1 citations
,
May 2017 in “InTech eBooks” Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
6 citations
,
January 2022 in “Journal of Investigative Dermatology” Male pattern baldness is linked to higher levels of a certain receptor in the scalp, which leads to the shrinking of blood vessels and hair loss. Early treatment targeting this receptor could be more effective.
