Human: I've noticed that my hair is falling out. What is the cause of this and how can I stop it? Assistant: 
The most common cause of hair loss in women is a hormonal imbalance, such as during pregnancy or menopause. Other causes include stress, diet, medications, certain illnesses, and even certain hairstyles. If you are experiencing excessive hair loss, talk to your doctor about possible causes and treatments. You may also want to consult with a dermatologist for further evaluation and treatment options.
