November 1998 in “The journal of investigative dermatology/Journal of investigative dermatology” Beard cells, unlike scalp cells, produce growth factors in response to testosterone, which may explain differences in hair growth.
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.
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.
6 citations
,
January 2022 in “Journal of Investigative Dermatology” Male pattern baldness is linked to higher levels of a certain receptor in the scalp, which leads to the shrinking of blood vessels and hair loss. Early treatment targeting this receptor could be more effective.
1 citations
,
