What is Capillus?
Capillus is a trusted manufacturer of hair loss solutions. It offers four models equipped to provide low-level laser therapy in the comfort of your home.
Each laser cap provides high-quality laser therapy through the use of medical-grade laser diodes. With treatment sessions of six minutes, it's a convenient, easy-to-use solution that may help with hair loss and hair thinning.
Low-level light therapy (LLLT) has been evaluated primarily for treating hair loss in male and female patients. Clinical studies have indicated that LLLT is generally safe and potentially effective in increasing hair density and caliber and reducing thinning hair.
Promote hair health with professional-grade coverage for your scalp and achieve results with 6-minute sessions every day.
As a non-surgical treatment for hair loss, LLLT uses a red light wavelength of 650 nm to stimulate the dormant hair follicle and begin hair regrowth. Harnessing this technology, the makers of Capillus provide four models that differ primarily on the number of diodes.
Capillus laser caps and the number of laser diodes:
Model | Diodes |
Capillus Spectrum | Utilizes 312 laser diodes and dual frequencies to supposedly promote deep penetration of the laser therapy |
Capillus Pro S1 | Utilizes 302 medical-grade laser diodes |
Capillus Pro | Utilizes 272 medical-grade laser diodes |
Capillus One | Utilizes 112 medical-grade laser diodes |
One additional benefit seen with the Capillus Spectrum and Capillus Pro S1 is the availability of Bluetooth connectivity. This allows pairing with the Capillus S1 app that allows progress visualization, treatment tracking, and treatment reminders.
Finally, each Capillus laser cap is FDA-cleared and meets the specifications for safety and effectiveness allowing you to sleep easy knowing you have a quality product.

Capillus effectiveness and safety
Low-level light therapy (LLLT) has been evaluated by many different clinical studies and has shown promising results in improving hair growth in androgenic alopecia (male/female pattern hair loss). Additionally, LLT may stimulate healthy hair growth in other conditions such as alopecia areata, telogen effluvium, and chemotherapy-induced hair loss. It activates hair follicles to undergo active hair growth through many different biological processes within the cells responsible for the production of hair.
LLLT reduces the transition of hair follicles from the anagen (active growth phase) to the catagen (phase of regression and reduced production of hair). This increases the number of actively growing hair strands which improves the density of hair. Moreover, keeping hair in the anagen stage may also increase the caliber of the hair shafts for improved scalp coverage.
Finally, LLLT for the scalp may help to reduce scalp inflammation and irritation resulting in a healthier-looking scalp and hair.
While some clinical studies show the benefits of LLLT, individual results may vary and the use of these devices does not guarantee the regrowth of hair or the prevention of future hair loss.
Overall, LLLT is generally regarded as safe for use in hair regrowth devices. The side effects attributed to LLLT tend to be mild. To reduce the risk of side effects, it is recommended that all manufacturer recommendations be followed and that treatment times not exceed the treatment recommendations of the manufacturer.
User experience and performance
Trustpilot rating | Amazon rating | Official website |
4.4 ⭐⭐⭐⭐ | 3.7 ⭐⭐⭐ | 4.75 ⭐⭐⭐⭐ (Average of all devices) |
The reviews from customers are generally impressed with the results provided by the Capillus laser caps. However, like all products, individual results vary, and some have not noticed a benefit from their use.
As expected, those who achieved visible hair growth, generally felt the device was worth the higher price tag. However, those customers without adequate results, felt the device was overpriced and not worth the money.
Some users do not feel the hat fits securely enough to perform daily activities, but with the short treatment time (six minutes) many do not feel it interferes dramatically with their lives.
What people liked
- Short, six-minute treatment sessions
- Noticeable hair regrowth (individual results may vary)
- Thicker hair with improved hair density
- Reduced hair loss
What people didn't like
- Higher diode count devices are too expensive
- The hat does not fit securely on the head
- Results are slow and may take up to seven months or more
Expert opinion
Dr. Anastasia Therianou, a consultant dermatologist in the UK, promotes the use of LLLT for hair loss on her website and writes about its potential benefits.
Dr. Marc Avram, a hair transplant specialist and cosmetic dermatologist in New York City, recommends using LLLT devices, in addition to other treatment methods, to stimulate hair regrowth in his patients.
Tips and tricks for best results
To achieve the best results, it is important to use the device consistently. Identifying a time in the day to incorporate the treatment session is the best way to ensure you make time daily for your treatment.
Devices with short treatment durations and portability allow the sessions to be incorporated into your daily routine with minimal disruption.
Before starting the therapy, it is advised to discuss the use of LLLT with a healthcare provider. They may provide specific recommendations as well as determine if medications or other treatments are needed to increase your hair growth potential.
Remain patient with your treatment as it can take three to six months to notice results. It is important not to increase treatment times or frequencies in attempts to obtain faster results as this may cause side effects.

Common mistakes to avoid
For the best results, it is important to avoid these commonly made mistakes.
- Quitting therapy too soon. Results can take three to six months to become visible and thus patience is key to adequate results.
- Using for inappropriate conditions. Laser caps may effectively improve hair regrowth in androgenetic alopecia, but in other conditions, the results are still inconclusive.
- Exceeding recommended treatment durations or frequencies. To minimize the risk of side effects, it is recommended users stick to the manufacturer’s treatment recommendations.

Final verdict: is Capillus worth it?
Capillus manufactures high-quality laser caps that allow individuals of all budgets to have innovative low-level light therapy equipment at the convenience of their homes.
While the higher-end models offer additional features, it is my opinion that the Capillus Pro offers the best value for the money.
This device provides an additional non-surgical and non-pharmacologic treatment that is best suited for patients with androgenic alopecia (male/female pattern baldness).
If you are considering one of these devices, talk with your healthcare provider to ensure the device is appropriate for you to use and if any additional treatments should be combined with this therapy.
FAQ
Does the Capillus cap actually work?
Yes. Scientific studies have reported low-level light therapy to be effective in increasing the density and caliber of hair when used for androgenic alopecia. While results may vary between individuals, the Capillus devices have been suggested to provide visible hair regrowth with three to seven months of consistent use.
What are the side effects of Capillus?
Low-level light therapy is generally viewed as safe with minimal risk of side effects. The side effects that might be experienced are mild scalp irritation, scalp itchiness, slight redness, and an initial period of hair shedding. While generally regarded as safe, it is important to discuss with your healthcare professional before starting any new treatment.
