Learn English – “Why the sun shines?”

grammaticalityquestionssentencesyntactic-analysis

I've seen questions framed in the following manner many a time:

"Why the sun shines?"
"Why hair grows?"

While the most correct way to frame these kind of questions is obviously:

"Why does the sun shine?"
"Why does hair grow?"

I was wondering if the former two sentences are grammatically sound. They are not something I would personally say, and it doesn't sound right to me (I've always thought they're wrong); but is it wrong to frame questions in that manner?

Clauses beginning with Why are often used as headings to articles that answer the implied question, but the use of a question mark in such cases is inappropriate and misleading.
