Everything the routine needs
Your minoxidil doesn't stay on your head. It dries into your hair, rubs off on your pillow, and ends up on whoever shares it. The Night Kit keeps tonight's dose where you put it, and shows you whether it's working.

Minoxidil usersWhat people who use minoxidil write about it
If you have a dog or cat, this can kill them. Minoxidil is extremely toxic to pets, even just a small drop can make them sick.
You have to wait some time for it to dry a bit on your scalp, if not, all is going to stay in your pillow.
My cat started exhibiting weird behavior shortly after use and I came to learn that Minoxidil is toxic to pets.
Leaves my scalp greasy and makes my head itch so I end up with the goop all over my hands and everything else I touch, too.
This can run down your scalp, get onto clothing and is changing the color of our pillow cases.
Sooo greasy. Had to wear a hat the whole time until I washed my hair.
One month of use and dramatic results. It's so greasy though I only use it at night.
As it leaves a greasy coating on my hair, I can use it at night and wash out in the morning.
Do not use if you have cats. It is extremely toxic to them.
As soon as my hubby forgets to use it, he finds lots of hairs on the pillow.

One rule: the cap goes on dry hair only. At least 2 hours after liquid. After foam, once it is completely dry.
We don't sell minoxidil, and we never will. The Night Cap is an accessory for people who already use it. Your treatment, dose and advice come from your doctor or pharmacist, not from us.
Kit usersWhat kit users say
I was thinking about quitting minoxidil because my cat sleeps on my pillow. Thanks to the waterproof barrier of this cap, not a single drop leaks onto the pillow. I put it in its protective pouch in the morning, and I feel completely at ease.
With the comb applicator, the liquid reaches the scalp without running down my forehead, and thanks to the gloves, I can pet my cat without the paranoia of having to wash my hands. I was just looking for a cap, but I found a great kit that solved all my application problems.
Regular silk bonnets were leaking, but the special design of this cap completely solved the yellow stain problem on my pillows. Zero leakage when you put it on after your hair dries. It doesn't squeeze your head at all during the night.
My wife was really complaining about the yellow minoxidil stains on our pillowcases, and regular silk bonnets leaked the lotion. The design of this cap is truly different. It doesn't feel tight on your head all night and doesn't leak. The only rule is that your hair must be completely dry; if you pay attention to that, there are zero issues. I knocked off 1 star just because there could be a few more color options.
Honestly, the idea of sleeping with a night cap seemed a bit weird at first, but I have 2 cats and didn't want to take any risks. I chose the Black Microfiber one; it's very comfortable, has a loose fit, and doesn't make you sweat. It's still on my head when I wake up in the morning. Also, buying the pieces separately would cost around $120, so getting the kit is a much smarter investment.
For years, I was tired of the cycle: 'apply the drug, wait for it to dry, twist into weird sleeping positions so it doesn't rub off on the pillow.' This kit streamlined the whole process. I apply it cleanly with the bottle, track my shedding with the lens, and once it's dry, I put the cap on and go to sleep. Especially if you share a bed with a partner or have a child, this is an absolute must-have product to prevent the medication from rubbing off on them.

The sleep cap made for minoxidil
It dries into your hair, rubs off on your pillow, and ends up on whoever shares it. Your partner. Your kid. Your cat. The Night Cap keeps tonight's dose where you put it.
She isn't sleeping on a pillow. She's sleeping on last night's dose.

What people try
Or keep the treatment and block the route.
In their words
“…it goes on very greasy and it will stain hats and pillows.”
“This can run down your scalp, get onto clothing and is changing the color of our pillow cases.”
“My cat started exhibiting weird behavior shortly after use and I came to learn that Minoxidil is toxic to pets.”
“…you can't put the liquid on right before bed, unless you want marks on your pillow case.”
Where we stand
Quit your treatment.Fix your routine.
Scroll any hair loss ad and the pitch is the same: minoxidil is dangerous, buy our serum instead. We think that's backwards. Minoxidil has decades of clinical evidence behind it. Most of what's sold as an alternative has a landing page.
Others switch to pills just because of their cat. Oral minoxidil works well for many people, but its most common side effect is unwanted hair on the face and body, in about 1 in 7 patients in the largest study. If the topical is working for you, your pet doesn't have to be the reason you give it up. That's a call for you and your doctor, not for us.
You don't have a drug problem. You have a transfer problem. That's a fabric problem, and fabric is easy.
What's inside
Every piece is sold on its own. Together, with the Triple Layer cap, they cost $111.93 USD. The kit is $69.00 USD.
Keep the drug on your scalp, and off your pillow, your hands and your nightstand.

The night routine
The cap is step four. Steps one to three cost nothing, and you should do them even if you never buy anything from us.
Tie it to a habit instead of a clock. Moving your application earlier is the single biggest fix on this page.
At least 2 hours for liquid, 4 is better. For foam, wait until it is completely dry. Dryness check: touch the back of your hand to your scalp. If it feels cool or tacky, it isn't dry yet.
Residue on your hands ends up on everything you touch next. That includes your pet.
The Night Cap is made for minoxidil: it sits loosely over dry hair and puts a barrier layer between your hair and your pillow. Take it off in the morning. Wash it once a week.
Read this before you buy
Other brands in this space will tell you their product is completely safe. We'd rather tell you where ours stops.
Safety
In 2025 a medical journal described a 28-year-old woman who used 5% minoxidil twice a day, wore a wig all day, and a tight cap all night. Her scalp was covered almost around the clock. More of the drug reached her bloodstream than it should have. She grew unwanted hair on her face, arms and legs, and woke up with swelling around her eyes. It cleared after she stopped.4
That is the opposite of how the Night Cap is used: loose, over fully dry hair, at night only. If you already wear a wig or a tight hat during the day, talk to your doctor before adding a night cap.
Questions
Not if you wait until it's dry. Most absorption happens in the first few hours after you apply it, and the cap goes on after that. If anything the routine helps: product that rubs off on a pillow isn't doing anything for your hair.
The documented problems come from tight, near-constant covering over wet product. The Night Cap is the opposite: a loose dome, over dry hair, for the night only. If you have a scalp condition or wear a wig or tight hat during the day, ask your doctor first.
No, and be suspicious of anyone who says their product does. The cap reduces one contact route, the pillow. Pets are also exposed through your hands, your skin, spills and the bottle itself. Wash your hands, store the bottle out of reach, and if you think your pet has had contact, call your vet or ASPCA Poison Control (888-426-4435) right away. Don't wait for symptoms.
Let the foam dry completely before bed. The foam leaflet doesn't give a number of hours, so check with the back of your hand. Dried residue still sheds from your hair onto your pillow through the night, and that is what the cap is for.
It's cut deep, with an elastic band that sits at the hairline, and it's designed to stay on when you turn over.
No. It's made for minoxidil nights: a waterproof core, a soft lining and satin on the outside. A thin plastic shower cap crinkles, sweats and is off your head by 2am. This one is made to be slept in, and the routine that comes with it matters as much as the cap.
Most minoxidil users are. The cap is unisex and cut extra large, so it fits long and thick hair too. It comes in plain black or navy floral.
A Night Cap of your choice, a satin storage pouch, 30 black nitrile gloves, 30 shed stickers, a clip-on macro scalp lens with an LED ring, a comb applicator bottle and a 90-day tracking card. Every piece is also sold on its own.
At least once a week, with your normal detergent, then let it air dry. Wash it separately from pet bedding.
Free shipping on all orders. Orders ship within 2 business days. Delivery usually takes 4 to 15 days. Unused items in their original packaging can be returned within 30 days of delivery. A cap is worn on your head, so for hygiene reasons we can't take back caps or opened gloves and stickers once they've been used. Full details are in our Refund Policy.
Not for that reason alone. Oral minoxidil is a good option for many people, but it isn't right for everyone. Its most common side effect is unwanted hair on the face and body, reported in 15.1% of cases in a study of 1,404 patients. If you already deal with unwanted hair, for example with PCOS, that matters. If the topical works for you, the pet risk is something you can manage with your routine: apply early, let it dry, wash your hands, cap on. Which form you use is a decision for you and your doctor.
Silk and satin are great for your hair, but they aren't waterproof. Residue soaks into the fabric, and the bonnet ends up on your pillow, your nightstand or under your cat. The Night Cap keeps satin on the outside, so you keep the glide, and adds a waterproof layer in the middle. Whatever you wear, put it on dry hair only.
Keep the treatment. Keep it off your pillow, your face and your cat.
