Everything You Need To Know About Mounjaro
If you are using Mounjaro and have noticed hair thinning while using it, it is important to note that it is not directly caused by Mounjaro. The cause might probably be because of the amount of time that you’ve lost weight and possible stress that you have encountered. Hair Loss while using mounjaro is typically temporary especially because your body is experiencing a significant weight loss which affects your whole body. Imagine losing significant weight in January then you’ll start to notice hair shedding in the coming months. By the time that your weight is already stabilized later in that year, your hair will now grow back.
Again, it is not directly the Mounjaro that is causing hair loss but the process of losing significant weight alone.
Mounjaro is a prescribed medicine that has an active ingredient called tirzepatide. This is intended for people dealing with Type 2 diabetes and people dealing with chronic weight management. It can be administered at home through self-injected dosages.
Just like any other treatments, Mounjaro also has side effects that might be experienced by people who want to try it. Note that these side effects are only temporary but if these become no longer tolerable, make sure to get in touch with your doctor so you can have immediate medical attention. You might experience nausea, diarrhoea, fatigue, and constipation as you go along with the medication. These side effects may vary from one person to another so make sure to consult with your doctor first to have a realistic expectation.
Does Mounjaro Actually Cause Hair Loss?
While Mounjaro has been shown to cause hair loss in some studies, experts believe that this is largely possible because of the reaction to the physical stress that includes in the treatment itself.
Clinic data suggest that experiencing hair loss is one of the common side effects of Mounjaro with 4 to 6% of patients who have experienced it. However, this side effect is temporary and is expected to grow back as you go along with the medication. Any permanent hair shedding might not be because of taking Mounjaro. If you notice that hair shedding takes more than 6 months in your case, make sure to consult your doctor now so you’ll have a proper knowledge about it.
What Might Be The Connection of Mounjaro to Hair Loss?
Taking Mounjaro itself is not a direct cause of hair loss. However, the outcome of it, which is significant weight loss, plays a huge factor in experiencing it. It might be because of the physical stress that may be because of the treatment. The main reason for hair shedding is called the telogen effluvium. It is the temporary disruption of the cycle of hair growth which is mostly triggered by physical stress when you quickly lose 15 to 20 pounds in a short period of time. Another reason might be the lack of nutrients from the food you take since when you are under the Mounjaro treatment you take less food and it makes you feel instantly full.
Don’t worry because hair shedding is only temporary and your hair will grow back after 6 months from the time you start the treatment.
How Can You Manage Hair Loss While Taking Mounjaro
- Make sure to incorporate food that is rich in nutrients especially with protein, iron, zinc, and B-Vitamins. This is very important to take intentionally since Mounjaro works in reducing your cravings for food so make sure to be mindful of this.
- You can also take other supportive supplements which may help in reducing hair loss. However, make sure to consult with your provider first before doing it to make sure that it won’t affect your body while also taking Mounjaro at the same time.
- Physical hair routines could also help in reducing hair shedding. Make sure to avoid any harsh hair products that could lead to hair loss. You can choose to use gentle hair products that could help in preventing any hair loss and no other reaction to your skin. You might also need to avoid too much heat damage which might be from hair straightener or hair blower.
- If none of the above works, you can also try other medical options such as Minoxidil, PRP, or other hair treatments that might be recommended by a Board-Certified Dermatologist. Make sure to consult with a certified dermatologist to avoid any further hair loss.
- Make sure also to keep a track of your starting weight along with the physical look of your hair so you can have a comparison in the future.
- If hair loss persists for more than 6 months, seek professional help with your chosen clinic to avoid further hair loss or might lead to any more serious condition.

So, The Question is, Is Mounjaro The Direct Cause of Hair Loss?
The answer is No. Mounjaro is not the direct cause of hair loss but the actual result of it is probably the reason. Losing a significant weight within a short period of time might be a huge factor in hair thinning which is due to the physical stress during the whole treatment. Take note that it is only temporary and your hair will eventually grow after 6 months onwards from the time you start taking it.
If hair thinning persists for more than 6 months, make sure to seek help with your chosen clinic so you can properly address your concern.
