About HAIRTOSTAY

HairToStay is a national 501(c)(3) nonprofit based in San Francisco focused on subsidizing scalp cooling (cold cap) treatments that can reduce chemotherapy-induced hair loss. The organization operates a patient-facing subsidy program, raises public awareness about scalp cooling, and partners with suppliers and corporate sponsors to expand access for low-income patients. Since its founding in 2016 HairToStay has grown into a national program that both directly awards subsidies to qualifying patients and cultivates industry and philanthropic partnerships to scale funding. In recent years the charity has continued active fundraising (including an annual gala), corporate partnerships, and public outreach while reporting multi-year operating activity and growing financial reserves to support subsidies across all 50 states.

Notable achievements
