Aculief doesn’t just give you fast headache relief… it’s also super comfortable and relaxing! That’s because Aculief doesn’t feel “freezing cold”, even though it’s cool enough to instantly start reducing your headache. We call this the “perfect temperature”.

Your Aculief hat is engineered to stay at the perfect temperature for as long as it takes to relieve your headache. Each Aculief comes with medical-grade gel packs that hold the perfectly cool temperature longer than any other solution (up to 25 minutes) to help you get relief from even the most intense headaches.

Still not sure if you'll like it? Try it out for yourself for 30 days and see why 1 million people all over the world trust Aculief to relieve their headaches!

Aculief is always just a few seconds away from soothing even the toughest headaches.

For instant access to cold therapy, we recommend storing Aculief in the freezer or refrigerator (depending on your comfort level). That way, no matter when you feel a headache coming on, you’ll be able to grab Aculief and instantly start fighting back (in the most relaxing way). Many customers keep multiple Aculief’s in the freezer to extend their therapy times with back-to-back sessions.

After putting Aculief in the fridge or freezer, it will typically take 1-2 hours to reach the perfect temperature.

Aculief’s dual therapy of cold therapy & light compression makes it suitable for ALL types of headaches. From migraines to stress and tension headaches, Aculief is designed to reduce the pain at the source by constricting blood vessels and reducing inflammation. This helps provide fast, natural relief no matter what type of headache or head pain you’re experiencing.

Yes! Aculief can also help with other types of pain. The Aculief Headache Relief Hat can easily be shifted toward the back of your head and away from your eyes if you have pain in your upper neck. Aculief can also fold flat and be placed directly on other areas of the body that hurt.

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.

It sure is! You’ll be able to take Aculief on and off in seconds. Most of our customers describe putting it on as a refreshing and relaxing experience – it’s kind of like your own little spa treatment.

To put on the device, simply slide it over your head (like you would a normal hat) and relax. Over the next few minutes, your headache pain will begin to melt away. When you're done, simply remove the hat and store it back in the freezer or refrigerator until you're ready to use it again.

Yes, Aculief is one-size-fits-all. It’s all thanks to the buttery-soft and breathable fabric that stretches as needed to provide a comfortable fit on any head shape and size. It’s perfect for both adults and kids! Many customers describe it as having a cool pillow around your head. The stretch fabric allows Aculief to hold the frozen gel packs in the perfect place, ensuring they target all the areas that may be causing you pain with light, comforting compression.

Yes! Washing Aculief is easy and only takes a few minutes. For the best results, we recommend cleaning it with a damp towel soaked with hot water and a mild detergent. You can also wipe it down with a non-toxic sanitizing wipe. You should always let it air dry (it only takes a few minutes).

Note: To prolong the life of your Aculief, we do not recommend submerging in water or machine washing it.

Yes, it is completely safe to sleep with Aculief on. If you’re struggling with headaches at night, Aculief could be the answer you’re looking for. Research has shown that applying temperature therapy can help promote sleep, making Aculief ideal for anyone who gets migraines at night or first thing in the morning.

Aculief’s breathable, lightweight, and cushiony gel packs also make it excellent for sleep. Whether you’re a side, back, or stomach sleeper, you won’t be disturbed by Aculief… it’s designed to be comfortable even when worn for a long time. Don’t forget that Aculief includes a special eye cover that blocks out light, making it even better for sleep (or even a quick nap).

Aculief is highly adaptable, meaning you can wear it however you like – as long as you’re getting relief, it’s working. It all comes down to what you're doing and where you’re feeling pain. You can even place it over your eyes when you want to block out the light and enjoy the cooling effects of Aculief in the dark.
