Standard 7 Month Growth Guarantee Policy

We believe in the effectiveness of our laser caps and witness the results from our customers everyday. To ensure optimal results, it is important to use the product consistently for the full 210 days as directed. If you do not experience any hair growth after 7 months (210 days) of use, you may return the laser cap for a refund, minus a 25% service fee (see below for details about the Risk Free Growth Guarantee which waives the 25% service fee).
 
To be eligible for a refund, you must register here for the growth guarantee within 45 days of receiving the device. If you do not see noticeable improvement after 7 months of use, you will email our refund department ([email protected]) to request a return. You must contact the refund department within 30 days of the 7 month mark (210-240 days). The return package must be postmarked within 10 days of the request and must include the Return Authorization number provided by the refund department. The customer is responsible for return shipping costs. Refunds do not apply to consumable items. This guarantee can only be used once per customer and applies solely to the laser cap or comb.
 
Customers also have the option to extend the Growth Guarantee from 7 to 12 months. However, they still must contact the refund department within 30 days of the 7 month mark to request an extension.
 
Important Notes:
  • Once your product ships we do not offer refunds for any reason; instead we offer the 7 Month Growth Guarantee. You must use the product for the entire 210 days before requesting to return the product. Your 210 days start the day you receive your laser cap.
  • Supplements/Consumables/Accessories are not refundable for health reasons.
  • Any disputed charges will result in not being eligible for the growth guarantee.
  • Unopened/Returned to Sender packages are charged a $50 restocking fee and will be deducted from the refund. If the package is opened or the cap is used, there is a 25% fee deducted from the return.

Risk Free Growth Guarantee Policy

At Kiierr, we are committed to your satisfaction and have established a Risk-Free Growth Guarantee to ensure that you can shop with confidence. We understand that sometimes things don't work out, and we want to make the return process as smooth as possible.
 
If you decide to return your purchase, please note that a 25% service fee will be deducted from your refund to cover processing and restocking costs. However, we offer you a unique opportunity to have this fee waived, making your purchase truly risk-free.
 
To have the 25% service fee waived, we encourage you to document your journey with the product. To do this, you would take photos or videos of your experience with the product each month (7 photos or videos in total). This documentation should clearly demonstrate your use and experience with the product. When you contact our refund department within 210-240 days of use, we will review your submitted documentation. If all requirements are met, we will waive the 25% service fee when processing your return. You must still register with the before photo within 45 days of receiving your cap here.
 
We believe this process not only helps us understand your experience better but also encourages a thoughtful and meaningful use of our products. If you document your journey and do see noticeable improvement, we offer a generous rebate for permission to use your photos or videos on our website. To submit for the rebate, please email [email protected]

Thousands of Success Stories

Real People, Real Result

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

FAQ's

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!
