From your pictures, it looks more like your hair is weighed down than thinning. But it's really hard to tell.

Do you wash and style daily? If you counted 100 hairs in the drain and you wash every other day, that's at the low end of normal for hair loss. Also if you're growing your hair out, the wad of hair in the shower drain after you wash will be larger because the hairs are longer.

Have you noticed any patchy spots on your scalp? Unfortunately no one on this site is qualified to give you advice if your hair is really falling out for some medical reason.

One more thing you might want to look into is traction alopecia. If you wear your hair pulled back severely, like in a tight ponytail or headband, you could experience hair loss. You can also lose hair if you part your hair exactly the same way every day.
Sort of CG sometimes, but not really
2B, medium? normal porosity and elasticity?
