Glossary Laser Hair Therapy

uses low-level lasers to stimulate hair growth and reduce loss

Laser Hair Therapy, also known as Low-Level Laser Therapy (LLLT), is a non-invasive treatment that uses low-level lasers or light-emitting diodes (LEDs) to stimulate hair follicles, promoting hair growth and reducing hair loss. This therapy is often used to treat conditions like androgenetic alopecia and is believed to improve cellular function and blood flow in the scalp, thereby enhancing hair density and thickness.
