| Increased shedding | Visible hair loss |
|---|---|
| More fallen hairs than usual | Changing outline, bald area or reduced density |
| Can follow stressors or illness | Can have hereditary, immune, inflammatory or other causes |
| May be temporary | May continue unless the cause changes or is treated |
| Hair count is the main observation | Scalp appearance is the main observation |
Why hair counts are difficult
Normal shedding varies and people rarely count consistently. Shower frequency, hair length and brushing habits change how much hair appears at one time.
Why photos still help
Standardized images can document whether visible density or the hairline changes while shedding is happening. They cannot establish why it is happening.
Do not stop medication on your own
If you suspect a medicine or treatment is involved, speak with the prescribing clinician rather than stopping it abruptly. [source]
