How Does Kiierr Laser Cap Work?
The cap uses red light laser diodes to stimulate hair follicles.
Mechanism of Action:

- Increases blood circulation
- Boosts cellular energy (ATP production)
- Reactivates dormant hair follicles
This process is called photobiomodulation.
Scientific research suggests that LLLT can increase hair density and thickness when used consistently. (PMC)
