Cooler Heads
An FDA-cleared, portable scalp cooling system for cancer patients to minimize chemotherapy-induced hair loss
About Cooler Heads
Cooler Heads was founded in 2018 by Kate Dilligan, a tech entrepreneur and breast cancer survivor. Dilligan's personal journey with breast cancer treatment, where she experienced the challenges of using an antiquated scalp cooling system, directly inspired the formation of the company. Her background in technology combined with her patient experience provided the foundation for developing a more user-friendly and effective solution to a common and distressing side effect of chemotherapy.
The company's core product is Amma™, a portable and FDA-cleared scalp cooling system. This device is designed to help prevent hair loss in cancer patients undergoing chemotherapy. By cooling the scalp to a specific temperature, the system constricts the blood vessels, reducing the amount of chemotherapy drugs that reach the hair follicles. The portability of the Amma™ unit distinguishes it from older, more cumbersome systems, allowing for greater patient comfort and convenience. It is the only portable, FDA-cleared device of its kind available in the market.
Cooler Heads operates within the medical device sector, targeting oncology patients and healthcare providers. The business model appears to involve the sale or leasing of the Amma™ device to hospitals and cancer treatment centers, as well as potentially direct-to-patient services. The company also provides resources and support for patients preparing for scalp cooling treatment, indicating a patient-centric approach.
