All three are regenerative protocols that work toward the same goal – a healthier follicular environment. The difference is in how complete the signal is.

PRP concentrates growth factors from your own blood and delivers a strong, broad push to the follicle. It's well-studied, effective for many men, and a solid baseline. The limitation is variability: PRP quality depends on your biology – age, health, platelet concentration – which makes results inconsistent across patients.

Exosomes add a precision layer. They're microscopic signaling vesicles that carry microRNA, the regulatory intelligence that tells your cells what to do, when to do it, and how strongly to respond. Rather than just pushing the follicle, exosomes help coordinate how your scalp environment responds – more organized, more targeted. The signal is standardized and doesn't depend on your platelet quality.

Secretomes take it further. The secretome is everything stem cells produce and secrete – exosomes, growth factors, cytokines, PDRN, proteins, and extracellular matrix components working together as a complete system. Where PRP sends a push and exosomes direct the response, the secretome runs the entire operation: signal, coordination, and structural support for the follicular environment in one comprehensive payload.

The practical advantage is breadth. A secretome delivers the full range of what stem cells use to orchestrate tissue repair, rather than an isolated signal or subset of vesicles. For men who want the most complete regenerative approach available – or who have tried other protocols and want to escalate – secretomes represent the top of the ladder.

Your specialist will help you determine whether this is the right starting point or the right next step, based on where you are in your loss and what your scalp needs.

Plan for 3 initial sessions, spaced about 4 weeks apart, followed by a maintenance session every 4–6 months.

The reason it's a series and not a one-time session comes down to how hair actually grows. Each follicle moves through a multi-year cycle of growth, rest, and shedding, and at any given moment only a portion of your follicles are in the active growth phase. A single session only reaches the follicles ready to respond at that moment. By spacing sessions about 4 weeks apart, we catch follicles as they cycle into the active phase, building a cumulative effect over the series.

The first session lays the groundwork. Each one after compounds the response, strengthens the scalp environment, and recruits more follicles into active growth. Stopping after one or two sessions is the most common reason men don't see results – the underlying signal hasn't had time to build. Maintenance sessions then keep that signal active over time.

This protocol works gradually – it operates on the timeline of your hair growth cycle and can't be sped up. Most men notice less shedding within the first 4–6 weeks, which is often the earliest sign the protocol is taking hold. Visible improvements in density and coverage typically emerge between weeks 8 and 12, as follicles re-enter the active growth phase and new growth becomes apparent. Fuller, more sustained results develop over months 3 through 6 and beyond, as the cumulative effects of the secretome's multi-factor signaling compound across the treatment series.

To sustain – and sometimes improve – results, periodic maintenance sessions every 4–6 months are recommended.

Overall, this can be effective for many men, but it requires patience, consistency, and regular maintenance, with results developing gradually and lasting longest when supported by proper care.

Results hold as long as the system is maintained. The protocol doesn't stop the underlying causes of hair loss – genetics, DHT, and hormonal shifts keep working in the background. If you stop everything, in-person sessions and at-home support, gains typically start fading within 6–12 months as the underlying loss resumes.

That's why the at-home medical layer matters as much as the in-person sessions. Prescription medications don't do the same job as secretomes: finasteride and dutasteride address the hormonal drivers of hair loss by reducing DHT, while minoxidil supports growth by improving follicle performance and prolonging the growth phase. The in-person protocol stimulates follicles, reduces scalp inflammation, and rebuilds the biological environment. When you run them together, they cover both sides of the problem, which is why men on the full system hold their gains far longer than men relying on either piece alone.

At Boundless, we treat hair as a system, not a single procedure. The goal isn't just to grow hair once. It's to lock in the gains and keep fighting the drivers of loss over time. That means pairing your in-person sessions with the right supporting tools: prescriptions to address the hormonal side, medical-grade shampoos and topicals to support scalp health, and a maintenance cadence built around your specific pattern and rate of loss.

Men who follow the full system see the strongest, longest-lasting results. Men who rely on in-person sessions alone tend to see their gains erode as the underlying loss continues. Your specialist will build the right plan for where you are and what you're protecting.

No. This is one of the main reasons men choose this protocol. Secretomes are delivered through Alma TED – a device that uses ultrasound and light air pressure to drive the serum into the scalp without injections. Most men describe the sensation as a mild warm tingling or gentle pressure. There's no numbing required, no recovery, and no significant discomfort during or after the session.

Your secretomes are sourced directly from you.

During an in-person session, we collect a small sample of your hair follicles (typically around 50) from the scalp. This may involve mild discomfort as the hairs are gently pulled, but most men find it relatively tolerable and the process is quick.

Those follicles are then sent to our partner lab, where they are used to generate your personalized secretome over the course of about 60 days. This process captures the full range of biological signals your follicles naturally produce – including growth factors, proteins, and other regenerative components.

Your follicles are also preserved, which means a future treatment round can be created from the same sample without needing to repeat the collection.

Yes – especially when sourced autologously (from your own body), as we do at Boundless.

Your secretomes are derived from your own hair follicles, which means they are inherently biocompatible and avoid many of the concerns associated with donor-derived or cell-based therapies. The final product is acellular – not live cells – and consists of the signaling components your follicles naturally produce.

One important note on transparency: secretome therapies are not currently FDA-approved for hair loss or cosmetic use, and long-term large-scale data is still developing. That said, the safety profile from available research and clinical use to date is encouraging. Outcomes depend heavily on sourcing and processing quality – which is why we source from you and use a controlled lab process with pharmaceutical-grade standards.

This protocol may not be appropriate for men with active infections, inflammatory scalp conditions, autoimmune flares, active cancer or ongoing treatment, or certain systemic conditions. Your specialist will review your history to determine if it’s right for you.

Secretomes aren't something we can offer as a single, one-off session.

Your secretomes are custom-produced from your own hair follicles and developed in a partner lab over about 60 days. That process results in a fixed number of vials, so there’s no way to create or order a single-dose version on demand.

Because of that, treatment is structured as a package, with two options available depending on how many sessions you would like to commit to upfront.

This ensures you have enough material to complete a proper protocol and see meaningful results, rather than waiting two months to do a single session that’s unlikely to move the needle. You can, however, combine secretomes for hair with secretomes for skin – ask your specialist about hair & skin secretome protocols if interested.

Yes. This device has a strong safety profile when performed in a clinical setting by experienced operators.

Alma TED delivery is non-invasive and does not disrupt the surface of the scalp, which significantly reduces the risk of irritation, infection, or downtime.

Within Boundless, this is our most advanced regenerative protocol. If you prefer to receive your secretomes with microneedling, consider our protocol for that combination.

Other in-person paths include PRP via injection, which uses concentrated growth factors drawn from your own blood with targeted delivery; PRP & Alma TED, which delivers PRP needle-free via ultrasound – suited for men who want to avoid injections or want additional Alma TED Hair Care Formula support; and Exosomes + Microneedling, which delivers a standardized multi-factor biological signal through controlled micro-channels. Exosomes can also be added as a targeted boost on top of other base protocols.

Outside of regenerative protocols, common alternatives include finasteride (oral medication that blocks DHT, the hormone driving most male pattern loss), minoxidil (topical or oral; slows loss and stimulates regrowth), low-level laser therapy with at-home devices, and hair transplants for advanced loss or large bald areas.

Most men get the strongest outcome from a layered approach – the in-person protocol to deliver a comprehensive regenerative signal, supported by prescriptions and at-home routines. Your specialist will build the right combination based on your pattern, scalp condition, and goals.

Preparation is minimal. On the day of your session, arrive with clean, dry hair and avoid applying any styling products, oils, or leave-in treatments to the scalp.

Let your specialist know if you have any active scalp conditions, recent irritation, or relevant medical history before your visit.

There is no downtime, and most men return to normal activities immediately. The scalp remains fully intact, with no redness, swelling, or sensitivity expected.

For the rest of the day, avoid washing your hair or applying heavy products to allow the secretomes to absorb. You can resume normal washing and topical routines after about 24 hours.

Continue any recommended at-home products and protect your scalp from direct sun exposure. If anything feels unusual, your team can guide you.

Secretomes tend to work best when hair follicles are still present but underperforming. Men with early to moderate thinning typically see the strongest results, though meaningful improvement is still possible in more advanced cases where follicles remain. Completely bald areas are unlikely to respond.

Because your secretome is sourced from your own hair follicles, your baseline biology plays an important role. Younger, healthier follicles tend to produce a stronger and more responsive signal, which can translate into better outcomes. That said, the lab process is designed to optimize and expand that signal, so men at different ages can still benefit. Earlier intervention simply gives the protocol more to work with, and banks your current cells for use in future years.

Hormonal balance is another key factor. Sensitivity to DHT and underlying hormonal drivers of hair loss work directly against follicle recovery, which is why addressing these alongside treatment often improves results. Scalp health also matters. A scalp free of chronic inflammation or infection allows the regenerative signal to take hold more effectively.

Consistency is one of the biggest drivers of success. Completing the full treatment series and maintaining a regular cadence allows results to build over time, while sporadic treatment limits the overall impact. Lifestyle factors such as sleep, nutrition, hydration, and minimizing stressors like smoking and excessive sun exposure also influence how well your body responds.

Combining secretome therapy with medications like finasteride or minoxidil typically leads to stronger, longer-lasting outcomes, since each approach targets a different part of the problem. Your specialist will tailor the right combination based on your starting point and goals.

Secretomes are the most advanced regenerative tool we offer – a high-density, full-spectrum collection of powerful biological signals your body uses to repair and rebuild tissue. They include growth factors, exosomes, PDRN, proteins, cytokines, and signaling molecules that actively direct how cells regenerate, function, and improve over time.

These signals are produced by stem cells. Think of stem cells as the body’s master repair crew – the secretome is the full toolkit they deploy to get the job done. Instead of introducing the cells themselves, we isolate and deliver that entire signal system directly.

At Boundless, your secretome is sourced from your own hair follicles, creating a personalized, high-impact regenerative signal. Applied to the scalp after microneedling or with Alma TED, it delivers a deeper, broader, and more coordinated repair response – helping improve not just hair growth, but the entire follicle environment for stronger, more consistent results.
