April 2023 in “Journal of Investigative Dermatology” Covering a wound can stop hair growth by promoting scarring, but boosting a process called Wnt signaling can help hair grow back even when the wound is covered.
January 2016 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” 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.
October 2012 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” 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.
May 2012 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” Prostaglandin D2, found in higher levels in bald scalps, stops hair growth, suggesting that blocking its receptor could potentially treat hair loss.
