Although the hair transplant procedure is considered relatively safe and minimally invasive, not everyone can benefit from it. There are a number of contraindications that can exclude a patient from the procedure or require its postponement. Below are the most important situations when is hair transplantation contraindicated.

Autoimmune and inflammatory diseases of the scalp

One of the most common contraindications to hair transplantation is scalp diseases such as psoriasis, lupus erythematosus or lichen planus. With these conditions, the skin may be permanently irritated and the hair follicles may be damaged or unable to accept transplanted hair. Transplantation performed during the active phase of the disease can lead to graft rejection or recurrence of symptoms.

Advanced baldness and insufficient donor area

In order to perform a transplant, a so-called “donor area” is needed – most often the back and sides of the head, where the hair is less susceptible to the hormones responsible for androgenetic alopecia. If the patient suffers from advanced hair loss and there are not enough healthy follicles in the donor area, it may not be possible to perform a successful transplant. In such cases, the doctor may advise against the procedure or suggest alternatives, such as scalp micropigmentation.

Unstable androgenetic alopecia

Hair transplantation in people whose balding process continues to progress can lead to uneven aesthetic results. The newly transplanted hair will remain, while the natural hair may continue to fall out, making the hairstyle look worse over time. For this reason, many specialists recommend that the procedure be performed only when baldness is relatively stabilized – often after drug treatment (such as finasteride or minoxidil).

Endocrine disorders

Hormonal disorders, such as hypothyroidism, polycystic ovary syndrome (PCOS) or adrenal problems, can affect hair condition and the effectiveness of the transplant. In such cases, hormonal balance should first be stabilized before the patient is qualified for the procedure.

Systemic diseases and coagulation disorders

Diabetes, heart disease, hypertension or blood clotting disorders are important contraindications to hair transplantation. Although some of these conditions do not completely rule out the procedure, they require prior consultation with the attending physician and very careful medical preparation. If you have unregulated diabetes or are taking anticoagulants, the risk of complications after the procedure increases significantly.

Pregnancy and lactation period

Pregnancy and lactation are periods when hair transplantation is not recommended. Hormonal changes occurring during this time can affect the quality and cycle of hair growth, and some of the agents used during the procedure may not be advisable for pregnant women.

Inappropriate patient expectations

Although it is not a medical contraindication, it is equally important for the patient to be realistic about the results of the procedure. Hair transplantation does not always produce spectacular results and will not recreate the full density of years ago, especially in people with extensive baldness. People with obsessive-compulsive disorders about their appearance (such as dysmorphophobia) may not be good candidates for the procedure for psychological reasons.

Addictions and inappropriate lifestyles

People who abuse alcohol, smoke cigarettes or use psychoactive substances may have a worse prognosis after hair transplantation. Nicotine and alcohol negatively affect blood circulation, which can impede proper blood supply to the scalp and impair the healing process. Toxic substances present in the body can also negatively affect the acceptance of transplanted hair follicles. Therefore, patients with unhealthy lifestyles should first take steps to improve their overall health before opting for the procedure.

Young age of the patient

Age can also be a factor in determining the feasibility of transplantation. In very young patients, especially those under the age of 25, the balding process is most often not yet complete. In such a case, performing a transplant may have a short-term aesthetic effect, but as the baldness progresses, there may be a need for further treatments. For this reason, doctors often recommend drug treatment for young people and observation of the progress of the disease before deciding on transplantation.
