Before you shop at Kiierr

About Kiierr

Kiierr began as a solution for one person’s thinning hair and grew into a brand recognized by dermatologists and trichologists alike. Their flagship products are FDA-cleared low-level laser therapy (LLLT) caps, designed to stimulate follicles at the cellular level and encourage regrowth without the side effects linked to harsh topical or prescription treatments. In addition to laser caps, Kiierr now offers supplements, skin devices, and beauty tools that support a holistic approach to hair and skin health. Customers often highlight the simplicity of use. Slip on a cap while commuting, working, or relaxing at home, and the peace of mind that comes with clinical backing. For anyone just starting to notice thinning or looking for a long-term maintenance plan, Kiierr provides discreet, science-driven solutions built to fit everyday life.

Questions shoppers ask about Kiierr

What’s the shipping and delivery policy?

All U.S. orders ship free with two-day delivery once processed (allow 2 to 3 days for handling). International shipping is available for a flat rate that appears at checkout. If you need guaranteed overnight shipping, it’s available at an extra cost.

What’s the return and growth guarantee?

Kiierr offers a 7-Month Growth Guarantee on laser caps: if you don’t see noticeable results within that window, you can return the cap for a refund. Beauty devices and skincare tools have a 60-day satisfaction guarantee. You’ll need to request a return authorization before sending items back.

Is there a warranty?

Yes, all laser devices come with a 2-year warranty covering defects or malfunctions. An extended plan is available, adding up to three extra years of protection. This ensures your cap is covered for long-term use.

Does Kiierr accept insurance or HSA/FSA?

While insurance won’t cover hair restoration devices, many customers use HSA or FSA funds to purchase laser caps. Kiierr provides itemized receipts that meet most administrators’ requirements.

Are refurbished devices safe?

Yes, refurbished caps are inspected, tested, and certified before resale. They include the same warranty and money-back guarantee as new units, so there’s little downside aside from cosmetic packaging differences.

What’s included with a laser cap purchase?

Most cap packages ship with the cap itself, a portable battery pack, charger, baseball cap-style cover, and carrying case. Higher-tier bundles may add supplements, shampoo, or conditioners for a full regimen.
