How much hair are you normally supposed to lose in a day?

I've heard up to 100 strands a day is normal...but i would assume it would depend some on the thickness of your hair

How much hair are you normally supposed to lose in a day?

I've lost a lot of hair every time I shower all my life but for me it's normal, I'm not losing my hair. If you've got thick hair it's pretty normal to lose a lot. It could also be simply a vitamin or protien deficiency. Are you losing more than you used to?
