A bit pricey but can provide relief

This works as some-what a liquid marker with the liquid solution inside the "pen". Similar to an old school white-out, you have to shake it and you release the liquid by pressing the pen against your scalp (since it works as a headache remedy). The pen doesnt provide long-term relief but it does provide a cooling sensation if only temporarily to ease the pain and discomfort! If you don't like the pen/ pressing option, an oil version also exists at the Saje stores.
