Abstract

Hair (Kesha) in Ayurveda is more than a physical feature; it is an indicator of systemic health, a diagnostic tool, and a therapeutic focus. Classical Ayurvedic texts describe Kesha as either a Mala (waste product) or an Upadhatu (secondary tissue derivative) of Asthi Dhatu, with detailed insights into its physiological formation, diagnostic relevance, and therapeutic maintenance. This article explores the Ayurvedic perspective on Kesha in depth, including cultural-historical references from Vedas, Puranas, and Itihasa, alongside contemporary biomedical correlations. It also outlines gaps in current research and suggests future directions for integrative trichology. By synthesizing traditional and modern insights, the paper highlights the potential of Kesha Sharira in preventive and clinical dermatology.

Key words: Kesha, Ayurveda, Asthi Dhatu, Upadhatu, Dhatu Sarata, hair disorders, integrative dermatology, trichology, Parikshya Bhava.
