hair grafting with Robot Artas is ideal for those doctors who do not have experience or knowledge to be able to perform a hair transplant with the FUE technique manually.

Final conclusion

In the vast majority of cases and patients, the hair transplant will last forever and as long as they do not stop the medical treatment (medication). 

At Clínica de Freitas we are specialists in the FUE technique, with the FUE method the hair will grow in the usual direction with its own inertia, which makes the result more natural.

The hair implanted with FUE technique will cover as much as possible the most fallen or sparsely populated areas of the scalp, keeping the healthy and donor areas in perfect condition. 
Through a quality intervention, 90% of the implanted hair can be used for life. You can visit our hair transplant clinic in Barcelona and our hair clinic in Valencia, Clínica de Freitas gives you the opportunity to show off your hair as before.
