Lasers vs. LLLT for Hair Loss

Vanessa Gibbs’ 13 August post explains the distinction between low-level laser light therapy (LLLT) and LED devices while promoting Blueprint’s 302 Laser Cap. The page says the cap uses 302 laser diodes at 650 nm and that Bryan Johnson wears it for 6 minutes each day after his hair-serum routine. It recommends laser diodes, a 630–670 nm wavelength, broad coverage, and sessions of 6 minutes or less. The article repeats claims that LLLT can produce visible hair results in about 4 months and that laser diodes deliver 2.5 times more on-target intensity than LEDs. It does not report a randomized trial of the Blueprint cap, a comparator device, participant count, standardized hair counts, or an adverse-event table. The product page is therefore a marketing explainer and a protocol-adjacent drop, not a self-experiment report. The post cites FDA clearance for the technology in general, but clearance does not establish that this specific cap improves hair growth beyond a comparator. Johnson’s own use is described as routine behavior, with no before-and-after data in the article. The factual update is the device specification and the 6-minute daily use instruction. Claims about regrowth remain product claims until a device-specific human study with a defined endpoint is available.
