Can a cap prevent hair loss from chemotherapy?

Several news reports this week have highlighted the supposed benefits of placing a cold cap on the scalp to prevent hair loss from chemotherapy. While these reports have emphasized the experimental nature of the device — it hasn’t yet been approved by the US Food and Drug Administration — some women have been using them on their own.

A handful of breast cancer patients at Dana-Farber Cancer Institute have rented these caps from a British company for about $450 a month — they’re not covered by insurance — packing them on dry ice to bring to their chemo sessions. The caps need to be replaced every half-hour or so when one loses its chill to keep the scalp cold and, in theory at least, prevent chemotherapy agents from getting to hair follicles and destroying them.
