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.

There have also been many other clinical trials that support the efficacy of low-level laser technology for treatment of androgenetic alopecia.
