Is the black laser helmet real or fake?

It's true. I Black laser helmet is approved by the US Food and Drug Administration (FDA). This helmet is based on "low-energy laser therapy", combined with self-developed automatic energy stabilization system, precise lighting in different areas and other patented technologies, and adopts medical-grade soft laser (650nm, 5mV), which can penetrate the root of hair follicle 3-5mm below the scalp, release various growth elements and accelerate hair follicle development. At the same time, the thermal effect of laser can also accelerate blood circulation, revitalize hair follicles and promote hair regeneration.
