Does the penguin cold cap therapy work ...to keep hair from falling out due to chemotherapy for breast cancer?

Sometimes: Don't count on it, but i've seen it work. It takes a lot of motivation, and, can be a little uncomfortable. But, if motivated, worth a try!

Sometimes: It is very uncomfortable and cumbersome but works in some patients. The hair loss during chemotherpay is completely reversible and usually 100 days after end of all chemotherapy your hair will grow back.
