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.

Stem cell therapy shows promise for treating hair loss in androgenetic alopecia.

Immune cells are essential for early hair and skin development and healing.

Chemotherapy often causes hair loss in cancer patients, affecting their mental health, but scalp cooling can help prevent it.
