Most people use Mounjaro (tirzepatide) to lose weight, look good and feel their best. So, if you\u2019ve heard reports that Mounjaro causes hair loss, it\u2019s natural to be concerned.<\/p>\n\n\n\n

Like any medication, Mounjaro comes with potential side effects<\/a>. That\u2019s why your healthcare provider will lay out the risks and benefits before prescribing it. So is hair loss one of them?<\/p>\n\n\n\n

Below, we explore the link between Mounjaro injections<\/a> and hair loss. Plus, you\u2019ll get tips on how to prevent and manage it while staying on track with your weight loss.<\/p>\n\n\n\n

Does Mounjaro Cause Hair Loss?<\/h2>\n\n\n\n

Yes, some patients experience hair loss during treatment. It is listed as a common side effect in the patient information leaflet<\/a>. This is supported by clinical trial data.<\/p>\n\n\n\n

Results from clinical trials suggest only a small percentage of patients will notice hair loss. Around 4% to 5% of Mounjaro and other weight loss medication users reported hair loss to some degree<\/a>.<\/p>\n\n\n\n

However, experts believe it\u2019s not necessarily the drug itself that causes hair loss<\/strong>. Instead, weight loss on Mounjaro could trigger a condition known as telogen effluvium<\/strong><\/a>.<\/p>\n\n\n\n

Telogen effluvium happens when sudden changes in the body cause hair follicles to enter the resting phase and shedding phase of the hair growth cycle. This leads to increased hair loss, which is often temporary.<\/p>\n\n\n\n

Rapid weight reduction is a common trigger for telogen effluvium, as it can put the body under stress. Other triggers include illness, malnutrition, high stress and childbirth.<\/p>\n\n\n\n

Why Am I Experiencing Hair Loss on Mounjaro?<\/h2>\n\n\n\n

Mounjaro itself does not directly<\/em> cause hair loss. Rather, it is significant weight loss associated with Mounjaro that can cause telogen effluvium. This can lead to hair loss.<\/p>\n\n\n\n

When you lose a lot of weight over a short period of time, the body can also prioritise more important bodily functions, like organ function, metabolism, and immunity. The body doesn\u2019t view hair growth as a vital function in the short-term. As a result, hair growth may stop or slow down. This can indicate that you’re losing weight too quickly.<\/p>\n\n\n\n

Several other factors may contribute to hair loss<\/strong> during treatment with Mounjaro, including:<\/p>\n\n\n\n
