She uses it in negative: I didn't have a head for chemistry.

Are these okay?

1. Amita has a head for English. He's learned the language in less than six months and he's quite fluent.

2. She has a head for numbers. She always passes her math exams with flying colors.

3. Laura has a head for detecting lies. Always be honest with her.

4. Jane doesn't have a head for biology. She always fails it miserably.

5. She has a head for business and finance. She's been running three successful start-ups.

I don't know how how commonly it's used, but if you say "Jack has a head for business" people will know what you mean.
