Neurodermatology of the Scalp: When Nerves and Hair Intersect
Learn how nerve signaling impacts itch, sensitivity, and even follicle activity.

Abstract in Plain English
This study examines how nerve fibers and neurochemicals regulate scalp sensitivity, itch, and hair cycling. It highlights the emerging field of neurodermatology — where neural and skin systems directly interact.
Key Findings
- Sensory neurons release Substance P and CGRP, altering follicle function.
- Chronic scalp stress increases sympathetic activity and inflammation.
- Neuroinflammation may trigger telogen effluvium or diffuse thinning.
- Massage therapy and neuromodulation improved scalp circulation metrics.
Why It Matters
Understanding the neural control of hair opens new therapeutic paths targeting nerves instead of hormones.
Study Limitations
Mechanisms remain partly theoretical; small sample studies dominate the field.
