For many men, the first sign of hair thinning is not a sudden loss, but a gradual change in texture—a feeling that the hair is becoming finer, more fragile, and less dense. Even as the biological clock of a hair follicle is largely predetermined, emerging medical protocols are shifting the focus from simply stopping loss to actively improving the quality of the hair that remains. Through a combination of bio-stimulation and regenerative medicine, specialists are finding that se consigue un cabello más grueso, resistente y saludable.
Understanding the science of hair requires looking at the follicle’s lifecycle. According to the Asociación Española de Dermatología y Venereología, every hair passes through three distinct stages: the anagen (growth) phase, which lasts between two and six years; the catagen (resting) phase, lasting about three weeks; and the telogen (falling) phase, which spans three to four months. During this final stage, We see considered normal to lose between 80 and 100 hairs per day.
However, when the growth phase shortens or the follicle weakens, the resulting hair is thinner and more prone to breakage. Dr. Elena Caride, an aesthetic physician with a master’s in trichology and hair transplantation and medical director of the Croma laboratory, has observed an increasing number of men visiting her clinic in Alicante seeking to reverse this process. Rather than a one-size-fits-all approach, she categorizes the most effective interventions into three distinct pathways: preventive strategies, active alopecia treatments, and supportive care for hair transplants.
The Role of Polynucleotides in Hair Prevention
For those in the early stages of thinning, the goal is bio-stimulation. One of the most innovative tools currently used is polynucleotide therapy. This process involves infiltrating the scalp with purified DNA fragments derived from salmon trout. These polynucleotides function as regenerative bio-stimulators, designed to strengthen the hair follicle while improving both oxygenation and nutrient delivery to the root.
The objective of this preventive approach is to ensure that the hair emerging from the follicle is structurally sound. Dr. Caride explains that the result of these protocols is “un cabello más grueso, resistente y saludable.” To achieve this, the standard clinical protocol typically involves three initial sessions spaced one month apart, followed by maintenance sessions every six months.
These injections are rarely used in isolation. To amplify the regenerative effect, clinicians often integrate medical technology during the same session, such as capillary radiofrequency and phototherapy. For continued care at home, the apply of topical exosomes in the form of hair serums is often recommended to maintain the scalp’s health between clinical visits.
Addressing Diagnosed Alopecia with Autologous Factors
When a patient has already been diagnosed with alopecia, the clinical objective shifts from prevention to stabilization and densification. In these cases, doctors often turn to autologous growth factors. This technique uses the patient’s own biological material to trigger a healing response in the scalp.
The process begins with a blood draw from the patient. This blood is then centrifuged to isolate a high concentration of fibrin-rich growth factors. Because these factors are autologous—meaning they come from the patient’s own body—they are highly compatible and effective at reducing inflammation and strengthening the follicle. The treatment follows a similar initial rhythm of three sessions, one month apart, with maintenance required every three to six months depending on the patient’s specific needs.
The primary goal of this intervention is to halt active hair loss and increase the overall density of the hair, effectively “waking up” dormant follicles or reinforcing those that are miniaturizing.
Optimizing Hair Transplants Through Bioregeneration
Hair transplantation is often viewed as a final solution, but the success of the graft depends heavily on the condition of the recipient tissue. Bioregeneration treatments are now used as “coadjuvant” strategies, meaning they support the transplant both before and after the procedure.
In the preparatory phase, polynucleotides are applied to the scalp—usually three sessions starting at least two weeks before the surgery. This prepares the tissue, improving its response and optimizing the subsequent scarring process. By improving the “soil” in which the new follicles will be planted, the likelihood of graft survival increases.
Following the transplant, the protocol shifts to fibrin-rich growth factors. These are applied to manage the inflammatory response and accelerate the healing of the scalp, which ultimately enhances the aesthetic and functional results of the transplant.
Comparative Overview of Capillary Strategies
| Strategy | Primary Tool | Main Objective | Typical Timeline |
|---|---|---|---|
| Preventive | Polynucleotides | Follicle strengthening | 3 initial sessions $rightarrow$ 6-month maintenance |
| Active Alopecia | Autologous Factors | Halt loss / Increase density | 3 initial sessions $rightarrow$ 3-6 month maintenance |
| Transplant Support | Polynucleotides & Fibrin | Tissue prep & healing | Pre-op (2 weeks) and Post-op recovery |
Beyond clinical interventions, daily maintenance plays a critical role. While professional treatments address the follicle, topical products like specialized shampoos, serums, and conditioners help protect the hair shaft from environmental damage and maintain the health of the scalp’s microbiome.

As regenerative medicine continues to evolve, the next milestone in trichology is the refinement of exosome therapy and the integration of more precise genomic mapping to tailor treatments to an individual’s specific genetic predisposition to hair loss. These advancements suggest a future where hair health is managed with the same precision as any other organ system in the body.
