Does Semaglutide Cause Hair Loss?
Hair loss is listed as a possible side effect of semaglutide in prescribing information. Clinical trials reported hair loss in a small percentage of users. The exact rate is low, but it is recognized by regulators and doctors.
Why Hair Loss May Happen
Semaglutide can lead to weight loss and reduced calorie intake. Sudden changes in nutrition and body stress may push hair follicles into a resting phase. This temporary shedding is called telogen effluvium and usually improves over time.
What to Do If You Notice Hair Loss
Talk with your prescribing clinician before stopping semaglutide. They can check for other causes, such as thyroid issues or nutrient deficiencies. A balanced diet with enough protein, iron, and zinc may support hair regrowth.
