Hair loss is one of the most feared side effects of chemotherapy, even influencing some patients to refuse treatment. But what if there was a way to prevent it? Cooling helmets are gaining attention as a possible solution. Are they safe and effective? Here’s what the latest research reveals.

The Fear of Hair Loss and Chemotherapy Refusal

Hair loss, or chemotherapy-induced alopecia (CIA), is one of the most distressing side effects for many cancer patients, especially those undergoing breast cancer treatment. In fact, studies show that 8% of women may refuse chemotherapy primarily due to the fear of losing their hair.

What Are Cooling Helmets?

Cooling helmets, also known as scalp cooling systems, have been used since the 1970s to mitigate hair loss during chemotherapy. The mechanism is simple: cooling the scalp reduces blood flow to hair follicles, limiting the amount of chemotherapy that reaches them. This can potentially prevent hair from falling out.

There are two main types:

• Manual cooling caps: Pre-cooled glycerine gel caps that are swapped out every 30 minutes.
• Automated cooling helmets: Machines that circulate glycol-based coolant fluid to maintain a constant cold temperature.

What Does the Science Say?

In response to interest from the Quebec Ministry of Health and Social Services (MSSS), the Institut national d’excellence en santé et en services sociaux (INESSS) conducted a comprehensive review of the last 10 years of research.

Key findings:

• Cooling helmets reduce the risk of CIA and improve hair regrowth.
• Hair retention rates ranged between 26% and 77% in breast cancer patients.
• Systematic reviews show up to a 46% reduction in CIA risk.
• There is no significant difference in effectiveness between manual and automated helmets.
• Reported side effects (e.g., headaches, chills, scalp pain) were mostly mild to moderate.

Patient Benefits

Patients who use cooling helmets:

• Report less reliance on wigs or scarves.
• Experience better hair regrowth after chemotherapy.
• Tend to feel improved emotional and psychological well-being during treatment.

However, side effects, especially with manual systems, can lead up to 41% of users to discontinue use.

Challenges and Considerations

While promising, INESSS warns that implementing cooling helmets widely would create new challenges:

• Staffing and workflow implications: Supervision and helmet management add workload for healthcare staff.
• Longer treatment sessions: Patients may require up to 150 additional minutes in the chair.
• Storage, cleaning, and training: Especially relevant for manual systems.

Currently, only three hospitals in Quebec provide cooling helmets free of charge, thanks to foundation funding. Elsewhere, patients must bring and manage their own equipment, often without clinical support.
