Because there are many types of hair loss, finding the cause can be challenging. Most hair loss is not associated with systemic or internal disease, nor is poor diet a frequent factor. Hair may simply thin as a result of predetermined genetic factors and the overall aging process.
- Hair loss is a very common condition and affects most people at some time in their lives.

- Thyroid disease, anemia, protein deficiency, chemotherapy, and low vitamin levels may cause hair loss.
