The bandana is made of cotton yarn and can be washed in the washer at 60 degrees celcius. It can shrink after washing but it will stretch again after wearing it and adjust to your head.
You can also give it a wash when receiving it it’s too big and let it dry flat and then it will adjust to your head afterwards. If it’s too small, you can give it a wash, and stretch it while still wet, and then let it dry flat and then it will adjust to your head afterwards.
