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.

In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

SOX9 helps determine stem cell roles by interacting with DNA and proteins that control gene activity.
