Cooler Heads Prevail: A Crash Course in Cold Capping

This post is brought to you by Arctic Scalp Inc. Because nothing says luxury like cryogenic headgear and existential dread.

What the Hell Is Cold Capping?

Glad you asked, even if you didn’t (yet). Cold capping is a technique used during chemotherapy to help reduce hair loss. In plain English: you freeze the hell out of your scalp so the chemo drugs can’t fully penetrate the hair follicles. The theory is that the cold constricts the blood vessels, limits the number of hazardous materials reaching the scalp, so that your hair roots go into hibernation/protection mode.

Sounds fun already, right?

There are a few different ways to do it. Some hospitals offer machine-based cold capping (fancy, automatic, expensive). We didn’t have that option and had to go the manual route with Penguin Cold Caps, which means you wear a literal ice helmet that must be changed out every 20–25 minutes for hours during and after chemo. It’s DIY cryotherapy with a side of advanced logistics and a splash of “WTF are we doing?”

Why Michelle Chose to Do It

Let’s be clear, this wasn’t about vanity.

Michelle didn’t choose cold capping because she’s obsessed with her hair or trying to hang onto some beauty standard. She chose it because she didn’t want cancer to announce itself to the world before she was ready.

Hair loss is the most visible sign of chemo treatment. She didn’t want to walk into a room and have her appearance to do all the talking. Or to look in the mirror and see a “sick” person. Michelle just wanted to maintain a sense of normalcy. Because cancer may be part of her story now, but it doesn’t get to be the whole damn headline.

How It Works

Cold capping isn’t just “pop on a frozen hat and hope for the best.” Especially with the manual system… it’s a whole thang’.

Here’s the basic rundown:

The caps are kept in a cooler to keep them as cold as hell (technically -28°C or lower, but who’s counting). On chemo day, we pick up the cooler with dry ice, three caps, numerous straps and more, and bring them to the Bing Infusion Center like we’re showing up for a picnic in the Arctic.

Each cap gets rotated every 20 to 25 minutes. That means taking the current one off, replacing it with the next fully frozen one, strapping it down tight enough to give a back-alley facelift (Michelle was told it should feel as though I am attempting to rip her head off and she agrees I that I’ve got that part down), and then re-freezing the warm one for later rounds. And this goes on for hours… before, during, and after chemo.

Because of Michelle’s extra special drug cocktail, she gets to cap for 7 hours total. We’re basically there turning her dome into a popsicle from early morning until mid-to-late afternoon.

It’s a full-day freeze-fest.

So… Is It Working?

Short answer: yes, mostly.

Michelle is now halfway through chemo, and she estimates she’s lost about 40% of her hair. Which, for anyone going through TCHP is a huge win. Many people lose all or most of their hair on this regimen, sometimes even while capping.

Her hair is thinner. She “sheds” more than usual. There are a few patches around her hairline that have gotten sparse. But to the average person walking by on the street—or even across the room—you wouldn’t know she’s going through chemo.

And that’s exactly the point. Not to pretend it’s not happening. But to have some continuity. Some normalcy. Some sense of “Michelle-ness” still showing up in the mirror, even when everything else is being hijacked by treatment.

Of course, every cold cap success story comes with caveats. Results vary wildly. Some people lose very little hair. Others lose more than expected and still find it worth it. Michelle’s results so far are firmly in the “worth it” column. If nothing else, she’s kept enough to still feel like herself—and she’ll take that, with a smile, of course.

Side Note: It is common for hair that is shed during chemo to grow back thicker and curlier. I am modestly excited that this may produce a Gilda Radner look for Michelle by next summer (Michelle had to look up Gilda Radner to realize just how clever I can be. It’s funny the pop culture references that we don’t share, even though we have only a modest age gap).

Tangent Alert: How Am I Doing, You Ask?

Since many of you kind, generous humans have asked, “How are you doing, Stephen?”… I’ll take that as permission to make this moment all about me for a hot (or cold) second.

Cold capping sucks for the person wearing the caps. It’s painful, relentless, and piled on top of all the other cancer-related nonsense. But let me tell you, it’s no picnic for the person managing the caps, either.

(if you have in your possession a teeny, tiny violin, now would be the appropriate time to start playing it)

Capping should be an Olympic event. Honestly. It’s up there with being the pusher in a four-person bobsled team. Except instead of national pride or a medal, what’s on the line is my wife’s f*cking hair. And if I mess up even a little (if the cap is a few centimeters off, if it’s not a tight enough fit, if I take too long between swaps) that might be exactly where she sheds.

It’s precision under pressure, over the course of hours, while sitting in a fluorescent-lit, windowless, brown-on-brown-on-beige colored chemo room trying to act like everything’s fine. It’s problem-solving with dry ice and stopwatch timing while your partner is doing the actual hard part: getting poisoned to save her life.

So, when Michelle says, “I think I’ve only lost about 40% of my hair,” my heart sinks a little.

Because part of me can’t help but wonder:

What if I’d done a better job?

Could it have been 20%? Or less?

I know, logically, that this isn’t all on me. There are limits to what cold capping can do, and I was “trained” for a total of twenty minutes the damn morning-of the first treatment. But emotionally? It’s hard. I want to protect her. I want to nail this one damn thing. And sometimes it just feels like too much is riding on this…

That said, Michelle has never, and never would, blame me. She’s gracious and grateful, no surprise there.

Wrapping It Up (Before the Next Cap Swap)

Cold capping is one of the strangest, most high-maintenance things we’ve ever done. It’s uncomfortable. It’s stressful. It’s not cheap. And it turns chemo day into a full-blown endurance event for both of us. No time for movie-watching or coloring books!

But so far? It’s worth it.

Worth it for the sense of agency.

Worth it for the tiny spark of normal in a time when everything feels upside down.

Worth it for Michelle to still feel like herself when she catches a glimpse in the mirror.

Worth it just to have something we could do in a situation where so much feels out of our hands.

We’ve still got a few rounds to go. Still burning my hands on the dry ice, still swapping the caps, still shivering cold for hours on end, still hoping the follicles keep hanging on.

So next time you see Michelle, and you think “Wow, she looks amazing, are we sure she’s even in treatment?”

Yeah. That’s on purpose.

And also? That’s love. In frozen form.

Thanks for riding this out with us. For being here. For reading, messaging, showing up, dropping meals.

That’s what helps thaw the hard stuff.
