Exosome & Stem Cell Hair Treatment
Exosome and stem cell hair treatment is a supportive approach to hair loss based on applying nano-sized extracellular vesicles (exosomes) secreted by stem cells to the scalp. These vesicles carry growth factors, proteins and signalling molecules; the aim is to support the cellular environment around hair follicles that have not yet fully disappeared. At Zen Poliklinik, the treatment is planned by a physician after a detailed hair and scalp assessment.
What Is Exosome & Stem Cell Hair Treatment?
Exosomes are microscopic vesicles naturally secreted by stem cells (most commonly of mesenchymal origin) that enable cell-to-cell communication. They contain growth factors, cytokines and various signalling molecules. Products used in hair treatment are produced under laboratory conditions and applied to the scalp by injection or microneedling. Because no tissue or blood sample is taken from the patient, the logic of the procedure differs from PRP and autologous micrograft methods.
Why Does Hair Loss Happen?
The most common cause of hair loss is androgenetic alopecia, a progressive process driven by genetic predisposition together with the hormone DHT. Iron deficiency, thyroid disorders, vitamin D and zinc deficiency, post-partum hormonal changes, severe stress, rapid weight loss and certain medications can also contribute. Identifying the underlying cause is essential for the right treatment decision, which is why a comprehensive assessment precedes any application.
Who Is It Suitable For?
The best candidates are people in the early or moderate stage of hair loss, whose follicles have started to miniaturise but have not fully disappeared. Early Norwood stages in men and diffuse thinning with a widening parting line in women are typical examples. It can also be considered for patients who wish to support their existing hair after a hair transplant, or who are looking for additional support alongside PRP or mesotherapy.
Who Is It Not Suitable For?
No meaningful result is expected in areas where follicles have completely disappeared and the skin surface has become shiny and hairless. The treatment is postponed in cases of active scalp infection, untreated psoriasis or severe seborrheic dermatitis. It is not recommended for pregnant or breastfeeding women, people with uncontrolled systemic disease, or those with a known history of malignancy. Suitability is determined by the physician after a detailed examination and, if necessary, blood tests.
How Is It Applied?
The process begins with taking the hair and scalp history, a trichoscopic assessment and blood tests where necessary. On the day of the procedure the scalp is cleansed; the product is applied to the scalp either through fine-needle microinjection or together with a microneedling device. The procedure is performed in a clinical setting under physician supervision and typically takes 30-45 minutes. Patients can return to their daily routine the same day.
How Many Sessions Are Needed, What Is Recovery Like?
The protocol is individualised: some patients are offered a short series of sessions a few weeks apart, others a single session or an annual review. The number of sessions is determined by the physician based on the stage and speed of hair loss and response to treatment. Recovery is generally comfortable: mild sensitivity or redness may occur at the treated area for a few days and resolves on its own. It is recommended not to wash the hair for the first 24 hours and to avoid irritating the scalp.
When Will Results Be Seen?
Because the hair cycle follows a biological timeline, results do not appear immediately. A reduction in shedding is usually noticed within the first few months; visible improvement in hair thickness and density is generally assessable between the third and sixth months. Standardised angle and lighting are used for before-and-after photographs. Results vary from person to person; the treatment supports the follicle environment but does not stop the underlying genetic process of androgenetic alopecia.
How Does It Differ From PRP and Hair Mesotherapy?
PRP treatment involves injecting platelet-rich plasma separated from the patient’s own blood by centrifugation. Hair mesotherapy is based on delivering ready-made mixtures of vitamins, minerals and peptides into the scalp. Exosome and stem cell-derived products, by contrast, are laboratory-produced extracellular vesicles applied without taking any blood or tissue from the patient. None of the three methods compete with one another; they are complementary options that can be combined at the physician’s discretion.
Can It Be Combined With Hair Transplantation?
Yes. Hair transplantation is a surgical procedure that moves permanent follicles to areas where hair has been lost; the existing hair in non-transplanted areas remains genetically susceptible. Exosome and stem cell-supported applications can be planned before or after transplantation to help support this existing hair. The timing of the combination is decided by the physician according to the transplant date and the healing process.
How Does the Process Work at Zen Poliklinik?
At Zen Poliklinik, the process starts with a detailed history and scalp examination. Trichoscopy is used to measure hair shaft diameter and the rate of miniaturisation, and blood tests are requested if needed. Once the type and stage of hair loss are established, an individual plan is drawn up, clarifying whether the treatment will be applied on its own, combined with PRP or mesotherapy, or whether a hair transplant should take priority. Standardised photography is planned for objective assessment at the third and sixth month. You can visit our appointment page to book a consultation.
Frequently Asked Questions
What is exosome & stem cell hair treatment?
It is a treatment approach in which nano-sized vesicles (exosomes) secreted by stem cells, carrying growth factors and signalling molecules, are applied to the scalp to support the environment around hair follicles. No tissue or blood sample is taken from the patient.
Does this treatment replace a hair transplant?
No. Hair transplantation is a surgical procedure that moves permanent follicles to areas where follicles have completely disappeared. Exosome and stem cell-supported treatment aims to support existing, not-yet-lost follicles; it does not create new hair in an empty area.
How many sessions are needed?
The protocol varies by patient. Some patients are offered a short series, others a single session or an annual review. The exact number of sessions is determined by the physician after examination and trichoscopic assessment.
When will results be seen?
Because the hair cycle is a biological process spanning months, results do not appear immediately. A reduction in shedding is usually seen within the first few months, while visible improvement in density is generally assessable between the third and sixth months.
What is the difference between PRP and exosome/stem cell treatment?
PRP is an injection of platelet-rich plasma obtained from the patient’s own blood. Exosome and stem cell-derived products are laboratory-produced extracellular vesicles applied without drawing blood from the patient. The two can also be combined at the physician’s discretion.
Is the procedure painful?
Because the procedure is performed with fine-needle microinjection or microneedling, discomfort is generally limited. A topical anaesthetic cream can be used if needed. Mild sensitivity for a few hours afterwards is normal.
Who should not have this treatment?
The treatment is not recommended for pregnant or breastfeeding women, people with an active scalp infection, uncontrolled systemic disease, or a known history of malignancy. Suitability is determined during the physician’s examination.
What should I be careful about afterwards?
It is recommended not to wash your hair for the first 24 hours and to avoid intense exercise, sauna and swimming pools for the first few days. Any mild redness or sensitivity on the scalp resolves on its own; avoid scratching or harsh contact with the area.
