The 3-second rule: how to write a hook that stops the scroll
Most videos are judged before the first sentence ends. Here is how to earn the next ten seconds.
Most videos are judged before the first sentence ends. On TikTok and Reels you have about three seconds to give a viewer a reason to stay, so the hook is not a nice extra. It is the video.
Start with the problem or the payoff
The strongest hooks do one of two things: they name a problem the viewer already feels, or they show the result they want. A line like "I stopped using five serums for this one" works because it makes a bold claim and invites a question.
Make it specific
Replace general words with concrete details such as numbers, names and time frames. "Lost 3 kilos in 6 weeks" beats "got fit", and "in my kitchen at 6am" beats "at home".
A simple formula
Callout: speak to who the video is for.
Tension: say what is wrong or surprising.
Promise: hint at what they get by staying.
Test before you commit
Never trust a single hook. Write several, shoot them cheaply and let the numbers decide. A weak hook on a great video loses to a strong hook on an average one.
