Have something done is a passive form in the English language. "Have something done" can be defined as everything which other people do or provide a service to us. To further clarify the intention of the above see example below:
- I cut my hair
- I have my hair cut
From both these examples, there is a difference of meaning, namely:
If the example of the first sentence is "I cut my hair" contains the sense that my own hair cut without care given by others. In contrast to the second sentence of the second example is "I have my hair cut" contains the sense that someone had cut my hair (meaning someone has to provide services to figure I).
