Healthy, thick hair is an integral part of our appearance and self-confidence, but due to various internal and external factors, hair loss has become a pressing issue for many people. Modern regenerative medicine offers an effective and natural solution—PRP and PRF injections for hair, which, using the patient’s own blood, can stimulate hair follicle activity and restore scalp health.
In the following article, Yevgeniya Vladimirova, a trichologist at the Adoria Health and Beauty Center, explains exactly how PRP and PRF injections work in cases of hair loss and what results they deliver.
In this article, you will learn:
- The essence of the method and differences: what plasma therapy is and how PRP differs from PRF injections.
- Mechanism of action: how growth factors in blood plasma can “awaken” dormant hair follicles and improve scalp blood circulation.
- Suitability and results: in which cases PRP and PRF therapy are most effective and how long a course of treatment is needed to achieve visible results.
What are PRP and PRF injections, and how do they differ?
Modern beauty care offers not only a wide range of procedures to improve skin condition and reduce signs of aging, but also innovative solutions for combating hair loss. Among these solutions, PRP (Platelet-Rich Plasma) and PRF (Platelet-Rich Fibrin) injections stand out in particular, as their high effectiveness is based on a completely natural approach—the use of the patient’s own blood for tissue regeneration.
At the beginning of the procedure, a small amount of blood is drawn from a vein, which is then centrifuged to separate the valuable plasma. The main difference lies in the extraction technology and the composition of the resulting material.
- PRP (Platelet-Rich Plasma): This preparation is obtained by centrifuging blood at a higher speed and adding anticoagulants to prevent the blood from clotting. The result is a liquid plasma with a high concentration of platelets, which ensures rapid and potent release of growth factors into the tissues immediately after injection.
- PRF (Platelet-Rich Fibrin): is obtained using a slower centrifugation mode and without any chemical additives. This allows for the preservation not only of platelets but also of leukocytes and stem cells, forming a natural fibrin matrix. This structure ensures a gradual and prolonged release of growth factors into the tissues (up to 7 days), promoting deeper regeneration.
When choosing PRP and PRF injections for hair, the doctor individually assesses the condition of the hair to determine which method will provide the best therapeutic effect in a specific situation.
How do PRP and PRF injections affect hair follicles?

The therapy is based on the ability of platelets in blood plasma to release growth factors (such as VEGF and PDGF), which act as powerful biological signals for tissue regeneration. It is precisely this targeted biostimulation that is the main reason why PRP and PRF injections for hair are able to deliver such remarkable results. When the preparation is injected directly into the dermis, or the middle layer of the skin, a complex regeneration chain is triggered that affects hair follicles on multiple levels.
- Improvement of microcirculation and blood supply: growth factors promote the formation of a new network of microcapillaries (angiogenesis) around the hair follicles. This ensures an increased supply of oxygen and nutrients, which is critical for hair health.
- Extension of the growth phase (anagen): the formula stimulates cell division and extends the active growth period, preventing hair from prematurely entering the shedding phase.
- “Reactivating” follicles: the active ingredients act on the stem cells at the base of the hair follicle, prompting dormant follicles to produce hair shafts again.
- Restoring hair density: the therapy helps combat hair miniaturization (reduction in diameter), making regrown hair thicker, stronger, and more pigmented.
Before starting therapy, it is essential to understand the cause of the problem. Although only a doctor can provide an accurate diagnosis, you can find valuable information about what affects hair health in the article “Why Does Hair Fall Out and When Should You See a Trichologist?”.
In which cases are PRP and PRF therapies for hair most effective?
Plasma injections are widely and successfully used to treat various trichological problems, but the best results can be achieved if treatment is started early. Specialists particularly recommend this method in the following cases:
- Androgenetic alopecia (genetic hair loss): for both men and women in the early stages, while hair follicles are still alive but have become less active.
- Diffuse hair loss: in situations where hair loss is caused by prolonged stress, poor nutrition, iron deficiency, or past viral infections.
- Improving hair structure: if hair has become brittle, dull, prone to breakage, or has lost volume.
- Scalp health issues: the treatment helps normalize the condition of the scalp, reducing dryness, itching, or seborrhea (dandruff).
The procedure is often recommended for women during the postpartum period, when increased and rapid hair loss is observed. If you’re also facing this problem, you’ll find valuable information for timely solutions in the article “Postpartum Hair Loss – How to Get Over It Faster”.
When might the treatment not deliver the expected results?
Although PRP and PRF injections are among the most effective methods for improving the health of the hair and scalp, they are not a miracle cure in all situations. It is important to realize that the procedure may not be effective if hair follicles have completely died and become overgrown with connective tissue (scar tissue forms)—in such areas where the scalp has been bald for years, it is no longer possible to stimulate new hair growth.
Similarly, the therapy may be less effective or contraindicated in certain autoimmune conditions (such as alopecia areata), acute inflammatory processes of the scalp, as well as in cases where the patient has blood clotting disorders or severe liver disease. This is precisely why a consultation with a trichologist is mandatory before starting the course.
What is the role of a specialist consultation?

To achieve maximum results, the first step is always a visit to a specialist. Many patients are unaware that hair health issues are addressed by a specific medical field. A qualified trichologist is a doctor who specializes specifically in the diagnosis, treatment, and prevention of hair and scalp conditions.
During the visit, the specialist performs not only a visual examination but also digital trichoscopy—a method that allows for high-magnification assessment of follicle viability, scalp condition, and hair density. Only a doctor can determine whether plasma injections will be effective in a specific case, or whether they need to be combined with medication and dietary adjustments to address the root cause of the problem rather than merely treating the symptoms.
When can results be expected, and how long is the treatment course?
It should be noted that hair growth is a slow physiological process, so PRP and PRF injections for hair do not provide an immediate visual effect. The first improvements—a reduction in hair loss—are usually observed after 2–3 procedures, but new hair growth and increased thickness become visible in about 3–4 months. A full course usually consists of 3 to 6 treatments at 3–4 week intervals, followed by maintenance therapy once every six months or once a year.
