Ever wonder what goes into creating a Kiierr laser cap? You’re not just buying a device — you’re investing in medical-grade technology, clinical precision, and real human care. Here’s a behind-the-scenes look at how we ensure every cap meets the highest standards before it reaches your hands.
At the heart of every Kiierr 272 Premiere Cap are the same laser diodes used in FDA-cleared clinical equipment. These aren’t generic components — they’re carefully selected to deliver the optimal wavelength (650nm red light) proven to support hair regrowth. We work directly with trusted suppliers to ensure each diode meets the performance standards needed for effective and safe use at home.
All Kiierr caps are FDA-cleared for both men and women — a key distinction that sets us apart. We follow strict manufacturing protocols to ensure each cap complies with U.S. medical device regulations. From the circuitry to the outer shell, every part is chosen with quality, durability, and safety in mind. You can feel confident knowing your cap meets the same regulatory standards trusted by clinics.
Every Kiierr laser cap is assembled individually — not pulled from an assembly line at random. Our technicians carefully position each laser diode for optimal coverage, test the internal systems, and ensure proper function of the battery and sensor mechanisms. This attention to detail helps ensure consistent performance and a smooth experience from your very first treatment.
Before we ship anything, each unit goes through a full functionality check. We test the diode output, battery charging cycle, and safety sensors that ensure the cap only operates when it’s properly placed on the head. This isn’t a random sample — we test every cap. It’s our way of making sure you never receive a defective product.
We build Kiierr caps to last, and we stand behind them with a full 2-year warranty and our industry-leading 7-month Growth Guarantee. You’re not just purchasing a hair regrowth device — you’re investing in something tested, trusted, and fully supported by a team that cares.
