What is it?
Hair loss may be hereditary or temporary, including after illness, stress, weight loss or iron deficiency.
Symptoms and important signs
Gradual thinning or increased shedding; pattern and duration are important.
How is it assessed?
Establish the cause with a clinician before purchasing commercial hair treatments.
Care and treatment options
Treatment depends on the cause; no method works for everyone, and some temporary loss improves when the trigger resolves.
When to seek help
Seek assessment if hair loss is worrying or affects emotional wellbeing.
