SULT1A1 biomarkers for minoxidil may predict responders and enable personalized dosing. Topical finasteride in postmenopausal women improved hair density and thickness. Sodium citrate in growth-factor injections cut pain and improved density versus alternatives. Finasteride tapering after sexual side effects reportedly let men continue treatment, per its retrospective title. GLP-1 agonists and hair loss appear mostly transient telogen effluvium from rapid weight loss rather than drug toxicity, though paradoxical improvements are also reported. Laser-assisted growth-factor delivery raised density roughly 23–26% versus 5% with laser alone. PRP versus growth factor concentrate both helped, with evidence too heterogeneous to rank. Upadacitinib in adolescent alopecia areata ranked above baricitinib and ritlecitinib.
