"I cut my hair" and "I had my hair cut" look close, but they describe different events. The first means you held the scissors. The second means you arranged the appointment and somebody else did the work. That second pattern is the causative.
The form is have plus an object plus a past participle: "I had my hair cut." The tense lives in have: I had, I am having, I have had, I will have. The object names the thing or the person that receives the action.
This page explains the form, the difference from the ordinary active sentence, the get alternative and the most common word-order mistakes. The 20-question drill checks each pattern with a short rule.
The rule
The basic form
- The pattern is have plus object plus past participle: "I had my hair cut."
- The subject arranges the action; somebody else performs it.
- The tense is carried by have: I had, I am having, I will have, I have had.
- The object receives the action: my hair, the car, the house, the documents.
Why not say "I cut my hair"?
- "I cut my hair" means you did it yourself.
- "I had my hair cut" means a professional did it for you.
- The causative is common for services: cutting, repairing, cleaning, painting, testing.
- The person who does the work appears with by: "I had my hair cut by a new stylist."
Questions and negatives
- Questions use the normal auxiliary: "Did you have your car repaired?"
- Negatives use do or did with have: "I did not have my watch fixed."
- With a continuous tense, the auxiliary moves: "Are you having your eyes tested?"
- Do not add do when the tense already has one: "Have you had your hair cut?"
The get alternative
- Get takes the same pattern and is more informal: "I got my hair cut."
- Get can also suggest a problem or an accident: "He got his phone stolen."
- Have is neutral and safer in formal writing: "She had the documents checked."
- Choose by meaning: get for incidents, have for planned services.
Common traps
- Use the past participle, not the base verb: "had my car repaired", not "had my car repair".
- Keep the object between have and the participle: "had my hair cut", not "had cut my hair".
- Do not confuse the causative with the present perfect: "I have cut my hair" is not a service.
- With want, the pattern is want plus object plus past participle: "I want this printed."
Examples
- I had my hair cut yesterday.A barber did the work; the speaker arranged it.
- She is having the kitchen painted.The continuous form shows an arranged service in progress.

- She got her nails done for the party.Get is the informal alternative.
- He got his phone stolen on the train.Get can describe an unlucky event.
- Have you had your passport renewed?The present perfect puts have twice: auxiliary and causative.
Common mistakes

- Wrong: I had my car repair. Right: I had my car repaired.
- The causative uses the past participle, not the base verb.
- Wrong: I cut my hair by a barber. Right: I had my hair cut by a barber.
- A service performed by someone else needs have plus object plus past participle.

Questions learners ask
What is the difference between "I cut my hair" and "I had my hair cut"?
The first sentence means you cut it yourself. The second means you paid or arranged for someone else to cut it. The causative adds have plus the past participle, and it moves the focus from the person doing the work to the person receiving the service.
Can I use get instead of have?
Yes, and get is common in conversation: "I got my hair cut." One difference is tone rather than grammar: get is more informal and often describes something that happened to you, especially a problem, as in "he got his wallet stolen". Have is the safer choice for planned services and formal writing.
Does "have something done" always mean a professional service?
Not always. It can describe any action performed for the subject by someone else, including an unpleasant event. "She had her bag stolen" does not involve a service. The shared idea is that the subject did not perform the action; someone or something else did.
