Hair Growth Guarantee

We are so confident that consistent use of the Kayr Scalp Massaging Brush will renew your hair's thickness and fullness that we back it with a 60-day money-back guarantee.

If you use the Kayr Brush as directed for 60 days and do not see noticeable results in hair regrowth and/or reduction in thinning, simply return it within 60 days of your purchase date for a full refund of the purchase price.

To qualify for the refund, we ask that you provide proof of purchase along with dated photos or videos documenting your use of the product over the 60 day period. This helps us verify that the Kayr Brush was given a fair chance to stimulate renewed growth.

Photos should show your hair's condition before starting use, and after 60 days of use. Videos should demonstrate proper use of the brush as directed. This protects all our valued customers by ensuring the guarantee is fairly administered.

We also welcome your feedback on why the Kayr Brush did not meet expectations. This helps us continue improving and innovating. Please email your documentation, feedback and request for refund to and we will evaluate your eligibility for our Hair Growth Guarantee.

We stand firmly behind our products and confidently offer this guarantee because we have seen the Kayr Brush deliver dramatic results time after time. We cannot wait for you to be our next success story!
