If people lose hair every day, why do they still have so many?

Question

So, if people lose about 50-100 hairs a day how is there still so much? especially with people who have really long hair where it would take a long time to re-grow. I understand that people have roughly 100,000 hairs on a head but if it’s almost every day for years, how does stay unnoticed?

Answer 1

You’re misunderstanding what happens there. Yes, 50-100 hairs are lost every day, but they’re almost immediately replaced with new hairs. Those hairs will themselves grow until they fall out in turn. The combination of how fast the hair falls out and how fast it grows determines how long it will get.

Obviously it *is* possible to lose more hair than is replaced, that’s why hair thinning and baldness happens, but that tends to happen more as we age, especially for men.
