How to distinguish miniaturised hairs?

[jonnykino]

Hello!

Just a quick question. How do you distinguish miniaturised hairs from normal hair? I know you lose up to 150 hairs a day. I think I'm within that range. Anyway, I've got blonde straight hair, but I've noticed hairs coming from my head, some being short, thick and brown. Some being long and blonde... but I can't really tell if they're thinner, because they're blonde. I also notice these hairs coming from the back and sides, so I dunno what they are. Any clue?

Thanks!
