Surely in your research you have found a lot of information about the donor area and have wondered what happens to a graft with a poor donor area?
The donor area or donor area is key to establishing a treatment plan in a transplant of hair. For various reasons, sometimes the donor area may become insufficient or it may not have the characteristics to ensure the best result.
Importance of the Donor Area
El hair graft It has always had several relevant challenges, one of them is the donor or donor area. As you surely know at this point the limit of the number of surgeries, as well as the amount of hair to be transplanted is given by the extraction area.
Our ability to extract follicles from the donor area has allowed the technique to evolve to limits that in the past would seem unthinkable.
Currently, thanks to novel techniques and their combination, there are surgical teams that report the extraction of up to 9,000 Follicular Units in a mega session; Whether this is the best or not is another matter, but we have come this far.
Then the donor or donor area plays as we can see a primary role in the success and achievement of expectations of patients in hair transplant.
Now, let's go back and understand more about the area that allows us to extract donor hair ...
What is a Donor Zone?
The perfect donor area is located on both sides and at the back of the human scalp. Permanent hair growth is not affected in these areas as these hairs are mostly immune to the effects of DHT.
Factors such as the texture, size, color and curl of the hair follicles extracted from the donor area play an important role in determining the final result after transplantation.
Even if the hair transplant is performed by the best transplant specialist, the results are also determined by the quality of the hair, since we only work with the hair, we simply transfer it from the back of the head to the bald area.
Therefore, preoperative consultation Before the procedure you should determine these important characteristics before recommending a hair transplant.
What is a good donor area for hair transplantation?
- When choosing the donor area, doctors prefer hairs from the scalp in the occipital area and adjacent temporal areas. This is because the hairs that grow in these areas are permanent.
- The next preferred donor area is the beard, as his hair is naturally thick and resistant to DHT. The hair transplant specialists They usually mix hair from the scalp with that of the beard, but the art of hair transplantation dictates that they should not be used in (a) along the front line of the hair and, (b) in the crown area due to to their nature.
- Hair from the abdomen and chest can also be used as donor hair. Although they are fine, for the most part, in some they are thick enough to resemble the hairs on the scalp.
- In our DrEO Clinic, chest hairs are used exclusively to increase the number of grafts in those who are extensively bald. Chest hair is also recommended to smooth a hairline, this if you have a poor donor area.
- Limb hair (upper and lower limbs) is the last resort, but for most people it is so fine that it is barely visible on the scalp when worn. Because their growth cycle is long and unpredictable, they are least preferred in body hair transplants.
- In Women only the hair of the scalp is used.
Hair transplant techniques
Although the FUE (Follicular Unit Extraction) Technique is the most common and preferred method for hair transplantation, the FUT (Follicular Unit Transfer) Technique is an option in some cases. They only differ in the technique of extracting follicles from the same permanent area of the scalp. Both techniques are very effective and have high success rates in the best hands.
These two treatment procedures require the surgeon to remove healthy hair grafts and place them in tiny incisions in the parts of the scalp affected by the baldness.
The incisions are strategically positioned and distributed in such a way that the receiving areas as they grow, blend seamlessly with the native hair and create an illusion of fullness so that the patient does not appear to have a "head full of air."
Choosing donor sites for both techniques
The permanent zone is the same, whether you make a FUE procedure as if it is FUT preferred by the experienced / novice surgeon.
A horizontally oriented piece of elliptical skin measuring 12-15 cm (each hole in FUE is 0.7-0.85 mm in diameter in contrast) with some underlying fat totaling 1.5-1.8 cm (each punch or punch incision). FUE is 2-3 mm deep in contrast to the depth of FUT) it is cut with a knife.
In the FUT technique or of Tira there was the possibility of a visible linear scar that is sometimes bothersome for the carrier patient.
However, with the introduction of the minimally invasive FUE technique, there will be barely noticeable scarring after the hair is removed from the donor area.
In this technique, the surgeon removes and extracts the roots of the hair from the donor site one by one with the help of a micromotor. Some still do this procedure manually.
La robotic extraction It has not been successful nor is it economically viable.
Poor Donor Zone or Bad Zones for hair transplantation
It is important to realize that not everyone has a good donation site. Some people given the situation in their donor area may not be candidates.
Below we review some cases of donor areas bad or unworkable.
- Patients with previous surgeries with depletion or extensive extraction (up to 75% of the follicles in the donor area).
- Older patients with aggressive alopecia and who have a very small donor area, with this we refer to very rare cases that would even make us think on a scale beyond 7 Norwood.
- Men suffering from DUPA or diffuse alopecia without a pattern tend to have unhealthy hair. Therefore, they are not a suitable candidate for a successful hair transplant. Others may have extensive miniaturization of baldness (> 30%), which may also have spread to the permanent area.
- People who have a diseased donor supply are also a poor choice. These cases occur more in women than in men, given the prevalence of autoimmune diseases, mainly in the female sex.
- Cicatricial Alopecia due to scarring as a consequence of reasons sometimes not well understood or due to lack of diagnosis.
- People with thin hair are also not the best candidates, since the caliber will also be a predetermining factor in the success of the hair implant.
- Donor sites before 25 years of age can be considered a bad decision since we have no idea if these hairs will remain. Therefore, it is often advisable to tell the patient to wait until she is 25-27 years old.
Caring for the donor area after surgery
After completing the root extraction process, the surgeon sterilizes and adequately covers the donor area to prevent bleeding or infection.
Analgesics and antibiotics are often recommended to patients in case they experience any irritation or pain in the donor area.
After one or two days after the operation, the surgeon removes the bandage and cleans the affected area. Any minor blood clots or scabs will disappear within a week.
