At any time roughly 10-15% of your scalp hairs are in the resting (telogen) phase, and these shed at the end of it — about 50-100 a day for most people, sometimes more on wash days when several days' worth come out at once. This is the hair cycle working normally, not hair loss. Long-haired people simply notice it more because each shed hair is more visible.
What's not normal is a sustained, obvious increase — handfuls in the shower for weeks, a visibly thinner ponytail, or a widening part or receding hairline. That points to telogen effluvium (temporary) or pattern loss. If you're worried, count loosely over a few days, take photos, and use a self-check; a dermatologist can confirm with a pull test.

FAQ
How do I know if I'm losing too much hair?
Signs beyond normal shedding include noticeably more hair than usual for weeks, a thinner ponytail, a widening part, or a receding hairline. Diffuse all-over loss suggests telogen effluvium; a defined pattern suggests genetic loss.
Why do I lose more hair on wash days?
Washing dislodges several days' worth of already-shed resting hairs at once, so it looks like more. It's usually normal accumulation, not extra loss caused by shampoo.
