If you’ve been researching hair restoration options in New York, you’ve probably come across exosome therapy — and you may have noticed it’s often described differently from clinic to clinic. At New York Hair Transplant, we use a specific, physician-developed protocol: an AMP Biologics-derived exosome solution delivered through what we call the Dr. Roth Method, combining microneedling and ultrasound technology to get more of the treatment where it needs to go.
What Exosomes Actually Do
Exosomes are microscopic extracellular vesicles that act as cellular messengers. They carry growth factors, signaling proteins, and genetic material that help coordinate tissue repair and regeneration throughout the body. When applied to the scalp, they support the activation of hair follicles, help improve the surrounding scalp environment, and encourage stronger hair growth in follicles that are still active.
The exosomes we use are derived through AMP Biologics and processed under strict quality controls in FDA-registered laboratories. Because they’re cell-free products, there’s no live-cell content — which means a very low risk of immune reaction and a strong overall safety profile.
The Dr. Roth Method: Why Delivery Matters as Much as the Product
A high-quality exosome solution is only half the equation. Getting it to actually penetrate the scalp and reach the follicles is the other half — and that’s where the Dr. Roth Method comes in. Developed by Dr. Roth, this protocol combines two delivery technologies in the same session:
- Microneedling creates controlled microchannels in the scalp, which stimulates collagen production and opens a direct path for the exosome solution to be absorbed rather than sitting on the surface.
- Ultrasound delivery is then used to help drive the exosomes deeper into scalp tissue, improving distribution across the treatment area.
Together, these two steps are designed to meaningfully improve how much of the treatment actually reaches the follicles, compared to injection or topical application alone.
What a Session Looks Like
A typical exosome session at NYHT takes about an hour, and includes:
- Scalp preparation — the treatment area is cleansed, and a topical numbing cream may be applied for comfort.
- Microneedling — controlled microchannels are created across the treatment area.
- Exosome application — the AMP Biologics-derived solution is applied and introduced through the microchannels.
- Ultrasound delivery — ultrasound technology enhances penetration and even distribution across the scalp.
Who Tends to Be a Good Candidate
Exosome therapy with the Dr. Roth Method is often recommended for patients who:
- Have moderate to advanced pattern hair loss with follicles that are still active
- Have plateaued with PRP and want a higher concentration of growth factors
- Are recovering from a recent hair transplant and want to support healing and graft survival
- Are dealing with postpartum, stress-related, or seasonal shedding that hasn’t responded to other treatments
- Want meaningful results from fewer sessions than a typical PRP series
It’s worth noting that exosomes work on follicles that are still present and active — areas that are completely bald, with no remaining follicles, generally require a hair transplant instead.
What to Expect Afterward
Most patients see initial signs of reduced shedding within 2–4 weeks, with visible improvements in density and thickness developing over the following 3–9 months as the growth cycle progresses. A typical protocol involves 1–3 initial sessions spaced 8–12 weeks apart, followed by maintenance roughly once every 9–12 months.
Combining Exosomes with Other Treatments
Exosome therapy pairs well with both Manual FUE and ARTAS® iX Robotic FUE — many transplant patients add a session or two in the first 3–6 months post-procedure to help accelerate healing, reduce shock loss, and support graft survival.
Ready to See If Exosome Therapy Is Right for You?
Every patient starts with a free consultation and scalp analysis, so we can walk through your specific hair loss pattern and whether the Dr. Roth Method, PRP, a transplant, or a combined approach is the best fit. We’re currently offering up to $2,500 off eligible procedures, including a limited-time summer exosome package.
