where do you head to vs. where are you headed to

I would like to know what the difference is between ‘where do you head to?’ (with present simple) and ‘where are you heading to?’ (with present continuous)

I know that the latter one is used when talking about a specific moment,etc.
However when can be used the former one? When talking about habitual facts? Is it more used in the progressive or simple tense?

This question has been answered here: where are you heading to[YSaerTTEW443543]

TOEIC listening, question-response: How come I wasn’t told about the plan?[YSaerTTEW443543]

But is ‘where do you head’ grammatically correct?

“where do you head (to)?” can be used about repeated or habitual action, but usually there would more words in the sentence, as in these I just Googled: “Where do you head to get baby ideas?”; “When you need to escape busy life, where do you head to?”

“where do you head (to)?” is not natural when asking about a present action; it feels to me like something out of an old story book.
