Our story

Cooler Heads was founded in 2018 by Kate Dilligan, a tech entrepreneur and breast cancer survivor, to protect the dignity, privacy, and identity of cancer patients. After Kate was diagnosed with breast cancer, she spent $8,000 on traditional cold cap therapy. After talking with countless cancer patients frustrated by the high cost, poor fit, and difficulty of use of existing methods, Kate was determined to engineer a better way.

Cooler Heads’ Amma is the only portable, FDA-cleared scalp cooling unit available. With Amma, facilities across the country can now provide this treatment to eligible patients without compromising space and chair time.

Patient Information

  • AGE: 48-year-old Female
  • DX: L Breast ca (er+, pr+, HER2+)
  • HAIR TYPE: Straight, above shoulders, thin
  • FACILITY: Sharp Grossmont Hospital Outpatient Infusion Center, San Diego, CA
  • WHY SCALP COOLING: I was determined to continue working full time during my chemotherapy treatment. My job requires me to travel quite a bit, and I wanted to maintain discretion and normalcy while continuing to work in a very public environment. I also wanted to look in the mirror and still see myself as “healthy”, while easing the minds of my closest loved ones.


Patient Experience

“I was thrilled to have the opportunity to use the Amma system. I felt that the results and ease of use would be better than the other choices currently available. As one of the first patients at the infusion center to use Amma, there seemed to be a lot of excitement and interest from both nurses and other patients when I would use the system. The unit is compact, and takes minimal space. It also allows for quick, simple trips to the restroom or short walks if you just want to stretch your legs a bit.

The best experience I had throughout my treatment was watching the reaction various medical providers had when they would see me. When I went for my half-way and end-point chemotherapy mammograms, ultrasounds and MRIs, every clinician I saw was confused when I walked in. Each one asked “We are seeing you for your post chemo scans, correct?”, with a puzzled look on their faces, because I had kept most of my hair. I hope every other patient gets to experience that same feeling of satisfaction and comfort.”

Cooler Heads Story
as told by Founder Kate Dilligan


More about Chemo and Preserving
Your Identity with Cooler Heads

Chemotherapy, while a crucial weapon in the fight against cancer, often comes with the challenging side effect of hair loss. At Cooler Heads, we understand the emotional toll this can take, and we’re here to offer a solution that helps you keep your hair — introducing our cutting-edge scalp cooling system called Amma™. Scalp cooling is the mechanical version of cold caps – think of it as a less laborious process that provides patients with the confidence to use our system independently without relying on someone else to manage the caps for them.

Understanding Chemotherapy
Treatment Side Effects

Chemotherapy is a potent treatment that targets rapidly dividing cells, including cancer cells. Unfortunately, it also affects healthy cells, such as those in the hair follicles, leading to hair loss. This side effect can be emotionally distressing for many patients, impacting their self-esteem and overall well-being.

The Science Behind Cold Capping

Our scalp cooling system Amma™ works to combat the impact of the powerful impact of chemotherapy drugs on the patient’s hair follicles.. By cooling the scalp to a low temperature, the blood vessels constrict, reducing the blood flow to the hair follicles. This, in turn, limits the amount of chemotherapy drugs that reach the follicles, reducing hair loss.

Preserving your Hair
for Faster Growth After Chemo

Preserving your hair during chemotherapy not only helps maintain a sense of normalcy but also aids in the post-treatment phase. After completing chemo, most individuals experience faster hair regrowth since their hair follicles were not as damaged by the chemotherapy had they not used scalp cooling.  Amma™ empowers patients with both confidence during chemotherapy  and a quicker recovery to normal.

Scalp Cooling vs Cold Capping

Facing chemotherapy is daunting, and one of the most emotionally distressing side effects is hair loss. However, amidst this adversity, there’s a solution — scalp cooling.  In comparison to traditional cold capping methods, scalp cooling is the superior alternative. Its precision, user-friendly design, efficiency in preserving hair follicles, adaptability, and reduced reliance on external assistance makes it a groundbreaking solution for individuals seeking a more comfortable and effective approach to maintaining their identity during chemotherapy. Scalp cooling is not just a solution, but a beacon of hope for a future where the impact of chemotherapy on one’s appearance is minimized, and dignity is preserved.


Precision Cooling with Amma™

Unlike cold caps, which rely on manual application and replacement, our Amma™ scalp cooling system is designed for precision and consistency. Amma’s advanced system maintains a controlled temperature throughout the chemotherapy session, ensuring optimal protection for hair follicles.


A User-Friendly Experience

Amma ™ is a user-friendly and hassle-free experience for patients. With automated temperature control, individuals can focus on their treatment without the need for constant cap replacement every 20 to 30 minutes. This not only reduces the burden on patients but also allows for a more seamless integration of the scalp cooling process into their chemotherapy sessions.


Efficiency in Preserving Hair Follicles

The precision and constant temperature maintenance of Amma’s scalp cooling system contributes significantly to the effectiveness in preserving hair follicles. By minimizing blood flow to the scalp consistently, Amma™ creates a protective barrier against the impact of chemotherapy drugs, reducing the likelihood of hair loss.


Reduced Reliance on External Assistance

Unlike cold caps, which often require the assistance of a friend, family member, or hired “capper” to replace them during each session, Amma’s™ system operates autonomously. This reduces the need for constant external assistance, empowering patients to manage their scalp cooling experience more independently and with greater confidence.



Investing in Future Comfort

Scalp cooling represents an important step toward the future of cancer care. By choosing scalp cooling over traditional cold capping, individuals not only enhance their immediate treatment experience but also invest in the preservation of their emotional well-being and overall quality of life during and after treatment. 


Preparing for Scalp
Cooling with Amma

Preparing for Scalp Cooling with Amma™ involves a combination of communication, education, and personal readiness. By taking these steps, you set the stage for a positive and empowering experience during your chemotherapy journey. Cooler Heads is committed to supporting you every step of the way, providing not just a cooling system but a companion in your quest to retain your identity and face cancer treatment with dignity. Here’s a guide on what you need to do to prepare yourself for Scalp Cooling with Amma™ before your treatment day.


Consultation with
Your Healthcare Team

Before diving into scalp cooling, it’s crucial to have an open conversation with your healthcare team. Discuss your interest in using Amma™ and ensure that it aligns with your overall treatment plan. Your medical professionals can provide insights into the compatibility of scalp cooling with your specific chemotherapy regimen and offer personalized guidance.


Educate Yourself

Understanding how Amma™ works and what to expect during the process is empowering. Take the time to educate yourself on the technology behind scalp cooling and its potential benefits. Cooler Heads will provide you with resources, information, and answer any questions you might have that can help you feel more informed and prepared for the experience.


Fitting Your Cap

A proper fitting ensures that the cooling cap is comfortable and securely placed on your head during the treatment. So, we’ll show you how to fit it! On the day of treatment, typically the patient will prep for scalp cooling with their accessories which consists of a prepping hair, applying the cooling wrap that has been pre-fit-making small adjustments, then finishing with compression cap for a snug fit, then they will take their pre-meds to cool before chemotherapy begins.


Prepare for Treatment Day

On the day of your treatment, it’s essential to arrive prepared. Dress comfortably and consider wearing a button-down shirt to make it easier to put on and take off the scalp cooling cap. Bring any personal items you might want during the session, such as a cozy blanket, lip balm, a book, headphones, a journal to document your experience, a Netflix Series or crossword puzzle.


Arrange Support

While Amma™ is designed for ease of use, having a friend or family member accompany you during your treatment session can provide emotional support. Our Support Team is available for phone call or text anytime you need them. That includes during your treatment for an extra pair of eyes and ears!


Hair Care Instructions

How you treat your hair outside of chemotherapy can be just as important as scalp cooling. We will provide you with some hair care tips and tricks to help manage your hair at home.


Embrace the Experience

Scalp cooling with Amma is not just about preserving your hair; it’s also about empowering yourself during the chemotherapy journey. Embrace the experience as a positive step toward maintaining a sense of normalcy and confidence. The cooling process is designed to be as comfortable as possible, allowing you to focus on your well-being.
