The Science Behind Red Light Therapy

Red light therapy — also known as photobiomodulation — has been studied for decades. The core principle is simple: specific wavelengths of light penetrate the skin and stimulate cellular activity at a biological level.

Why 660nm and 850nm?

These two wavelengths are the most researched in the context of hair regrowth:

660nm — Red Light
Absorbed directly by the cells in the hair follicle. Stimulates mitochondrial activity, increases ATP production, and promotes cellular repair. This is what wakes up dormant follicles.

850nm — Near-Infrared Light
Penetrates deeper into the scalp tissue. Reduces inflammation, improves blood circulation, and creates a healthier environment for sustained hair growth.

How It Affects Hair Growth

Hair grows in cycles — anagen (growth), catagen (transition), and telogen (resting). Hair loss occurs when follicles spend too long in the resting phase or stop responding entirely.

Red light therapy has been shown to shift follicles back into the active growth phase by energising the cells responsible for hair production.

What This Means For You

No chemicals entering your body. No needles. No clinic appointments. Just consistent, targeted light — delivered to your scalp in 10 minutes a day.
