Very easy to incorporate into your daily routine.

"This is my second model Capillus, now a customer for six years. Had a great experience with my first now outdated. Product support and service takes some patients and persistent but once in contact with a live agent I was made completely satisfied every time. Isis and Morgan, both credits to the organization demonstrating a knowledgeable, caring and professional demeanor. Currently enjoying the benefits of the Capillus Spectrum. From my experience, a solid product back by a company who supports the client during and after the sale."

Noticeable Results

"I’ve been using the Capillus Spectrum consistently for a few months, and it’s been a solid addition to my routine. . I’ve noticed less shedding and my hair feels a bit fuller overall. It’s not an overnight fix, but with consistency, it definitely delivers noticeable results."

— Alex M. (5/5)

Quick results. . . very impressed.

"I've used different LLLT devices in the past with minimal results (then a plateau). I also wasn't on medication then. I've been on medication (dutasteride and oral minoxidil) for two years before plateauing. I decided to add LLLT back into my routine. I wanted to try a 6 minute protocol. I am not sure if it is the 6 minute daily dose or the 808nm lasers or both, but I have seen incredible improvement after a just a month. I actually saw changes after two weeks. I can feel my scalp getting comfortably warm after the 4 minute mark. I honestly thought I'd be disappointed and return, but I'm very happy and it is early on. It's so easy as I use it while I brush and floss. . . then I'm done for the day. I am looking forward to the coming months. It also seems like a good quality device and the charging dock is convenient."

— Gregory W. (5/5)

excellent customer care

"I called a few times trying to cancel my purchase, just about to flight overseas an email stating that it was gonna be a delayed for my package. I called, talked to someone on the phone and she did it!. . . I got all my packages on time. Thank you so much, idk her name but she made it possible.

Q&A

FAQs

Have a question ?

Please read our frequently asked questions to find out more.

We are here to help.

How does the Capillus Spectrum work?

The Capillus Spectrum uses advanced red and infrared laser therapy to stimulate hair follicles. The 808nm infrared lasers penetrate deeper into the scalp, while the 650nm red lasers improve blood circulation, encouraging healthier, thicker hair growth.

How often do I need to use the Capillus Spectrum?

Just 6 minutes a day is all you need to see results. Consistent use is key to achieving optimal hair regrowth.

What makes the Capillus Spectrum different from other laser caps?

The Capillus Spectrum features 808nm infrared lasers, setting a new standard in the industry by penetrating deeper into the scalp than devices that only use 650nm lasers. This unique technology delivers faster, more effective hair regrowth.

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.
