2 citations,
January 2004 in “Enshou saisei” Male pattern baldness is caused by certain cells in hair follicles and could potentially be treated by targeting a specific growth factor, TGF-β1.
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.
30 citations,

December 2023 in “Scientific Reports” Scientists created cell lines from balding patients and found that cells from the front of the scalp are more affected by hormones that cause hair loss than those from the back.
1 citations,
