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.

Different problems with hair stem cell renewal can lead to hair loss.

circRNA-1926 helps goat stem cells turn into hair follicles by affecting miR-148a/b-3p and CDK19.
