Our helmet uses Low-Level Laser Therapy (LLLT), also known as photobiomodulation. The safe, cool laser light energy is absorbed by the hair follicles, which stimulates cellular activity, increases blood flow and leads to key nutrients and oxygen being delivered to the hair follicle. This process helps to revitalize weakened follicles, encouraging them to transition from a resting phase back into a growth phase, leading to thicker, fuller, and more healthier hair.
