Snippet from the article:
Hair loss is often a depressing signature of chemotherapy, particularly disturbing for women who have to undergo treatment. One way to help prevent hair loss during chemo sessions is to cool the scalp, narrowing blood vessels around hair follicles and slowing the uptake of the poison in the area.
A system called DigniCap from Dignitana (Lund, Sweden) has just been FDA cleared for final clinical trials and may soon become available in the U.S. to help prevent chemo related hair loss. DigniCap consists of a touch screen equipped refrigeration and control unit that monitors scalp temperature and delivers cooling liquid to the inner cap.
We have discussed the concept in a series of previous posts about a device called the Cold Cap. It seems that the technology has gotten better since we wrote about it.
