The five that work
The correction: "Most people think X. It's actually Y." Shareable, dignified, and the format most likely to be forwarded in a family group. The cost question: "People ask me what this costs. Here's the honest answer." Nobody else answers it, so it stops the scroll on its own.
What I tell my own family: the most trusted sentence a doctor can say, because it signals you are not selling. Who should not have this: counter-intuitive, and it converts because it proves judgement. The unasked question: "Nobody asks me this, but everyone wants to know…"

The five to avoid
"Do you suffer from…" — breaches platform policy on personal attributes and gets ads rejected. Anything that opens on someone's appearance as a problem. Countdown urgency on a clinical decision. "You won't believe what I found" applied to a patient. And any hook promising a result the video cannot deliver, which trains the audience to distrust every future hook you write.
The test is whether the hook survives the video. If someone who watched to the end would feel the opening oversold it, you have borrowed attention you will have to repay.
Write it last, in dialect
Record the explanation first, then listen back and find the sentence you said naturally that is sharpest — that is usually your hook, already in your voice. Writing it first produces something that sounds written, which is exactly the register that gets skipped.
In Arabic, the hook is where dialect matters most. The clinical terms can stay standard, but the opening line should sound like something you would say to a patient across a desk in Salmiya, not a translated headline.
