How is the Regenera Activa treatment performed?

The procedure is done in-office under local anesthesia. Small tissue micro-samples are harvested from the back of the head, processed mechanically to concentrate progenitor cells and growth factors, and then micro-injected back into thinning areas of the scalp.

How many sessions of Regenera Activa are required?

Regenera Activa is designed as a highly effective single-session treatment. Its regenerative effects develop progressively over the following months. If necessary, the procedure can typically be repeated after 12 months based on clinical evaluation.

Are there any side effects after the Rigenera treatment?

As an autologous treatment using the patient's own cells, it is exceptionally safe. Mild and temporary side effects can include slight localized redness, minor swelling, scalp tenderness, or small micro-scabs, which generally clear up within a few days.

Q: What is Regenera Activa?

Regenera Activa (or Rigenera) is an advanced medical hair regeneration treatment that utilizes autologous micrografts from the patient's own tissue to stimulate and repair hair follicles, improving density without artificial implants.

AUTOLOGOUS HAIR REGENERATION

Rigenera® (Regenera Activa®) is an innovative capillary biostimulation treatment that utilizes autologous cells to regenerate the scalp and stimulate natural hair growth in a safe and highly effective manner.

WHAT IS REGENERA ACTIVA®?

Regenera Activa® is an advanced medical hair regeneration treatment that utilizes autologous micrografts (microscopic tissue fragments harvested from the patient) to stimulate the repair and activation of hair follicles. This minimally invasive cellular biostimulation procedure strengthens, revitalizes, and awakens areas of the scalp experiencing thinning or hair loss. By harnessing the natural regenerative power of the patient’s own cells, it delivers profound results without the need for artificial components or implants.

WHAT DOES THE TREATMENT INVOLVE?

This in-office, minimally invasive procedure begins with a rigorous medical evaluation. Under local anesthesia, a few microscopic tissue samples are gently harvested from the patient, typically from the posterior region of the head (the donor area, which is genetically resistant to hair loss).

These samples are then processed using a specialized mechanical system to isolate and concentrate a powerful solution rich in progenitor cells and growth factors. Finally, this autologous regenerative solution is delivered directly into the thinning areas of the scalp via targeted micro-injections. The process stimulates hair follicles, reinforces existing hair structure, and encourages healthier growth, all while ensuring a rapid, comfortable recovery.

EXPECTED BENEFITS AND CLINICAL EFFECTS

The primary clinical outcomes of the Regenera Activa® protocol include:

Reactivating weakened and miniaturized hair follicles.
Strengthening existing hair strands, making them structurally thicker and more resilient.
Improving overall hair density and visible volume across the scalp.
Reducing progressive hair shedding and slowing down the advancement of alopecia.

Because the treatment relies entirely on autologous cell biostimulation, it actively regenerates the scalp's ecosystem, producing natural, progressive results that continue to improve over the months following the session.

POST-TREATMENT SIDE EFFECTS

Since Regenera Activa® is a minimally invasive procedure that uses exclusively autologous tissue, it is exceptionally well-tolerated, and the risk of allergic reaction is virtually zero. However, some mild, temporary side effects may occur at the treatment sites:

Transient redness or mild, localized swelling.
Scalp tenderness or minor discomfort in both the donor and recipient areas.
Small, superficial micro-scabs where the solution was injected.

These symptoms typically disappear completely within a few days. Complications are extremely rare when the procedure is performed by qualified clinical professionals.

CONTRAINDICATIONS

Regenera Activa® may not be indicated or recommended for individuals presenting with:

Active scalp infections or untreated inflammatory dermatological conditions.
Uncontrolled or decompensated autoimmune diseases.
Coagulation disorders or unmonitored anticoagulant therapies.
Active oncological pathologies.
Advanced stages of cicatricial (scarring) alopecia where viable hair follicles no longer exist.
Pregnancy or breastfeeding.

A personalized medical evaluation prior to the treatment is mandatory to verify eligibility and guarantee absolute clinical safety.

FREQUENCY AND SESSION INTERVALS

In the vast majority of cases, Regenera Activa® is performed as a single session. Because it initiates a long-term biological cascade that activates the patient's own cellular repair mechanisms, its effects develop progressively over the subsequent months. To maintain optimal results, the procedure can generally be repeated after 12 months, depending on individual clinical evolution, the degree of alopecia, and ongoing medical assessment.

RIGENERA®: THE REVOLUTION OF AUTOLOGOUS MICROGRAFTS IN HAIR REGENERATION

At Faithful Hair Clinic, we pride ourselves on being at the forefront of regenerative medicine. The Rigenera® system represents an unprecedented technological leap in the treatment of alopecia. We are not talking about a simple application of vitamins or a conventional transplant; we are talking about Autologous Cellular Biostimulation—an advanced procedure that utilizes your own progenitor cells to regenerate hair tissues in the stages of degradation.

WHAT IS RIGENERA® TECHNOLOGY?

Rigenera® is an innovative medical protocol based on harvesting autologous tissue micrografts (from the patient's own body). Through a patented mechanical process, the system disaggregates a tiny sample of scalp tissue, transforming it into a sterile liquid suspension rich in progenitor cells, mesenchymal stem cells, and growth factors.

This suspension is then infiltrated into the areas where hair is losing density, delivering a biological "repair kit" that reactivates hair follicles that were entering a dormant phase.

THE SCIENCE OF THE STROMAL VASCULAR FRACTION

The definitive difference between Rigenera® and other treatments, such as PRP (Platelet-Rich Plasma), lies in the biological complexity of the harvested material. While PRP focuses strictly on blood platelets, Rigenera® extracts vital cells directly from the connective tissue and the hair bulb.

As these cells possess a significantly higher differentiation capacity, they successfully reconstruct the hair follicle's microenvironment. In practice, this treatment acts as a high-potency "biological fertilizer" that:

Reverses Miniaturization: Fine, thinning, and translucent hairs regain their original caliber, strength, and natural color.
Increases Density: It awakens follicles that are still alive but no longer possess the cellular energy to produce a visible hair strand.
Tissue Repair: It significantly enhances the vascular health of the scalp skin, which is essential to sustain long-term hair growth.

THE PROCEDURE: SIMPLICITY AND EFFICACY IN A SINGLE SESSION

One of the greatest advantages of Rigenera® at our clinic in Porto is its absolute convenience. Unlike other therapies that require monthly commitments, Rigenera® is typically performed in a single annual session.

The Harvesting: Under localized anesthesia, three tiny tissue fragments (measuring just 2.5 mm) are gently extracted from an unnoticeable area behind the ear.
The Processing: These fragments are placed into the specialized Rigeneracons device, which separates vital cells mechanically without the addition of chemicals or enzymes.
The Application: The resulting biological concentrate is delivered via micro-injections (mesotherapy technique) directly into the areas affected by hair thinning.

The entire process takes approximately 30 to 45 minutes. Patients can leave the clinic and immediately resume their daily routines, with zero visible signs of intervention.

IDEAL CANDIDATES: WHO SHOULD CHOOSE RIGENERA®?

This protocol is particularly effective for:

Patients experiencing the early signs of hair thinning (Androgenetic Alopecia) who want to arrest its progression without immediately resorting to surgical options.
Women suffering from diffuse hair loss (female pattern baldness), where a hair transplant might not be the primary or immediate recommendation.
Patients who have already undergone a hair transplant and wish to give an extra boost of vitality to the newly implanted grafts while protecting their remaining native hair.

THE SAFETY OF THE FAITHFUL HAIR CLINIC STAMP OF QUALITY

Because it is a 100% autologous process, there is absolutely zero risk of rejection, granulomas, or allergic reactions. Rigenera® leverages your body’s very own biological pharmacy. At Faithful Hair Clinic, this procedure is performed in a controlled, premium clinical environment, ensuring absolute sterility and maximum cell viability.

We firmly believe that the future of hair medicine is not just about "filling gaps," but about preserving the youth and vitality of your cells. Rigenera® is currently the most powerful non-surgical tool available to keep your hair capital active and healthy for years to come.

FAQ (FREQUENTLY ASKED QUESTIONS)
Frequently Asked Questions about Rigenera®

Is the Rigenera® procedure painful?

No. The treatment is performed under local anesthesia administered to both the harvesting zone (behind the ear) and the target application area. Patients may experience a sensation of mild pressure during the infiltration of the progenitor cells, but the process is generally described as comfortable and significantly less invasive than a hair transplant. There is zero downtime required after the session, and no significant residual pain, allowing an immediate return to professional and daily activities.

How long do Rigenera® results last?

Results from the biostimulation with the Rigenera® system typically begin to manifest between the 2nd and 3rd month following the single session, reaching peak efficacy at the 6-month mark. Because this is a biological regeneration process, the longevity of the benefits varies depending on each patient's individual metabolism and the underlying degree of alopecia. On average, however, the improvements in hair density and strength are maintained for 12 to 18 months. An annual maintenance session is recommended to ensure the ongoing stability of your hair capital.

Does Rigenera® replace a hair transplant?

It does not replace it; rather, it complements or postpones the need for surgical intervention. Rigenera® is ideal for early to intermediate stages of alopecia, where viable hair follicles are still present and can be successfully salvaged. If an area of the scalp is completely bald (with no active follicles remaining), only a hair transplant (FUE/DHI) can repopulate that zone. However, Rigenera® is frequently used in combination with transplantation to maximize the survival rate of newly implanted grafts and protect the native hair surrounding the transplanted area.
