Scalp cooling is a treatment that can help minimize hair loss for people undergoing chemotherapy. Several companies manufacture cold caps, which a person can wear before, during, and after chemotherapy.

Chemotherapy is a form of cancer treatment that causes hair loss. Cold caps reduce blood flow to the scalp to minimize hair loss during chemotherapy.

This article discusses how scalp cooling works, where to rent cold caps, and what factors to consider.

Cold caps are helmet-like hats that are tight-fitting and filled with cold gel or liquid. People wear cold caps before, during, and after chemotherapy treatment. The American Cancer Society (ACS) states that cold caps can prevent or reduce hair loss that occurs with cancer treatment.

There are two methods of scalp cooling that someone undergoing chemotherapy can use:

  • Cold caps: People have to keep cold caps in a cooler with dry ice or in a biomedical freezer before wearing them. The cap warms up and thaws during use and requires replacing every 20–30 minutes during chemotherapy sessions.
  • Scalp cooling systems: These are automated systems that attach to a computer-controlled refrigeration machine. The machine circulates a cool liquid around the cap during treatment, which prevents the need to replace it.

In addition, cold caps could reduce the chances of someone developing cancer-related alopecia. A 2021 study suggests that these conditions can be distressing and affect a person’s identity and relationships. Cold caps could help reduce these problems.

Cold caps offer scalp cooling therapy that doctors may also refer to as scalp hypothermia. These devices narrow the blood vessels under the scalp to limit the amount of chemotherapy that reaches the hair follicles. Less exposure to chemotherapy can reduce the risk of hair loss.

A 2017 study found that women with breast cancer who received chemotherapy and underwent scalp cooling maintained most of their hair. However, those who did not get scalp cooling experienced substantial hair loss.

A 2017 review found that scalp hypothermia can reduce alopecia and appears to be effective for people receiving chemotherapy for breast cancer and solid tumors.

A more recent 2018 article suggests that cold cap treatment works better in individuals undergoing taxane-based chemotherapy than in those receiving anthracycline. These are two different types of chemotherapy drugs.

Some side effects that people may experience when using cold caps include:

  • headaches
  • nausea
  • dizziness
  • neck and shoulder discomfort
  • scalp pain
  • forehead pain

People considering using a cold cap may wish to weigh the benefits and downsides.


  • Some companies that offer cold caps provide international shipping.
  • Health insurance coverage may be available.
  • Some nonprofit organizations offer financial assistance for people undergoing scalp cooling therapy.


  • Cold caps are unsuitable for some people with cancer.
  • People may experience some discomfort from the cold temperature.
  • Side effects can occur.
  • Cold caps can be expensive.
