Formation & geological history
Produced within the hair follicle via biological protein synthesis. Modern era origin (biological growth).
Uses & applications
Biological insulation and sensory function. Industrial uses historically include textiles or wigs, though not typically considered a mineral commodity.
Geological facts
The image provided does not depict a rock or mineral, but rather the crown of a human head showing hair follicles.
Field identification & locations
Not identified in the field as a mineral. Found globally on terrestrial mammals. Identification is based on visual patterns of biological growth.
