Possible mechanisms of miniaturization during androgenetic alopecia or pattern hair loss
September 2001
in “Journal of The American Academy of Dermatology”
TLDR Hair loss occurs due to fewer papillary cells, smaller follicles, and shorter growth phases.
This document explores the mechanisms behind miniaturization during androgenetic alopecia or pattern hair loss, which is caused by a decrease in dermal papilla cells. The paper proposes that a reduction in papillary cell numbers leads to smaller follicles with a reduced duration of anagen. The role of androgens, genetics, and hair follicles are discussed, but more research is needed to fully comprehend these mechanisms. The document also mentions the use of finasteride in treating androgenetic alopecia in men and the prevalence of female pattern hair loss.

FPHL affects hair density and diameter, causing visible hair loss in older women.
research Congenital hypotrichosis due to short anagen
Some children are born with unusually short, fine hair because their hair growth phase is short, but this often gets better by itself during puberty.
