Patient Information

  • AGE: 65-year-old Female
  • DX: L invasive ductal carcinoma ER+, PR-, HER2+
  • HAIR TYPE: Fine, thick, slight wave, colored
  • FACILITY: The University of Arizona Cancer Center, Tucson, Arizona
  • WHY SCALP COOLING: I wanted to maintain my privacy both personally and professionally, to control something amid the chaos, to look healthy for myself and my husband, and to not have baldness as a continuing reminder (for months) of my cancer battle.


Patient Experience

“Cap is the best design available for comfort, ease of use, and efficacy. Amma is small, quiet, and easy to use , allowing me to be self-sufficient. The training to use the machine was thorough and clear; team members at Cooler Heads are engaged, responsive, thoughtful, genuine, and caring. My biggest wish is that Amma was accessible to everyone. Having a choice in your care during cancer treatment is powerful.”

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.”

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.

“Cancer patients undergoing chemotherapy are dealing with the hardest challenge one can face; keeping their hair is critical to their mental health, their sense of self, and their recovery process.”
