Hi Susan,
Cold caps work as much as 90% of the time, and are effective with all chemo drugs. Patients using the cap system available in the US do not lose 50% of their hair. All patients have some shedding sooner or later, as the oldest hair follicles can not take even a small amount of trauma. But noticeable hair loss is the exception, not the norm. Our website
www.rapunzelproject.org lists about 50 US oncology locations that not only have patients using cold caps, but have opted to support those patients by accepting a biomedical freezer from us, to make cap use easier and less costly. Hundreds of other locations have patients using caps, but with no freezer. We would be glad to send you more info if you contact us through the website. The process is not one everyone would choose to go through, and sadly it is not normally covered by insurance. We just believe all patients should know about it and make the choice that is best for them. Best wishes to you.
Nancy and Shirley, The Rapunzel Project
