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.

People with hair loss have different hormone levels, and these hormones can affect hair growth.

Male hormones, particularly DHT, are linked to male pattern hair loss, and treatments like finasteride can help, but they don't work for postmenopausal women's hair loss, which may have different causes.

Minoxidil, a common hair loss treatment, might work by counteracting a hormone that reduces hair growth and promotes hair loss.

Hypertrichosis lanuginosa causes excessive fine hair growth, often linked to genetics or cancer, with limited treatment options.
