Thousands of Success Stories

Karla Porter

"I started the cap treatment approximately the end of July 2021 and have been using it as directed. The after pictures were taken in March of this year. 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 the shampoo/conditioner and other supplements such as biotin." Karla Porter / Happy Kiierr Customer

Mark Shares His Kiierr Laser Cap Success Story

"After years of experimenting with several products (which almost always left me with a long price tag & short term results.) I decided to invest in the Kiier 272 Premier Model. After only 6 months of continuous use, there has been a remarkable improvement in the strength, structure and integrity of my existing hair with noticeable growth in my previous 'problem areas'.” Mark G. / Happy Kiierr Customer


Will laser therapy work for my type of hair loss?

Absolutely! The great thing about Low-Level Light Therapy (LLLT) is its versatility! Whether you are male or female, 18 or 88, from pattern baldness to hair thinning due to stress or medical conditions like including alopecia areata, hormonal imbalances, telogen effluvium and so much more.

Users of all hair textures and skin tones have seen incredible results, regardless of age. Start your journey to thicker, healthier hair today and see why so many trust Kiierr for their hair growth needs!

We have 4 laser cap options: 148 Pro, 272 Premier, 272 MD Elite, and 302 MD Ultra Flex. Choosing the right cap depends on your specific needs. For early stages of hair loss or those on a budget who are okay with slower, steadier results, the 148 Pro is ideal. If you're seeking more significant and quicker regrowth, the 272 Premier is our bestseller.

For larger head sizes or extensive coverage, the 272 MD Elite is perfect. Lastly, the 302 MD Ultra Flex offers the fastest results and superior comfort. Ideal for severe hair loss, this model also offers a soft flex fit for maximum comfort.

Results vary, but most users see noticeable improvements within 6-12 weeks. We’re so confident in our product that we offer a 7-month growth guarantee—if you don’t see results, you can return the cap!
