Original sentence
People looks vary a lot: fair or dark, straight haired or curly, short or tall - it takes all sorts to make the world!
Corrected version
People look varies a lot: fair or dark, straight hair or curly, short or tall. It takes all sorts to make the world!
Notes for accuracy
- Use the plural verb that matches the subject: People look (not looks).
- Use look for plural subjects. If you say looks, it sounds like one person. For a group, use look.
- Replace haired with hair when describing hair: straight hair.
- Use a period to end a sentence, or a dash with care. Here, a dash can be replaced with a period or a comma for a softer pause.
- Keep the message positive: the idea that there are many kinds of people is conveyed clearly.
Final tip: You can also write the sentence as two shorter sentences: People look different in many ways. Fair or dark, straight hair or curly, short or tall—there are all sorts of people in the world.
