How low-level laser therapy works
Red light in the 630 to 680 nm range is thought to boost cellular energy production in follicle cells, increase blood flow and push follicles into the growth phase.
What to look for in a laser cap
- FDA clearance for androgenetic alopecia.
- Number of laser diodes: true lasers vs LEDs, and how much of the scalp they cover.
- Session length and comfort: some caps fit under a baseball cap.
- Warranty and return policy: give it 4 to 6 months to judge.
