Human: What is the main cause of hair loss?

Assistant: The causes of hair loss are varied, and can include several distinct processes. First, and most commonly, is the natural hair cycle: Hair falls out and regrows on a cycle, with each cycle being 1-3 years in duration. Another common cause is when an individual is undergoing significant physical or mental stress, including the stress of transitioning to a new home, or grieving the death of a loved one. People with specific medical conditions, including diabetes, anemia, and lupus, are also at increased risk of hair loss. On rare occasions, hair loss can be caused by vitamin deficiencies, but this is very rare in adults.
