The Capillus Protocol
Turning Science Into Simple, Effective Guidance
Our studies revealed a simple truth: results increase dramatically when treatments are structured, consistent, and tailored to the user. That’s why we created the Capillus Protocol, a clear, step-by-step system that translates our scientific findings into everyday use. With the Capillus Protocol, you can follow the same evidence-based approach, ensuring stronger outcomes and a more reliable path to results.

What is red light therapy and how does it work?
Red light therapy uses safe, low-level light to stimulate your cells, improving circulation, boosting collagen, reducing inflammation, and supporting natural repair.
Is red light therapy safe?
Yes. Capillus devices are FDA-cleared, non-invasive, and safe for regular use at home.
Hair Regrowth Caps
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.
How often should I use my Capillus cap?
Treatment is typically just 6 minutes per day, depending on the model.
Can I use the caps with other hair treatments?
Yes. Capillus caps are safe to use alongside topical treatments, hair supplements, and procedures recommended by your doctor.
What makes Capillus caps different from other devices?
Capillus caps use 100% medical-grade lasers (not LEDs) to penetrate deeper into the scalp and directly stimulate dormant follicles.
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.
Why should I choose Capillus over other brands of laser therapy?
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)
- Collimated (meaning all parts travel in one and same direction)
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 to provide a wider range of coverage and coherent light output.
Key Differences Between the Capillus Caps?
While each of the Capillus caps has numerous similar features, the primary difference between them is a difference in scalp coverage, as well as total energy output. What does more lasers mean? Density of lasers translates to density of results. With more lasers per inch you will see results over more areas, for even more results noticeable faster.
Skin Health Devices
What does the Capillus Face Mask help with?
The mask targets fine lines, wrinkles, uneven tone, and dullness by stimulating collagen and improving skin texture.
How long do treatments take with the mask?
Sessions are short, comfortable, and hands-free — typically around 10–15 minutes.
Aches & Recovery
What is the Capillus Healing Pod used for?
The Healing Pod delivers full-body red light therapy to reduce inflammation, support muscle recovery, and promote relaxation.
Can red light therapy help with joint pain?
Yes, red light therapy has been shown to reduce stiffness and discomfort associated with arthritis and other inflammatory conditions.
Bundles & Savings
Why should I buy a bundle instead of one device?
Bundles combine multiple devices for hair, skin, and body, giving you complete care and additional savings.
Do the bundles deliver the same results as buying devices separately?
Yes, each device in the bundle works exactly the same as if purchased individually. The benefit of a bundle is that you can address multiple concerns (hair, skin, and body) at once while saving more.
