Before you assume pills are the only clinically backed option, there’s something worth knowing.
A clinical study published in the American Journal of Clinical Dermatology tested 655nm red light therapy for 26 weeks.
The result?
Participants using red light saw a statistically significant increase in hair density compared to the placebo group.
No pills, no hormones, and no reported serious side effects.
That matters.
Because it confirms something simple:
Follicles don’t always stop growing because they’re gone...
They stop because their growth cycle shortens and their energy drops.
Red light therapy works at that level.
It supports mitochondrial activity inside the follicle, helping restore ATP so hair can stay in the growth phase longer instead of drifting toward dormancy.
That’s exactly what Kiierr is built to do.
