Capillus RX DUO: The Next Generation of Low-Level Laser Therapy
Six minutes a day, at home, to hold and thicken the hair you have. What the dual-wavelength cap does, who it is for, and where it fits alongside a transplant.
Key takeaways
- Low-level laser therapy is an FDA-cleared, non-invasive option for early thinning. The RX DUO is its newest medical-grade form.
- Dual wavelengths (650 nm red plus 808 nm near-infrared) and 330 laser diodes reach both surface follicles and the tissue beneath.
- One 6-minute session a day, app-tracked, and backed by a Capillus limited manufacturer warranty.
- Physician-exclusive: it is not sold over the counter. Best for maintaining and thickening, not for restoring bald areas.
For patients in the early stages of thinning, low-level laser therapy has long been a proven, non-invasive option. The technology has now taken a real step forward. Advanced Hair Restoration® offers the Capillus RX DUO, a medical-grade device available only through physicians, and the most capable home laser cap we have seen.
Dual-wavelength technology
Older LLLT devices used a single wavelength. The RX DUO combines 650 nm red laser light with 808 nm near-infrared, so it stimulates the surface-level follicles and the deeper supporting tissue at the same time. Its 330 medical-grade laser diodes spread that light evenly across the entire scalp, so dormant follicles get a uniform, concentrated dose rather than patchy coverage.

Treatment that fits your day
Treating hair loss should not disrupt your life. The RX DUO needs one six-minute session a day, worn while you read, work or relax.
- Battery. Up to six full treatments on a single charge.
- Charging. A compact docking station that fits on a nightstand.
- App. Bluetooth connection to the Capillus app to log sessions, check battery and track regrowth with progress selfies.
Quality and assurance
The RX DUO is manufactured, assembled and serviced in the USA and is backed by a Capillus limited manufacturer warranty. Because laser therapy takes patience, ask your Advanced Hair Restoration office about the current warranty term and return terms when you order. Whether the goal is to slow shedding or improve overall density, the device is designed to deliver visible results across gender, age and hair type.
Free consultation
Is a laser cap right for you?
It depends on where you are in your hair loss. An Advanced Hair Restoration® expert tells you whether LLLT alone, a transplant, or both belongs in your plan, and can secure your RX DUO at the visit. Consultations are free.
Where it fits
LLLT is a maintenance and thickening tool. It supports the follicles you still have and pairs well with medication, and many of our patients use it after a transplant to protect the native hair around the new growth. It does not restore hair where follicles are gone. For that, Advanced FUE™ remains the only permanent option. Read more in How to Stop Hair Loss and Promote Hair Growth.
Physician-exclusive
Because the RX DUO runs at maximum power with medical-grade components, it is not sold over the counter. It is available only through certified medical providers, including every Advanced Hair Restoration® office.
Questions patients ask
Laser cap questions
Does low-level laser therapy actually work?
LLLT is FDA-cleared for hair loss and is best at maintaining hair and improving density in thinning areas. Results vary and depend on consistent daily use. It does not regrow a bald area.
Can I use the RX DUO after a hair transplant?
Yes, once your physician clears the recipient area, usually a few weeks after the procedure. Many patients use it to protect native hair and support the transplanted follicles as they grow in.
How long until I see results?
Plan on several months of daily use before density changes are visible. The app's progress photos make the change easier to see.
Is it safe?
Low-level laser is non-thermal and non-invasive. Sessions are painless, and the device is cleared for home use.
