Does GLP-1 use cause significant hair loss? What researchers say

Roughly 20 million people in the US, UK and EU take GLP-1 receptor agonists such as tirzepatide and semaglutide, sold under brands like Ozempic and Mounjaro, for weight loss and type 2 diabetes. As use has surged, side-effects are getting more scrutiny, and hair loss has drawn particular attention from researchers. Specialists explain what is known so far about how common the shedding is, why rapid weight loss itself can trigger it, and whether it is a lasting problem.
