    TLDR Levothyroxine overdose can cause hair loss, and zinc deficiency might worsen it.
    The document discussed a case report of an infant with hypothyroidism experiencing diffuse scalp hair loss due to a levothyroxine overdose. The author suggested that, in addition to the overdose, zinc deficiency should be considered as a contributing factor to alopecia in hypothyroid patients. Zinc is crucial for maintaining body homeostasis and is involved in hair growth regulation. The author noted that zinc levels are often altered in individuals with thyroid disease, which could exacerbate hair loss. The association between zinc deficiency and alopecia in hypothyroid patients was rarely reported in the literature at the time.
