The Headache Relief Hat is a patent-pending hot and cold therapy device that provides natural relief for all types of headaches – tension, sinus, cluster, migraines, and more. It’s unique for three main reasons: - It provides both hot and cold therapy in one easy-to-use device. - It’s the world’s first headache solution to provide 360-degree head coverage, giving you maximum relief. - It’s made from dark materials, which naturally block out sunlight – a common cause of headaches. Combined, this “pain relief trifecta” makes the Headache Relief Hat a must-have for anyone who experiences headaches regularly.
