When the Scale Moves Faster Than the Body Can Adapt: Hair Loss in the Age of GLP‑1s
As prescriptions for GLP‑1 weight‑loss medications like Ozempic and Wegovy soar, many patients are noticing an unexpected side effect:
hair loss. Rather than being a direct drug effect, this phenomenon often reflects the body’s response to rapid physiological stress
after significant weight loss. When the body prioritises vital systems, hair follicles enter a resting phase — a condition known as
telogen effluvium — and shedding becomes noticeable months later.
In some cases, rapid weight loss can also reveal underlying genetic predispositions such as androgenetic alopecia. While shedding
is often temporary and may resolve as the body stabilises, persistent thinning or strong family history warrants early evaluation. Proper nutrition,
metabolic adaptation, and professional hair assessment can help protect hair health and inform treatment options.
