You can see the difference between 90% and 100%. But if you thin from 100% to 90%, and are not looking at two heads of hair in front of you, you will not notice you've thinned. You will think you were always that way. Other people will just notice you are not as thick as someone else, but will think you are the same you always were. But when you get to 50%, that is when you really know that you are thinning, since you are sure you remember being thicker than that.
When doctors tell you they only need to give you 50% density to look like full density, that simply is not true. The truth is just that if you are thinning, you typically don't notice until you've lost half. Everyone else around you still see that you are thinner than the thick guy over there.
