In women – Imbalance in thyroid hormone is a key cause of sudden hair loss among women. The thyroid gland’s being n the state of overactive and under active might cause hair fall. Thyroid hormones largely influence cellular metabolism of scalp proteins, carbohydrates, lipids and minerals. And the hair matrix cells are highly affected by the thyroid hormones’ excess or deficiency.
