Miniaturization, What Actually Happens?

Is hair thickness dependent on which phase it is in right now? The hair I shed is much different than the hair I can cut off. It is less pigmented, much thinner, and less robust. I mean MUCH thinner and not just some but all of them. Is this normal? Are hairs in telogen thinner than in the anagen phase?

When a hair miniaturizes, it becomes less thick, losing its mass. It also loses its pigment, becoming white, and it often stops growing. This hair may just hang there for a long time, not contributing to your overall hair mass.
