The Biomechanics Behind The Results
Light Penetration
Targeted red light (630–660nm) waves penetrate the skin and are absorbed by key cellular structures within hair follicle cells.
Cellular Activation
Red light waves interact with cytochrome c oxidase in the mitochondria, helping boost cellular energy (ATP) and support normal cell function.
Follicle Stimulation
With more cellular energy and improved microcirculation, hair follicles receive more energy and nutrients, helping extend the growth phase, increase thickness and reduce hair loss.

Frequently asked questions
How often should I use the cap?
As a rule of thumb, we recommend 5 minutes a day. But this is flexible, users can do 10 minutes a day or 10 minutes every other day. Optimal usage frequency will vary with different individuals so we recommend experimenting with different routines to see what produces best results and is most convenient / sustainable.
How does red light therapy work for hair growth?
Red light therapy uses specific wavelengths of light to stimulate cellular activity in the scalp. This helps improve energy production in hair follicle cells and supports a healthier hair growth cycle.
Is this clinically proven?
Red light therapy has been studied in multiple clinical settings and is widely used as a non-invasive approach to support hair growth. Individual results may vary.
Does this regrow hair or just prevent loss?
It can help support both - reducing shedding and improving thickness -depending on your hair condition and consistency of use.
Does it cause any side effects?
Side effects are rare. Some users may experience mild warmth or temporary scalp sensitivity.
