Prostaglandin D2 (PGD2) is a signaling molecule discovered at elevated levels in balding scalps. Researchers believe it hinders hair follicles, accelerating androgenic alopecia.
New therapies propose blocking PGD2 receptors or synthesis to keep follicles in a healthier growth state. This approach could be pivotal for older individuals dealing with progressive thinning, complementing standard hormone-based treatments.
