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.

Mice treatments didn't grow hair, a patient treatment may affect immune response, and people with hair loss often feel anxious or depressed.

Alopecia areata is likely an autoimmune disease with unclear triggers, involving various immune cells and molecules, and currently has no cure.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

New targets for making and using brain-synthesized steroids could lead to better treatments for brain disorders and alcoholism.
