The hair loss you've heard about with GLP-1 medications? It's not the medication doing it.
When your body is losing weight — by any method, whether that's a new eating approach, exercise, or medication — it goes into conservation mode. Hair growth gets deprioritized because your body doesn't classify it as essential for survival. That's true whether you're on a GLP-1 or not. It just so happens that GLP-1 medications are effective enough at producing weight loss that the effect becomes noticeable.
The part that doesn't always make it into the conversation: once weight stabilizes and your body is no longer in a deficit, hair typically starts coming back. It's temporary, not permanent.
If someone you know has been putting off looking into GLP-1 medications because of this, share this with her.
