Does Mounjaro Cause Hair Loss

Yes, Mounjaro can cause hair loss, though it affects fewer than 3% of users according to clinical trials. Hair thinning typically occurs due to rapid weight loss rather than the medication directly damaging hair follicles. When you lose weight quickly, your body may temporarily shift hair growth cycles, leading to increased shedding 2-4 months after starting treatment. Most patients experience regrowth once their weight stabilizes and their body adjusts to the medication. We recommend discussing any concerning hair changes with your healthcare provider, who can evaluate whether the benefits of continued treatment outweigh this temporary side effect.
