A substance called prostaglandin D2 is found more in bald scalps and it stops hair from growing. Blocking its receptor could potentially treat hair loss.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

Prostaglandin D2, found in higher levels in bald scalps, stops hair growth, suggesting that blocking its receptor could potentially treat hair loss.
