The Alopecia related to Thyroidism is hair loss related to an imbalance in thyroid hormones, which play a key role in regulating metabolism, including the hair growth cycle.
Both hypothyroidism, low thyroid function, and hyperthyroidism, high thyroid function, can affect hair health and cause hair loss.
It is manifested by diffuse, scalp-wide hair loss; hair may become weaker, drier and prone to breakage; and in auotinmune cases such as Hashimoto's thyroiditis, it may coexist with alopecia aerata, which causes circular areas of hair loss.
