Seta Scalp & Hair Therapy Comb

The Growth Wavelength

10–20 minutes | 3–5 x per week

The gold standard in scalp therapy ~ and the most extensively studied wavelength for hair health.

Red light penetrates deeper than any other visible wavelength, reaching the base of the hair follicle where growth is initiated and sustained.

At this level, it stimulates cellular energy production, increases blood flow to the follicle, and delivers the oxygen and nutrients that hair needs to grow stronger, thicker, and more resilient over time.

The follicle, like any living structure, responds to stimulation. Red light is that signal ~ consistent, precise, and cumulative. With regular use, dormant follicles are encouraged back into their active growth phase.

Shedding slows. Density improves. Hair that was thinning begins to recover its strength from the root up.

This is not a temporary fix. It is a fundamental shift in scalp health ~ one that compounds with every session.

Best for: hair thinning, hair loss, follicle stimulation, scalp circulation, hair density and strength
