The service provided by Shane and Arctic Heat has been outstanding right from the beginning. I bought a 3 pack of cold caps to use whilst undergoing chemotherapy for breast cancer. I would highly recommend getting the 4 or 5 pack as you apply the cap before, during and after treatment. 15 months after treatment, I have a full head of hair and unbelievably, I have more hair now than before I started chemo. I’m so happy to endorse this product and have passed my caps onto a friend who is also undergoing chemo. Thanks Shane.
