March 2014 in “Experimental Dermatology” Leptin helps start the growth phase of hair.
May 2025 in “Texas Digital Library (University of Texas)” In this study, researchers using Arabidopsis thaliana found that adenosine may inhibit root hair growth and stomatal opening, suggesting it plays a signaling role in plants similar to its function in animal cells, potentially revealing a new adenosine-like receptor pathway.

January 2010 in “The FASEB Journal” This study found that prolactin is a key regulator of keratin expression in human hair follicles, enhancing specific keratin types and influencing epithelial stem cell-associated keratins.
August 2026 in “Cell Communication and Signaling” This study found that intravenous administration of a shark-derived receptor antibody, 3P17, promoted hair growth in mice by increasing hair matrix cell proliferation and activating leptin-STAT3 signaling, with transdermal leptin delivery enhancing this effect through improved skin penetration.
