Is Jotaro's hat his hair?

Excuse me, but could you possibly clarify something for me? The question, "Is Jotaro's hat his hair?" seems to be quite an unusual one. Are we referring to Jotaro Kujo from the popular manga and anime series "Jojo's Bizarre Adventure"? And if so, are we discussing the physical characteristics of his attire, specifically the hat he often wears? Because as far as I'm aware, a hat is an accessory worn on the head, separate from one's hair, so it would seem a bit of a stretch to suggest that they are one and the same. Could you perhaps elaborate on the context or intent behind this question?
