Laser diodes, not a blanket of glow.
Both lasers and LEDs can emit red light. The physical delivery differs: laser diodes create narrow, directional beams, while LEDs generally spread non-coherent light more widely. MARS uses 272 laser diodes across the cap.
That is an engineering choice, not proof that every laser device outperforms every LED device.
Research, with the fine print in full view.
Red-light devices around 630–660 nm have been studied in randomized, sham-controlled trials for pattern hair loss. In one 24-week trial, a different helmet used 224 laser diodes at 660 ± 10 nm and 5 mW per diode and reported a greater increase in hair density than sham.
That protocol and those findings belong to the study device, not to MARS. Geometry, dose, session length and safety documentation all matter. A systematic review also found meaningful variation between products and study designs.
