What We Do
We are a global team on a mission to solve the persistent problem of migraine through advanced therapeutic innovations. Our name, CEFALY (pronounced sef‑a‑LEE), is derived from céphalée, the French word for headache, and cephalic, a medical term that means “related to the head.“ Since 2008, we’ve continued to test and improve our proprietary device, CEFALY DUAL, to offer people with migraine a safe and effective, drug-free treatment. While the causes of migraine are not completely understood, current research shows that the largest and most complex cranial nerve, the trigeminal nerve, is heavily involved in the sensation of migraine headache pain. CEFALY DUAL has been specifically engineered to modify pain sensation in the trigeminal nerve through its ophthalmic branch, which runs under the skin of the forehead.
