February 2026 in “Nature Communications” Inhibiting connective tissue sheath contraction may improve hair growth in male pattern baldness.
January 2026 in “Open MIND” A recent study explores a non-androgen pathway for treating androgenetic alopecia (AGA) by targeting the PIEZO1 and MLCK axis, which is implicated in follicular miniaturization due to connective tissue sheath hypercontractility. The research screened a library of 2,529 natural compounds using advanced computational methods to identify candidates that could potentially inhibit this pathway, with promising bioavailability for topical application. However, these findings are purely computational and require further *in vitro* validation, with no current clinical claims or products available.
