    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 authors suggested a causal link between alopecia and levothyroxine therapy, but it was proposed that zinc deficiency should also be considered as a contributing factor. Zinc is crucial for maintaining body homeostasis and is involved in hair growth regulation. Hypothyroid patients often have altered zinc levels, which could exacerbate hair loss. The document highlighted the need to consider zinc deficiency in similar cases, as this association was rarely reported.
