While you might hear people say "getting your hair did" in casual conversation, especially in some regions, it is considered grammatically incorrect and less formal.
Here's why:
* "Done" is the past participle of the verb "to do," and it's used in this context to mean "styled" or "arranged."
* "Did" is the past tense of the verb "to do." It doesn't make sense grammatically in this phrase.
Examples:
* "I'm getting my hair done for the wedding."
* "She went to the salon to get her hair done."
So, stick with "getting your hair done" for the most grammatically correct and widely accepted way to say it!
