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.

iPSCs show promise for hair regeneration but need more research to improve reliability and effectiveness.

Dermal sheath cells can help grow new hair follicles and show promise in treating hair loss.

Dermal cells are key in controlling hair growth and could potentially be used in hair loss treatments, but more research is needed to improve hair regeneration methods.
