Can GLP-1 medications cause hair loss and what can I do about it?

Hair loss, specifically telogen effluvium, has been reported by some GLP-1 users, though it's not a direct side effect of the medication itself. Instead, it's typically related to rapid weight loss and nutritional deficiencies that can occur when calorie intake drops significantly. Telogen effluvium causes increased shedding 2-4 months after a triggering event like rapid weight loss, stress, or nutritional changes.

To minimize hair loss, ensure adequate protein intake (aim for 60-80g daily), maintain sufficient calories for your activity level, and consider a multivitamin with iron, zinc, and B vitamins. Avoid crash dieting and aim for gradual weight loss of 1-2 pounds per week. Most hair loss from telogen effluvium is temporary and resolves within 6-9 months as your body adjusts. If hair loss is severe or persistent, consult your healthcare provider to check for nutritional deficiencies and discuss management strategies.
