Lily is a wearable medical device developed by Luminate to help reduce chemotherapy-related hair loss through controlled scalp compression. Designed with BLOND, it was refined to feel discreet, approachable, and suitable for both clinics and at-home use. The helmet-like form avoids clinical cues, instead drawing from lifestyle design to create comfort and dignity for patients. Features include lightweight construction, cushioned straps, removable chin support, intuitive touch controls, and a recycled PET carry case, balancing medical credibility with user-centered design.
