FAQ - Polar Cold Caps

  • ​​Our caps must be changed every 30 minutes not every 15 minutes like some of the competitors which means less work for you during treatment.
  • We supply you with 6 caps, not 4 like the other companies out there. Our studies show that 4 caps is simply not enough for a long day of treatment.
  • At Polar Cold Caps we supply you with everything needed for the day of treatment at the lowest price available.
  • We utilize a unique gel formula created to out perform the competition by maintaining cold temperatures for longer periods of time.
Our caps stay colder for longer, provide additional support where needed, and are constructed from a superior grade insulating material. Through years of research and extensive testing, we have learned that optimal fitting and the ability to maintain cold temperatures are important key factors to preserving the hair follicles during chemotherapy. Our revolutionary ultra cold gel caps were specially engineered to provide maximum effectiveness by utilizing a superior gel filled strapping system which contours to the entire scalp. This provides an additional layer of insulation which ensures the scalp stays cold while remaining securely fastened throughout treatment. Our caps also utilize a unique gel formula specifically created by industry experts to maintain cold temperatures for longer periods of time to maximize effectiveness while staying flexible for added comfort. These combined benefits allow our clients to achieve optimal results.
The cold temperature of the cap constricts the blood vessels beneath the skin of the scalp, preventing the chemotherapy medicine from reaching the hair follicles, therefore allowing the patient to preserve their hair. This process is referred to as vasoconstriction. The cold also slows down the hair follicle metabolism, making the hair cells dormant or less active, further preventing the absorption of chemotherapeutic drugs. See Scalp Cooling reference diagram.

Overall, cold cap therapy is very well tolerated. For the first few minutes, the patient may experience mild discomfort. The discomfort then dissipates and the patient is fairly comfortable. The most common reported side effects are headaches and coldness. The electric heating blanket provided will be extremely beneficial during this time.
Cold cap therapy has successful proven results for patients of all hair lengths. Be sure hair is completely laid down and not pulled back or placed up while using cold caps.
It is recommended that caps be worn for 1 hr prior to the start of the chemotherapy treatment (premedication infusion is not considered chemotherapy and caps can be worn during this time), throughout the entire chemotherapy infusion process, and the 3 hours following the completion of chemotherapy treatment. Caps must be changed out every 30 minutes during this entire process.

According to Dr. Hope Rugo, director of breast oncology at U.C.S.F, recent clinical trials by researchers at the University of California, San Francisco, and several other medical centers across the country showed that most women who used scalp-cooling caps kept most of their hair. In the largest study, conducted by researchers van den Hurk CJG, Peerbooms M, Breed WPM from 2006 to 2009, included 1,411 patients within 28 hospitals across Netherlands. Results of the Dutch Scalp Cooling Registry showed clear evidence that scalp cooling can prevent chemotherapy induced alopecia.
