What is red light therapy?
Red light therapy is a non-invasive treatment that uses visible red wavelengths (typically 620–750nm) to stimulate cellular energy production and enhance tissue repair.
In the context of hair growth, it works by improving circulation, reducing inflammation, and energizing hair follicle cells to extend the growth phase.
Red light therapy is one of the most promising modalities for non-surgical hair restoration and is supported by both clinical studies and anecdotal success stories.
