Does semaglutide cause hair loss?

Hair shedding can happen during rapid weight loss (telogen effluvium), regardless of the medication. It’s usually related to calorie reduction, protein intake, stress, or nutrient deficits rather than semaglutide itself. To reduce risk, aim for adequate protein, strength training, and micronutrients. If hair loss is significant, your provider can evaluate labs (iron, thyroid, vitamin D) and adjust your plan.
