Traumatic Event Kick Started Hair Loss in My 30s?

I am a 32 yr-old male. No one in my immediate family has any signs of baldness. I experienced a traumatic event about 9 mos ago, and have noticed hair loss since, including fast recession/thinning on the front left side. Is it possible for one event to kick start balding which doesn’t stop even long after the event?

You probably have some genetic defect producing hair loss that has skipped generations. Stress is known to kick in the balding process. First, of course, you want to be checked out by a doctor to be sure that there are not medical conditions behind it.
