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.

Blocking the CCR5 receptor may be a new way to treat hair loss from alopecia areata.

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.
