Thinning hair doesn’t fix itself but Kiierr gives your follicles the wake up call they’ve been waiting for.

The 272 Premier Laser Cap uses laser therapy, a medical grade technology backed by real clinical research & trusted by doctors worldwide. The lasers deliver precise red light energy deep into your scalp, boosting blood flow, reactivating weak follicles & restoring the natural growth cycle.

No drugs. No surgeries. No side effects. Just real results.

And the best part? If it doesn’t work, we have a 100% refund option.

Hair growth should be effortless and with Kiierr, it is.

Just wear the cap for 30 minutes every other day. That’s it.
It runs on a rechargeable battery, so you can move, work, scroll, or relax while the lasers do their job. There’s no heat, no discomfort, and no interruptions to your routine.

Everything you need to grow with confidence:

  • Laser Cap with 272 medical grade lasers (650nm wavelength, 1360 mW total power output)

  • Ball cap, rechargeable battery, wall charger & carrying case

  • Free mystery gift included with your order (limited time offer)

Sizing Note: Laser cap fits heads up to 23.5 inches in circumference. The cap doesn’t need to be snug, it just needs to rest gently on the scalp. The light penetrates evenly, even if it sits higher on the head.

Hair regrowth takes time, but the results are worth it.

  • Most users see less shedding within the first 60 days
  • By months 3–4, hair often looks thicker and fuller
  • At 5+ months, many see visible regrowth in thinning areas

Consistency is everything. This isn’t a quick fix. It’s a lon term solution backed by science & trusted by over 125k customers.

Growth Guarantee: Use your Kiierr cap consistently for 7 Months. If you don’t see results, return it for a refund.
There’s a 25% fee, but it’s waived if you take simple monthly progress photos. Registration with a before photo is required within 45 days of receiving the cap. Read Full Return Policy

Hard to Believe? See for Yourself.

It’s a worthwhile investment!
I started using my Kiierr cap almost 4 years ago at 63. After the first 6 months or so, I noticed that there was less hair caught by my shower drain strainer than in the past. My temples and the thinning hair on my crown have filled in.

Frank L

My hair is thicker than it’s ever been!
I suffer from hormone-related hair loss. It was devastating to see my hair become thinner & thinner. I have been using Kiierr for 10 months now. At first I was skeptical (was this too good to be true?), but I was astounded when I started seeing growth after 6 weeks!

Denise C

My hair is a lot thicker!
Thicker hair on my crown has been the most noticeable change since starting with Kiierr. Over the last several months, my hair has visibly thickened, especially in areas that were previously thinning.

My hair is thicker and fuller!
After contracting COVID, I experienced severe hair loss. I tried the Kiierr Laser Cap and after 5-6 weeks, new hair began growing on my bald spots. By two months, my hair became thicker and fuller. After three and a half months, I was thrilled with the results and highly recommend!

Marsha W

Nothing worked until Kiierr!
After spending 10 years trying other hair growth products, I heard about the success of laser therapy after researching. As you can see, during the 3 year process of using the Kiierr Hat, I could see remarkable results after only 6 months.

James R

The Kiierr Cap really helped!
I've always had thin hair in the crown but 3 months after having Covid, my hair started coming out in handfuls. The Kiierr cap was what helped along with Kiierr’s shampoo, conditioner and biotin.

It’s a game-changer for my hair loss
Easy to use cap which I have been using for about 5 years now, every other day. My hair strands have become thicker & have less shedding. I would definitely recommend the Kiierr cap, especially due to the scientific backup.

Vincent R

Highly recommend all Kiierr products!
The laser cap definitely helped regrow hair over the balding spot on the crown of my head and on my thinning/receding front hairline! I also use the Kiierr shampoo, conditioner and vitamins. I highly recommend all Kiierr products!

Amazing for male pattern baldness!
I highly recommend this product to anyone with hair loss. Male pattern baldness started in my 20s with a receding hairline and thinning crown. I have seen awesome results with red light therapy and it was worth every penny.

Why Do You Need a Laser Cap?

Why Do You Need
 a Laser Cap?

Hair loss doesn’t fix itself. Shampoos, topicals & cheap gadgets can’t revive dead or weakened follicles. That’s where laser therapy comes in. The Kiierr 272 Premier uses medical grade laser light to wake up struggling follicles & restore their natural growth cycle. This isn’t about vanity. It’s about catching hair loss before it’s too late and choosing a solution that actually works.

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.
