She must have had her hair cut.
Just wanna ask whether the sentence above is grammatically OK. I try to use the causative and the past tense for the modal verbs (“must have done”). I want to express that I am convinced that she used the services of the hairdresser.
Answer
It’s perfectly valid to me.
Her hair looks different. She must have had her hair cut.
