Let an agent handle hair by type, biology, care, conditions and uses, routing medical concerns to professionals.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle hair by type, biology, care, conditions and uses, routing medical concerns to professionals.
A thread-like strand of keratin growing from follicles in the skin of mammals, including human hair and animal fibres such as goat, camel and pig hair; hair also forms fur and is used in textiles and brushes.
What it is for: Insulation, protection, sensation, appearance and, for animal hair, fibres and materials.
It can be care for hair and scalp; understand hair growth; seek help for sudden hair loss; use animal fibres responsibly.
