It has a name. Cutaneous allodynia — pain caused by stimuli that shouldn't hurt. A ponytail. A pillow. Your own fringe brushing against your forehead.
Up to 80% of people with chronic migraine experience it during attacks. It's the result of central sensitisation in the trigeminal pathway, and it's the reason most "rescue" products quietly make things worse — rigid ice caps, weighted masks, anything that adds pressure to a scalp that's already in revolt.
Kalmely was designed in conversation with this. Even compression. Adjustable warmth. No spikes. No cold-shock. No straps cutting into a sensitised scalp.
"I had to start sleeping with my hair down because even a ponytail triggered worse pain. I'd given up on anything that touched my head."
