alopecia
Let an agent explain alopecia and its kinds in general terms, relay causes, diagnosis and treatment principles from dermatology sources, address psychological and social aspects with attribution, and route personal questions to clinicians.
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 explain alopecia and its kinds in general terms, relay causes, diagnosis and treatment principles from dermatology sources, address psychological and social aspects with attribution, and route personal questions to clinicians.
Loss of hair from the scalp or body, partial or complete, arising from many causes including hereditary pattern hair loss, the autoimmune condition alopecia areata, scarring forms such as frontal fibrosing alopecia, hair loss after illness, stress or childbirth, infections such as syphilis, cancer and its treatments, and rarer conditions such as loose anagen syndrome; alopecia is diagnosed by examination and sometimes biopsy and treated according to cause.
What it is for: Not applicable; a symptom and group of conditions.
It can be explain kinds and causes; relay diagnosis and treatment principles; address social and psychological aspects; route personal questions to clinicians.
Distinguishing features
Symptom with many causes
Scarring and non-scarring forms
Autoimmune and hereditary kinds
Psychosocial impact
What it looks like
Thinning or absence of hair in patches, patterns or across the scalp or body.
Physical character
normal daily shedding: about 50-100 hairs
alopecia areata lifetime risk: about 2 percent - estimates
How it is recognised
Hair loss of any cause
Pattern, areata, scarring, telogen and other forms
Normal shedding and hair breakage are distinct; abdominal baldness in animals is veterinary
