The findings reach mice, none yet in people. 1 lab.
None of its findings points the other way.
Studies of skin macrophage depletion measured 2 outcomes; the most studied are melanocyte-lineage protein expression (1 study) and hair follicle transition from telogen to anagen (1).

Experiments in male mice aged 18–24 months linked a protein from skin fat to immune cell buildup and delayed entry into the hair-growth phase.Experiments in male mice aged 18–24 months linked a protein from skin fat to immune cell buildup and delayed entry into the hair-growth phase.
