Hair cut before cold cap?

Dear Hann, I presume your question is new here. It seems to be in an old chain of discussion. My story is just above. As Abbydog. I recommend trying for sure. I think at most Chemo suites the nurses put the cap on. At least 1/2 hr before the infusion starts. They sprayed my hair wet. It needs to be wet to work well. And the cap needs to fit well. When I had my Chemo, there was a lady with long hair using the cold cap successfully. I don't think it is necessary to cut your hair, so long as the cold gets through to the scalp. Good luck with your Chemo. I was quite lucky. I had manageable side effects. Nothing serious. No nausea. Go with an open mind, but report any problems. The Drs and nurses have advice and solutions to some things. All the very best.
