Wearable Scalp Sensors: Monitoring Follicle Health in Real Time
Learn how new biosensors track follicle hydration, stress, and inflammation continuously.
Engineers are developing wearable biosensors that track scalp physiology the same way smartwatches monitor heart rate. A 2025 report in Advanced Healthcare Materials unveiled a flexible, transparent patch capable of detecting hydration, pH, and cortisol levels directly from the scalp surface.
- Sensors used microfluidic channels for real-time biochemical readings.
- Cortisol detection offered insight into stress-induced shedding.
- Bluetooth integration allowed data sync with mobile wellness apps.
- The patch maintained comfort and adhesion even during exercise.
Continuous scalp monitoring bridges personal wellness and clinical dermatology. It opens the door to preventive care and early alerts for stress- or hormone-related hair changes.
The current prototype is expensive and has a limited battery life.
