What to Know About Using ‘Cooling Caps’ During Chemotherapy  

Thinking about freezing your head during cancer treatment to save your hair? There are a few things you should know. But first, here’s a quick overview of how it works: Chemotherapy patients wear an ice-cold, helmut-like hat during infusion sessions. The idea is that the cap freezes the scalp, so chemo meds don’t circulate in that area. You generally still lose your hair on other parts of your body, but the hair on top of your head will be saved. You’ll need coolers, dry ice, extra caps and a volunteer who can help you manage the process. Every thirty minutes or so, as your cap thaws, you have to replace it with a fresh, ice cold one. People who have gone through this process say that “cooling caps” is a misnomer. “Freezing caps” is more accurate. For the process to work, the caps have to fit tight, and they’re chilled to negative 30 degrees. While specific instructions may vary from one user to the next, you typically start wearing your cap an hour or so before your chemo infusion starts and keep it on for an hour or so after you finish. So, if your chemo session takes several hours…well, it’s a long time to have a frozen head. You should also know that certain factors can make these caps less successful. For example, if your hair is super thick, you might not be as lucky as someone whose hair is thinner. The thinking is that thick hair prevents caps from freezing the scalp adequately, and in that case, hair loss can still happen.

    My sister is going into chemo soon, and we’ve been considering trying a cooling cap to help save her curls. I appreciate how you explained the way the cap works, keeping the chemo from circulating in the scalp, and it’s good to know that we should avoid brushing, pulling, or stressing the hair in any way during chemo sessions. We’ll be sure to discuss the option with our oncologist to ensure that a cooling cap will work well with her particular chemo needs, but I’m sure it’ll be fine, as the chemo is for ovarian cancer and so the cancer itself is nowhere near the scalp.
