Why hair falls out
Pattern loss is the most common cause but far from the only one, and the timing is the clue. These guides sort the causes with evidence: what is inherited, what is a shedding episode after a shock, what is a scalp problem, what is a style that pulls, and what is a myth.
Try it
Shedding everywhere and pattern loss in zones look different. The shedding calculator covers the first; the Norwood scale checker covers the second.
Heads up
Hair loss that began within months of starting a new medication is a this-week dermatologist visit. Do not stop the medication on your own; ask the prescriber.
