- How does Setipiprant work on the scalp to potentially promote hair regrowth? Setipiprant blocks the DP2 (CRTH2) receptor that prostaglandin D₂ acts through, and PGD₂ is reported to be elevated in balding scalp — but the one published placebo-controlled trial in men (DuBois 2021, n=169) found no significant hair regrowth. It is an experimental compound, not an approved hair-loss medicine.
