* Clauses require a subject and a verb. This phrase only has a subject ("the haircut").
* It's a dependent clause fragment. To be complete, it needs to be joined to an independent clause.
Example:
* Incorrect: That the haircut made.
* Correct: *She was thrilled that the haircut made her feel confident.*
Here, "that the haircut made her feel confident" is now a dependent clause functioning as the object of the verb "was thrilled".
