Chemotherapy without hair loss? Cooling cap in works

(CBS News) Hair loss is one of the most visible effects of chemotherapy. But chemotherapy without losing one's hair may soon be possible. Scientists have developed a hood that cools the scalp during chemotherapy, reducing the circulation of blood - and, accordingly, the poisons from chemotherapy. As a result, hair roots survive.

The study is currently being carried out at the Jerusalem hospital in Hamburg, Germany.

Dr. Kay Friedrich of the hospital says, "It is an illusion that the whole hair can be preserved. About 10 to 30 percent of the hair gets lost. But the better the starting conditions are, full and strong hair, the less you see the loss of the hair."

What do patients think?

One says, "It's unpleasant, it does not feel good. But it serves a good purpose."
