Capillus PRO Laser Cap (272 lasers)
Capillus
Laser-only cap with 272 laser diodes at 650 nm, worn under a baseball cap; Capillus says 6 minutes a day. Price: $1,699, checked Oct 3, 2026; Capillus lists a 6-month satisfaction guarantee, a 3-year limited warranty and HSA/FSA payment. Regulatory: FDA-cleared (K163170) for over-the-counter use, cleared as the Capillus '272 Pro' (the product page calls it Capillus PRO and doesn't print the K-number), to treat androgenetic alopecia (pattern hair loss) in men (Norwood-Hamilton IIa-V) and women (Ludwig-Savin I-1 to II-2 or frontal) with Fitzpatrick skin types I-IV; not cleared for other types of hair loss. The 6-minute daily routine differs from the 30 minutes every other day used in the trial summarized in Capillus's earlier 510(k). Capillus's Spectrum and TriSpectrum caps, which add near-infrared wavelengths, have no 510(k) under those names. Evidence grade: B (for the device category, androgenetic alopecia only; not graded for this specific device or for other types of hair loss). A 2025 meta-analysis of 38 studies (about 2,930 people with androgenetic alopecia) found a larger increase in hair density with light therapy devices than with placebo or sham after 4-26 weeks, but results varied widely between trials and many trials were small or funded by device makers. Goals: hair. Directory: Red light > Laser & LED hair caps.
