Details: There is no doubt that the headache cap helps in the management of migraines/headaches. On a couple of occasions I was able to abort the headache by wearing the cap. Yesterday, I had a bad headache, so I took my prescription drugs in mid afternoon, knowing that I would have to follow it up with more stronger prescription drugs in the evening. Instead I wore the cap for an extended period while I watched television. I was able to almost completely annihilate the headache and did not take a second dose of prescription drugs - a definite success.
