Does Hair Miniaturize While It is Growing?

Question about ministurization. Can hair miniturize throughout growth or does it only miniturize after previous hair has fallen out. The hair that I lose I find some of them are really thick while some of them are thick but are thin near the root – is this miniturization? Thanks

Balding men lose mostly miniaturized (thinner) hairs, but they do lose normal thickness hairs. I believe it happens within the anagen (growth) phase and during the telogen (rest) phase of the hair cycle, but things are not always clear cut. Some hairs are partially miniaturized and can look thick, and the hairs you are looking at in a point in time may not be found again when looking anew. Usually the hair follicle that stops producing hairs will make the root of the hairs shrink and eventually the shaft of the hairs would also shrink (in a continuum).
