Therapy for Alopecia Areata in Mice Using Parathyroid Hormone Agonists and Antagonists, Linked to a Collagen-Binding Domain

Alopecia areata is an autoimmune disease causing patchy hair loss, often with other autoimmune disorders, but its exact causes are unknown.

Alopecia areata can sometimes appear as a straight line of hair loss instead of round patches.

Combining platelet-rich plasma therapy with prostaglandin-F eye drops can significantly regrow hair in alopecia universalis.

Future hair loss treatments should aim to extend hair growth, reactivate resting follicles, reverse shrinkage, and possibly create new follicles, with gene therapy showing promise.
