Yes! Aculief’s medical-grade gel packs are carefully placed around the entire hat, making for the perfect application of cold therapy to all areas of your head. A huge reason why the product is so effective is that Aculief makes direct contact and applies cold therapy and light compression to all of your headache relief points. For those who are sensitive to cold temperatures, the Aculief can also be effective at room temperature as the hat still provides comfortable compression and still blocks out light to help anyone with light sensitivity.
