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.

The document concludes that stem cells and their environments are crucial for skin and hair health and have potential for medical treatments.

The PRP-like cosmetic product with postbiotics effectively treats hair loss in Alopecia areata.
