Kiierr laser cap

Kiierr Laser Cap

Kiierr, the laser-based hair growth caps manufacturer, received FDA clearance in 2018 and is the youngest competitor. They have two laser caps, the budget-friendly Kiierr 148 Pro and the professional-grade Kiierr 272 Premier. 

Time to dig into the kiierr laser caps specifications, pricing, payment options, warranty, and money-back guarantee.


The Caps

Consisting of 148 laser diodes, the Kiierr 148 Pro caps generate 740 Mw power output at 650 nm wavelength. The 148 Pro is ideal for those looking for an affordable option. However, it might not be the best choice for candidates suffering from medium balding.  To get optimum results, one must use the caps thrice a week for 30 minutes. The caps include a baseball hat with the lasers, a headband to secure the cap, a wall charger power plug, a portable power pack, a USB cord, and a user manual. Both the caps have a circumference of approximately 23.5", meaning they will fit most people.  The caps come with an automatic shut-off feature. So you can operate them hands-free.  Both the caps come with a standard 2-year manufacturer warranty.

All Kiierr laser caps come with a standard 2-year warranty. You can buy an extended warranty with the product separately and then register your product with the warranty here. To know about warranty-related policies for products purchased from other platforms, I suggest you talk to their customer support first. 

Money-back Guarantee 

The 7-month money-back guarantee applies to the Kiierr laser caps. I suggest you read the refund policy in detail. It’s crucial to register your product after purchase to be eligible for the warranty and the money-back guarantee. Kiierr ships internationally, but I am not sure whether the refund policy applies to residents outside the US. 

Kiierr laser caps are ideal for male pattern baldness within the range of IIa to V and, for female pattern baldness, the range is I to II. The caps are recommended for Fitzpatrick skin types I to IV. If you have baldness beyond the mentioned range or skin type beyond the mentioned classification, I suggest you talk to their sales team before buying the product.
