your hair growth?

The Kiierr 272 Premier is our most trusted, doctor-recommended laser cap, designed to help you take back control of thinning hair with confidence. It uses 272 medical grade lasers to deliver safe, powerful light therapy that targets hair follicles at the root. Just 30 minutes every other day, all from home.

Real science. Real results. Real confidence.

What makes the Kiierr 272 Premier different?

The 272 Premier is equipped with 272 medical grade 650nm laser diodes (not LEDs) to deliver consistent, even scalp coverage. It uses Kiierr’s exclusive PureLaser™ technology with a total power output of 1360 mW, offering professional strength light therapy in a comfortable at-home design.

Yes. Low-level laser therapy (LLLT) has been studied for decades and is FDA cleared to treat hair loss in both men and women. The 650nm wavelength penetrates the scalp & stimulates blood flow to the hair follicles. This helps reactivate dormant follicles, extend the growth phase & support healthier, thicker hair over time.

Most users begin noticing reduced shedding within 4 to 6 weeks. Visible regrowth typically begins around 3 to 6 months, with the most significant results appearing at 7+ months. Consistency is key. The cap is designed for 30 minute sessions every other day.

Absolutely. The same 650nm laser wavelength used in the 272 Premier has been studied in clinical trials and dermatology journals for its effectiveness in treating androgenic alopecia, general thinning and other types of hair loss. The technology is FDA cleared and widely recommended by doctors, dermatologists, and hair restoration experts.

Kiierr offers a 7 month growth guarantee. If you don’t see results and you’ve used the cap as directed, you can request a refund. See full details here. We stand behind the science and thousands of successful customer outcomes, but we also believe in risk free support for your hair journey.
