Capillus is the Miami maker of laser caps worn under a sport cap, trading through Capillus, LLC and its operating company Curallux, LLC, which holds the FDA registration and sells the caps on Amazon. Its hair devices are the PRO (272 lasers), the PRO S1 (304), the Spectrum and TriSpectrum (312 each, with 40 near-infrared lasers), the MD DUO (320), the 82-laser HairBand and the 32-diode Red Light Brush; every cap runs an auto-timed 6-minute session from a separate battery pack, and every cap page but the TriSpectrum’s states 5 mW, Class 3R lasers. It also sells a face mask, an eye device, a panel, a mat, a body wrap, a full-body pod and devices for pets.

Capillus’s seven 510(k) clearances, from 2015 to 2019, name caps with 82 to 352 lasers, and the two that the current caps are listed under, K162994 and K163170, describe 650 nm lasers only. The 272-laser PRO matches the cap those filings describe. The FDA registration lists the PRO S1, Spectrum, TriSpectrum and MD DUO under two of the same clearances, but none of those filings describes a 304- or 320-laser cap or any near-infrared laser, so those four score at the floor on verification. Capillus sells the HairBand as a general wellness device and states that it is not FDA cleared, and no filing names the brush. No independent measurement of a Capillus device’s output has been published.

The 6-month satisfaction guarantee applies only to purchases on capillus.com and deducts a 25 percent service fee plus return shipping.
