Menstrual migraine

Cold works on a migraine on two conditions: it has to start early, and it has to keep going. Every cap on the market sells you half of that. The gel warms up. Refreezing takes two hours. A period attack runs all day. So we put two caps in the box, with two sealed freezer bags. One is always frozen. Freeze both the night before your window, swap in five seconds, with no gap in the cold. Women were already buying the second cap themselves. We stopped making them.

The week that repeats

the one migraine you can see coming, and nobody takes it seriously.

The days it will land are already on the calendar. In a diary study of 500 women with migraine, more than half had attacks returning in the same five days of the cycle.

The mechanism

freeze both. swap when it warms.

Two identical gel caps, on rotation.

One goes on, over your forehead and eyes. The other waits flat in the freezer, in its sealed bag.

When the first cap warms, you swap. Five seconds, eyes closed, no straps, nothing to assemble. Keep rotating, and the one going on your head is always the one from the freezer.

Day 26 you freeze both. Day 28 you are not improvising.

How ChillCrown works The payoff

what the second cap changes about the period week.

Always a frozen cap readyOne cap is a countdown. With two, a frozen one is waiting when it ends, then keep rotating. The swap takes five seconds and you never leave the room.
You are prepared, not ambushedOne recurring reminder, two days before your window opens: freeze both. That is the whole ritual.
Darkness comes with the coldIt covers your eyes, not just your forehead. In the period window light sensitivity runs higher than at any other time, so the blackout is half of the point.
A layer your medication does not have to sharePainkillers and triptans cap out around two days a week before they cause headaches of their own. Cold has no ceiling and no interaction.
Odorless gel, sealed storageSmell is the number one complaint about gel caps. Ours is odorless, and two sealed freezer bags come in the box.

First cycle versus the third: same five days, but both caps went in the freezer on the reminder day, the swap is a reflex now, and the night ends asleep instead of counting minutes in the kitchen.

No hype

what we are not going to tell you.

We will not tell you this stops or shortens a menstrual migraine. It does not, and nothing you can buy in a box does. Estrogen withdrawal has no opinion about a cap.

ChillCrown is comfort during the attack: cold, darkness and gentle pressure, with a frozen cap always ready instead of one that quits mid-attack.

The strongest evidence for cold itself is a small open-label study: a cold gel cap during attacks, average pain from 7.9 down to 5.5 out of 10. Two caps are there so the cold does not stop when the first one warms. Encouraging, not a promise.

If your attacks are frequent, worsening or new, log two cycles and take them to a doctor. This runs alongside real treatment, not instead of it.

Our story

why we built ChillCrown.

The story behind ChillCrown

ChillCrown started in the reviews section.

Under the five stars of every best-selling migraine cap, the same complaint kept surfacing: it goes warm too soon. People loved the cold and resented the countdown.

Then the pattern underneath it. Women buying a second cap out of their own pocket so one was always frozen. Some ran three or four, like a pit crew.

The fix already existed and nobody would sell it on purpose. So that became the product. From someone who counts freezer minutes too.

FAQ

questions, answered straight.

Does it stop a menstrual migraine?
No, and we will never claim it. The trigger is estrogen withdrawal and no cap touches that. This is drug-free comfort during the attack. If your attacks are frequent, worsening or new, log two cycles and take them to a doctor.
I do not get hormonal migraines. Is this still for me?
Yes. The problem it solves is duration, whatever your trigger. We lead with the period window because it is the one attack you can see coming. Almost everyone who buys it for the window uses it the rest of the month too.
What happens when a cap warms up?
You swap. Every gel cap warms up on a warm head, the same physics for all of them, which is why ChillCrown comes as two. The second cap is waiting in the freezer, fully frozen after roughly two hours. After that the rotation keeps going with caps that have had their turn in the freezer: cold, just not freezer-fresh. If your attacks run long, add a second pair: four caps mean more fully frozen swaps.
It is too cold when it first comes out. Am I doing it wrong?
No, and you are not the only one. Put it on straight away, a cap that waits on the counter loses its cold. If the first minute bites, lift it off for a minute, then put it back. What does not work is shortening the freeze: under two hours and it runs out of cold sooner, which is the problem you bought it to solve.
What if I am at work or not near a freezer?
Then it is the wrong tool for that hour, and we would rather say so. The rotation needs a freezer within reach. Any office or hotel freezer works, and a cooler bag carries a frozen cap for a few hours.
Which pack should I get?
The 2-Pack is the system: one on your head, one in the freezer. Start there. The 2-Pack + Guide adds the 47-page guide for $9 more. The Full Window Set adds a heated shiatsu neck massager and a heated neck wrap for comfort around the caps. If your attacks usually run past an hour, or you want a frozen pair at work, add a second pair: it comes with the guide free. You have thirty nights to decide.
Does the gel smell?
The gel is odorless, and two sealed freezer bags come in the box so the caps never absorb freezer odors. Built for attacks that come with nausea and scent sensitivity.
Will it fit me? Can I sleep in it?
One size, head circumferences of roughly 50 to 61 cm. The gel stays soft when frozen and there are no straps or hard parts, so side sleeping is fine.
What is the catch?
Each cap still warms up, like every gel cap. Physics is physics. It works because there are two, and it asks one habit: put the warm cap back, and freeze both before your window opens.

The purple color was more vivid than I expected, but the feeling of using the product is like, "Wow?!" It seems like I can even sleep with it on. I haven't had a migraine day yet so the effect is still unknown, but I like the slightly dark feeling. The front part has a gel-like, squishy texture like a cushion, and the back is made of fluffy jersey material.

It has arrived safely, it's a great product, it's not the first time I've bought it. I have problems with migraines, and although it doesn't cure them, it does relieve me quite a bit. I highly recommend it; you have to wash it by hand. 👍🏻👍🏻👍🏻😊😊😊

Very good, excuse my face, but I am sick with a severe headache and this helps me a lot. I highly recommend it.

I ordered two masks at once. I already have a similar one and took it as a gift for a migraine sufferer. During severe migraine attacks, such a cold mask is a lifesaver 👍❤️‍🔥

K
Kellee Halvorson

For migraines, that's exactly it! The mask with gel filling is soft to the touch, a bit soft, but holds its shape perfectly. The fabric stretches a little, fits any head. It feels great in the freezer. I have a similar mask there and it stays 🥰❤️‍🔥👍

Perfect, fits very well on the head. The material has a very pleasant feel. It's very comfortable. It greatly relieves the headache.

Very good product, I didn't even have to put it in the fridge and the gel part felt cold right away, it fits very well, you feel instant relief and even more so when you take it off to reduce the migraine.

Just as the description says, large size covers the entire face, highly recommended, doesn't squeeze too much.

It’s a good product and efficient. However the gel is only on the front part of the mask. Would have been better if it was on the back as well. Overall it’s a great product for the price!! !

This is very good quality. It is snug when you put it on, but it’s not uncomfortable. The cooling gel is very nice.
