What is the relationship between insulin resistance and hair loss?
Stress and/or diseases which are out of balance may increase hair loss. An interesting relationship between high insulin levels is discussed at PubMed — Hormones and hair patterning in men: a role for insulin-like growth factor 1?. This raises an interesting issue that may or may not make sense: Would dropping sugar levels, which will reduce insulin in the blood stream, reduce or stop hair loss?
