Hair graft risks: Is the intervention safe?

Although hair grafting is a safe intervention, as with any medical treatment, it can have certain negative effects on the person. Knowing the possible risks of hair grafting is important to consider any adverse situation that may occur and, above all, how to avoid them.

From Hospital Capilar We will tell you about the possible risks of hair grafting if good surgical practices are not carried out or a correct postoperative period is not carried out.

Is a hair transplant safe?

When in doubt as to whether a hair graft is safe, the truth is that it is a minimally invasive outpatient intervention not considered risky. It is a safe and effective technique that offers satisfactory results for the patient.

However, despite being a surgery that is safe and does not present significant risks for the patient, it is necessary to contemplate certain situations that may occur when the technique is not adequate or a correct procedure is not carried out. postoperative after hair implant.

Development of infections

During the hair graft, small openings and incisions are made in the scalp to extract and implant the necessary follicles. These are still small open wounds that, if they are not disinfected and treated properly or are made with inappropriate material, can be the source of infections. When this happens, it is enough to take antibiotics prescribed by the doctor and proceed with the disinfections as established by the health team.

In case of originating some type of infection, normally it is folliculitis which does not pose a serious risk to health, but it does to the survival of the grafts. This is why, in these cases, the doctor supplies antibiotics to deal with the infection.

Allergic reaction

Among the possible risks of hair grafting are adverse allergic reactions both to surgical material and to the substances that are supplied during surgery. This is avoidable by carrying a correct preoperative where the medical team writes down the possible allergies that the patient may present, as well as the tolerance to the Anesthesia local used during surgery. Therefore, among the risks of hair grafting, it is one of the least frequent.  


It does not usually happen very frequently, but it may be the case that the patient experiences an episode of bleeding in the scalp. When a small amount of blood accumulates in the scalp, the body itself tends to reabsorb it. However, when it comes to more intense bleeding, it is necessary to resort to emergency treatment to absorb that accumulated blood. Otherwise, it may affect the healing process.

The appearance of bleeding in the scalp is avoided by following all medical indications in relation to the preoperative period, where you must stop consuming certain medications and substances to avoid this, as well as during the postoperative period.

Reaction to anesthesia

In a hair transplant it is not necessary to provide general anesthesia, only local anesthesia of the same type used in dentists is used. Once again, the medical team makes sure that the patient does not present intolerances to these types of substances.

On the other hand, the side effects derived from anesthesia such as dizziness, vomiting or nausea do not usually occur since it is administered in very little quantity, thus considerably reducing the chances of intolerances. However, in the face of any type of symptom, the medical team is prepared to react and care for the patient.

Swelling and bruising

Among the risks of hair grafting, inflammation and bruising are usually more frequent. The severity of this is minimal and as the days go by and following the medical instructions, the inflammation and possible bruising will disappear.

This occurs when the liquids supplied during surgery go down to the face, causing it to swell. This is why you should use a tape after hair transplant during the first night and do not lower your head during the first days. In this way, liquids and substances do not go down to the face and the body will proceed to eliminate them through the lymphatic system.

pain and stinging

It can be considered more of a side effect derived from the surgery, but we can also place it among the risks of hair transplantation. It is common for the patient to experience certain discomfort during the first days after the intervention, such as itching or stinging. This is completely normal and, to alleviate it, we must apply every two hours both in the donor area and in the recipient area. thermal spray, which will hydrate and refresh the area. 

Poor healing

El hair graft with FUE technique it does not leave visible scars since it does not require the extraction of skin from the scalp. However, the so-called fuss technique It is done by removing a strip of the patient's scalp, which creates a scar in the donor area. In these cases the patient may not heal the area correctly. However, this method is not currently used precisely for this reason. 

Keys to reduce the possible risks of hair grafting

The risks of hair grafting, as we have seen, can be avoided and in any case treated hands of a suitable medical team and expert in hair medicine. To reduce these possible risks it is very important to know where to perform the hair graft. For this, we give you some keys to take into account to minimize the development of some of these risks of hair grafting.

Avoid low cost hair transplant

Currently it is very common to go to clinics, especially outside of Spain, where they offer the low cost hair transplant. It must be taken into account that the quality of the material used, having a experienced medical team and the services and facilities offered by a hair clinic with experience in Spain have a cost that is reflected in the price. When the price is lower than the average and if it is done in another country, we can expose ourselves in one way or another to the aforementioned risks of hair transplantation by dispensing with or reducing the quality of its materials, experts, services and facilities.

Need for an expert medical team

Although it is an outpatient and minimally invasive intervention, it must be a expert medical team who carries it out. We can consult the professional trajectory and results of the doctors of the hair clinics as a guarantee of health, safety and good practices.

Check real cases of clinic patients

Finally, it is very helpful to know the experiences of real patients from the clinics that are of interest to us. To do this, we can consult Google reviews, as well as see on social networks or clinic websites the cases before and after hair transplant.
