    uses low-intensity light to stimulate cellular function and healing

    Low Level Laser Therapy (LLLT), also known as Photobiomodulation, is a treatment that uses low-intensity lasers or light-emitting diodes (LEDs) to stimulate cellular function. It is commonly used to promote hair growth in cases of alopecia, reduce inflammation, and accelerate tissue repair and healing. The therapy works by emitting specific wavelengths of light that penetrate the skin and are absorbed by cells, enhancing their energy production and promoting regeneration.
