Why Does Miniaturized Hair Shed?

Hi doc, can you explain this answer that you gave to a person that told you that he was shedding lighter and thinner hairs:

“Don’t focus too much on the hair that you lost. In normal periodic hair shedding we may lose both miniaturized and normal hair, since most adult men (50%) experience some degrees of balding at some time.”

So my question to you doc, is why do people shed miniaturized hair???

All hair sheds as it goes through their hair cycle. The “not visible” phase (telogen) lasts about 6 months. The weak hair that is miniaturized is more fragile and falls out with brushing and in those hairs, the hair growth and loss cycle is more active… and the hairs that are miniaturized have a short growth phase (and if they regrow at all, will have a longer telogen phase).
