Injectable therapies for pattern hair loss were found to possibly improve density, with dutasteride prominent, though evidence was judged too heterogeneous for routine use. Dietary supplements for pattern hair loss were found to improve density versus placebo in a network meta-analysis, including Nutrafol, pumpkin seed oil and tocotrienols. Bacillus fermentation products enhanced minoxidil skin penetration and regrowth in mice. An adenosine cocrystal delivery system promoted follicle growth in preclinical tests. Autologous γδ regulatory T cells restored follicle immune privilege and regrowth in human alopecia areata skin models.
