Ozempic and Hair Loss: What to Know
Hair loss (telogen effluvium) has been reported by some patients taking Ozempic (semaglutide). This type of hair shedding is typically related to rapid weight loss and nutritional changes rather than a direct effect of semaglutide itself. It is usually temporary and hair growth typically resumes once weight stabilizes and nutrition is optimized.
How Common Is It?
report hair loss while taking Ozempic (semaglutide).
Why Does Ozempic Cause Hair Loss?
- •Rapid weight loss triggers telogen effluvium, a condition where hair follicles shift from the growth phase to the resting phase prematurely
- •Caloric restriction and reduced protein intake can deprive hair follicles of the nutrients needed for healthy growth
- •Deficiencies in iron, zinc, biotin, and other micronutrients from eating less can accelerate hair shedding
- •Physical stress from significant metabolic changes can trigger the body to redirect resources away from hair growth
When Does It Happen?
Hair loss on Ozempic typically begins 2-4 months after starting treatment, coinciding with the period of most rapid weight loss. Shedding may continue for 3-6 months but usually resolves within 6-12 months as weight loss slows and nutritional status improves. New hair growth typically begins before shedding fully stops.
How to Manage Hair Loss on Ozempic
Ensure adequate daily protein intake of at least 60-80 grams to support hair follicle health
Consider a biotin supplement (2,500-5,000 mcg daily) after consulting with your doctor
Take a daily multivitamin with iron, zinc, and vitamin D to address potential nutritional gaps
Avoid harsh hair treatments, tight hairstyles, and excessive heat styling during shedding periods
Talk to your dermatologist if hair loss is significant, as they can check for other contributing factors
Focus on nutrient-dense foods rich in omega-3 fatty acids, such as salmon, walnuts, and flaxseeds
