March 2014 in “Journal of Investigative Dermatology” This study found that aging mice experience slower and more fragmented hair cycle waves, but transplanting aged skin to a young host can partially restore hair cycling, implicating extracellular factors.
October 2023 in “Scientific reports” In this study, researchers found that the synthetic stress hormone dexamethasone caused opposite effects on hair growth-related proteins, reducing SFRP2 and increasing SFRP3, which respectively stimulate and inhibit hair follicle cell proliferation in human dermal papilla cells.
