Long Time Customer here!
I've been using my Kiierr MD Laser caps for about 3 years. In 2020 I lost almost all my hair due to Talogen Effluvium. I tried Rogain, pills, and another popular companies laser cap. Nothing. I was stuck in a chronic phase of hair loss. Friends would ask if I was having chemo! Then in 2022 I started using the Kiierr Laser Cap along with the Kiierr supplements and shampoo/conditioner. . . my hair started growing back! Slowly but surely. I still am using my cap and my hair isstill growing. . . slowly but surely! Their customer service is also wonderful!
