Keratinisation
Definition
Differentiation that produces durable keratin-rich material while altering cellular structures. Hair formation, retention and shedding involve different structures and processes. Document orientation and recovered end condition where these affect examination.
- Context
- Hair biology
For example, formation of a durable hair shaft alters cellular structures, affecting how recovered shaft material differs from adhering root tissue.
A proximal end is not automatically a viable root or proof of forceful removal. Morphology, keratinisation and DNA recovery require separate assessment.
