What Is Cold Capping?

While cold caps and scalp cooling systems differ from manufacturer to manufacturer, all work by narrowing the blood vessels beneath the skin of the scalp to reduce the amount of chemotherapy medicine that reaches the hair follicles-thus reducing hair fall. 

There are two main types of cooling systems: Machine scalp cooling systems which are leased by hospitals and require less maintenance, and manual cold caps that are kept in biomedical freezers and require frequent changing. Both options show tremendous success at reducing chemotherapy related hair loss, although machine scalp cooling systems are the only unit currently approved by the FDA. Check with your healthcare provider to find the best option for you or visit for additional information. 

Check with your health insurance company to find coverage options as well as the manufacturer of the system you plan to use.
