Capillus RX DUO
Step into the future of hair restoration with the Capillus RX DUO, engineered with 330 powerful Medical-Grade Laser diodes (290 Red Light LASER diodes at 650nm + 40 Near-Infrared diodes at 808nm) for maximum scalp coverage and effectiveness. This dual-wavelength approach stimulates follicles at different depths, helping reactivate dormant hair and support healthier, fuller growth.
330 Medical-Grade LASER Diodes
Capillus devices use LASER-only technology, to penetrate down to the hair follicle, unlike LEDs, which disperse and do not penetrate to the same depth.
The Capillus RX DUO uses 290 Red Light LASER diodes at 650nm + 40 Near-Infrared diodes at 808nm.
Benefits of 650nm Wavelength (Visible Red Light):
- Increases ATP production and cellular metabolism
- Targets Epidermis and upper dermis (skin surface and upper layers of scalp)
- Improves blood circulation near the surface, bringing more nutrients and oxygen to the hair follicles
Benefits of 808nm Wavelength (Near-Infrared Light, NIR):
- Reaches deeper follicles and stem cell niches
- Enhances microcirculation in deeper tissues, improving nutrient delivery
- Reduces inflammation and oxidative stress deeper in the scalp
Combination of 650nm + 808nm for Hair Growth:
- 650nm works on superficial layers (epidermis, upper dermis)
- 808nm works on deep layers (deep dermis, subcutaneous tissue)
- Together they stimulate both shallow and deep parts of the hair follicle and surrounding supportive tissue
6 Minutes a Day Treatment
Sessions are auto-programmed to shut off at the end of your daily 6-minute treatment, so you don't have to watch the clock.
Maximum Coverage of Scalp
LASER diodes are embedded within the interior surface of the dome, providing maximum coverage of areas susceptible to hair thinning.
Benefits of the Cross-Hatch Laser Design
- More Even Coverage: The criss-cross layout ensures overlapping light patterns, delivering consistent energy across the entire scalp.
- Enhanced Effectiveness: Closely spaced diodes improve light density, maximizing therapeutic fluence for better hair growth stimulation.
- Reduced Missed Areas: The interwoven grid pattern minimizes gaps between diodes, helping every follicle receive optimal light exposure.
- Clinically Inspired Design: Modeled after optical design principles used in FDA-cleared hair growth systems for uniform and efficient treatment.
Why Capillus?
- Capillus uses all LASERS and no LEDs.
- Capillus devices are arranged in a cross-hatch pattern to provide maximum coverage.
- Capillus Caps have a patented sensor so that the device only activate when it's on your head.
- Capillus uses the combination of 650nm Red Light LASERS and 808nm Near-Infrared diodes. The mix of both wavelengths provides an ideal treatment protocol.
- Capillus stands behind the power of our LASER therapy. Every new Capillus Cap purchased on www.capillus.com includes a 6-month Satisfaction Guarantee and a 5-year limited warranty for your peace of mind.

The Technology Behind

How to Use Capillus Caps
- Wear for just 6 minutes every day, while you work, read, watch tv, or relax.
- It works for both men and women by providing LASER therapy to the follicles on the scalp by treating hair loss and hair thinning at home or on-the-go without medication, surgery, or known adverse side-effects. If you begin treatment during the earlier stages of progression, the Capillus RX DUO can stop further hair loss and regrow the hair that has begun to thin.
- Combine with other Capillus products to accelerate results.

Are there clinical trials that support the efficacy of Capillus?
Yes. Capillus Laser devices only use clinically proven technology. In fact, the premiere laser therapy cap model from Capillus - the CapillusPro model - has been proven effective through an independently reviewed clinical trial for which results have been published in an esteemed medical journal, Dermatologic Surgery. Dermatologic Surgery is a monthly peer-reviewed journal published by American Society for Dermatologic Surgery that deals with the subject matter of dermatology.
The CapillusPro device has been clinically proven in a double-blind clinical study registered on ClinicalTrials.gov and managed by a neutral third party.* Clinical trial data indicated that low-level laser treatment of the scalp for 17 weeks with the CapillusPro device significantly improved hair counts by 51% in study participants who used the active (non-placebo) device. Subjects were able to use the device on a self-treatment, home-use basis. No side-effects of any kind were reported from clinical trial participants. The CapillusPro was proven to be a safe and effective treatment for androgenic alopecia within the appropriate stages of hair loss and skin tones as per FDA clearance.
Please note that the results mentioned above are specifically for the CapillusPro model. There have been no clinical trials to date on the other Capillus models to be able to assert an exact percent of average increase of hair.
*See details of clinical trials at ClinicalTrials.gov
There have also been many other clinical trials that support the efficacy of low-level laser technology for treatment of androgenetic alopecia.
Is Capillus good for use after hair transplant procedures?
Yes, Capillus uses safe, low-level lasers to stimulate, energize, and renew cells within the hair follicle for thicker, healthier hair. It also helps those who’ve undergone a hair transplant procedure to protect the new hair growth. Follow your transplant physician's directions for follicle support after transplant.
Are Capillus products safe for women?
Yes. Unlike some prescription medications for hair loss, Capillus LLLT (Low Level LASER Therapy) products are safe for use by women.
In fact, the convenience and effectiveness of personal LLLT products makes the Capillus products the first choice among many hair restoration surgeons who treat women suffering with thinning, shedding, or balding.
Why should I choose Capillus over other brands of LASER therapy caps?
Capillus revolutionized the hair restoration industry with the Capillus laser cap a decade ago by making professional-strength laser therapy available to hair loss patients at home. Capillus was the first laser therapy cap to be cleared by the US FDA for treatment of androgenetic alopecia. Since then, many have tried to imitate. Don't settle when it comes to your hair health.
At Capillus, we prioritize excellence above all else. Capillus caps are designed, engineered and assembled in our US-based, ISO13485-certified facility. We only use the highest quality, medical-grade lasers. Our premium laser caps are backed by our elite Physician Network, FDA clearances, our Satisfaction Guarantee, Manufacturer Warranty, and in-house, expert support. We offer choices in models making our caps affordable. We accept most credit cards and offer several payment options, including various financing options making it more affordable.
What is the difference between LASERS and LEDs for hair regrowth?
Capillus laser therapy devices use only medical grade laser diodes as a light source. What does this mean? You get the right amount of light energy exactly where you need it. Capillus uses lasers because the output penetrates deeper, better and is clinically proven to be therapeutic for their specific purpose.
Laser light does not spread as much as LEDs over the same distance, which allows lasers to penetrate tissue to a deeper level with higher concentration. For photobiomodulation therapy, the farther the light is from the target, the less intense and less effective the treatment will be.
For light therapy to be effective, it needs to reach the cells that respond well to photobiomodulation therapy.
LASER stands for Light Amplification by Stimulation of Emitted Radiation. This simply means that a source of light is amplified within a gain medium and emitted in a specific way. LASER produces a very intense beam of light which has the following properties:
- Monochromatic (meaning it consists of one wavelength)
- Coherent (meaning all parts are in phase)
- Our LASERS are gaussian to provide a wider range of coverage.
LED stands for Light-emitting Diode. And it’s pretty much just that. A diode that emits light when electricity passes through it. Often in pretty colors.
LED light can produce collimated light (with a focusing lens) but not coherent light thus they do not concentrate all their power in a coherent beam. Laser diodes by definition produce effective gaussian and coherent light output.
