Please check.

Please look up the noun for facial hair above the lip and the last two words in the second sentence.

Why you haven't got moustache and whiskers yet? The hair is not growing because of hormonal imbalance.

Why have you changed "beard" (the right word) to "whiskers" (correct but not natural)?

Look again at the construction of your question, specifically at the subject/verb order.

Jane: Why haven't you got ​a moustache [STRIKE]and[/STRIKE] or a beard yet?
John: [STRIKE]The[/STRIKE] My hair [STRIKE]is not growing[/STRIKE] doesn't grow because of a hormonal imbalance.

See above. I have made it clear (by adding names) that this only works as a dialogue. It wouldn't make sense for the same person to say both sentences.
"Moustache" and "beard" don't have to go together. That's why I changed it to "or". Someone could keep a moustache but shave the rest of the hair off their face (and vice versa).
Note the addition of the articles.

Note that your question would only work in a culture where having a moustache and/or beard is an expectation for boys/men. In many other parts of the world, someone might ask a teenage boy "Are you shaving yet?" The question is designed to find out whether the boy is experiencing facial hair growth yet. Schoolboys here wouldn't go to school with facial hair.

I didn't have facial hair until the age of fourteen.

Does Tim's hormonal imbalance affect only facial hair?

Does Tim's hormonal imbalance affect only facial hair?

No.

Have/haven't you started shaving yet? might be slightly less rude.

If you're very good friends with Tim, he might not mind the intrusive question about why he doesn't have any hair (on his face or anywhere else) yet. However, if you know him that well, you would probably already know that he has a hormonal imbalance.
