What is LED therapy?
LED therapy uses light-emitting diodes to deliver low-energy light to the skin or scalp for therapeutic benefits such as inflammation reduction and collagen production.
Unlike laser devices, LEDs are non-coherent and less focused, allowing for broader treatment coverage without heat or discomfort.
Red and near-infrared LED therapy is often used to support hair growth by improving blood flow, cellular metabolism, and follicle cycling in thinning areas.
