100% Money back Guarantee

We stand behind the effectiveness of our products 100%. Try any of our laser caps (148 or 272) or complete hair growth system today risk free. If you do not see results after 7 months (to be eligible you must use your device as directed for a minimum of 7 months), you can return your laser cap for a full refund.

We pride ourselves on being the #1 customer service company in the industry with zero hassle returns and extremely helpful customer service staff to help you along the way. Simply email us at [email protected] for return process instructions.


Return Requirements:

  1. You must submit a before photo when you register your device at www.kiierr.com/warranty within 45 days of delivery.
  2. Your return must be sent back to us within 7 days of receiving your RA number.
  3. We do not accept returns or offer a return/refund option on consumable products such as shampoos, conditioners and vitamins.
  4. Due to the public (FDA clearance) and extensive proven results of our products (95%+ for women and 90%+ for men), we require date stamped before/after photos to be submitted if a request for refund is made on the basis of no results.
  5. We are only able to offer a full refund and return on the basis of non-results of hair regrowth.
  6. You must include all components which came with the cap (i.e. cords, user manual, laser cap, ball cap, etc.) and must be in clean, working condition.


Important notes:

  • We do not accept returns on caps which have not been used for the full 7 months trial. We are committed to providing life changing products with a great return policy, however we cannot afford to offer a full money-back return if a customer does not give our products a fair try for 7-months.
