I cut my hair yesterday. (I cut it myself)
I had my hair cut yesterday. (I went to the hairdresser)
We also use causative have when someone does something to us.

Important points
Get is possible instead of have, usually in informal spoken English.I'm going to get my car fixed tomorrow.
We can also use have someone do something to talk about giving instructions or orders which is more common in American English.
I had my assistant type the report.
I'll have my lawyer look into it.

Teaching causative

I give a few examples of my own:
I'd have my nails done once a week.
I'd have my garden weeded and my lawn mowed.
I'd have my bedroom redecorated in beautiful oriental sumptuous colours and fabrics.
I'd have the evening meal cooked by a professional cook.
I'd have my shopping done and the house cleaned from top to bottom every two days.
This would leave me time to do the things I enjoy, like reading, chatting to friends, going for walks and playing tennis."

1. Elicit the FORM from the students (have/has + noun + past participle)
2. Use the following concept questions to elicit YES or NO:
Do I cut my hair? Ss: NO
Does somebody else cut my hair? Ss: YES
Do I pay money? Ss: YES
3. If you cut your hair yourselves, how would you say that? I elicit: I cut my hair.
4. Elicit that every week expresses "a habit", and have is in the present simple tense
5. Write the following on the board: house/clean and elicit I have my house cleaned
Of course I repeat the concept questions to make sure that my students grasp the new structure, and I have them drill it (whole class/individuals).
6. Written practice.
Good luck.

My computer is not working, I need to get it fixed.
I ask my students to go out of my classroom with me and pretend that they are school inspectors. The students are asked to mention all the problems they see in the school. They find out problems in teams like:
The pool is dirty, the steps are chipped, the handrail is scratched.
When we go back to the classroom, they must give a solution to all the problems they saw or identified. We all check the answers and correct them as a group. As a follow-up activity, I ask them to check the problems they see in their house and give solutions for homework.
I hope you like this idea. This is a real effective communicative activity."
Prof. German Albavera

Students work on the importance of working as a team inside the family so the house and errands are done on time. They comment about how friends help each other in good and bad moments. They make posters with lists of things the get/have done by others. They choose which favour was the most memorable."

"3 people have had money stolen from their offices"
This looks like causative but uses "have" + "had". Anybody know how to teach this use?"

Then you can elicit a few modal sentences from one of the students, put it on the board and clarify the form and meaning.
In changing it into the active it can be quite funny, as you can't really take our own wisdom teeth out. You can even bring in some gory pictures! :)

"I had my car fixed". Then ask: a.)did I fix it? Students answer "No" b.)did the mechanic fix it? Students answer "yes" c.)did I pay for it? They answer "yes". Finally I write on the board the form of causative.
