Came back, as hair

GREWIN

Think of what happens when you let your hair return to its natural state after cutting or shaving it over time. The answer is a past tense verb that starts with "G."

The clue plays on the phrase "came back," which can mean both returning and hair regrowth. "Grew in" is a common way to describe hair that has returned after being cut or lost, making it a clever double meaning. The answer fits because it literally means hair that has grown back in place.
