**Mounjaro Users Warned: Weight Loss Drug May Pose Unexpected Risk to Hair Health**
The weight-loss medication Mounjaro, recently made available on the NHS for those seeking effective support on their slimming journey, has become a topic of discussion following fresh concerns about its potential side effects. While its appetite-suppressing properties have been widely publicised, new reports suggest some users might be trading more than excess kilos for improved wellbeing.
Dr Donald Grant, a General Practitioner and Senior Clinical Advisor at The Independent Pharmacy, has sounded the alarm over possible hair loss linked to Mounjaro usage. He acknowledges that, although not a universal complaint, notable cases of hair shedding have begun to surface among those on the treatment. “We’re hearing from a number of patients experiencing noticeable hair thinning during their time on Mounjaro,” Dr Grant explained. “Understanding the underlying causes is key to managing and, hopefully, preventing this distressing outcome.”
Rapid weight loss is highlighted as a primary culprit. Dr Grant noted that swift shifts in body mass can cause a type of temporary hair loss known as ‘telogen effluvium’, where hair follicles prematurely enter the resting phase, resulting in increased shedding. This phenomenon is not unique to Mounjaro; it’s seen in various scenarios where dramatic weight reduction occurs.
Nutritional deficits are another factor that could be placing hair at risk. With Mounjaro’s mechanism of action focusing on activating GLP-1 receptors to reduce appetite, users may unknowingly consume fewer nutrients necessary for healthy hair. “A substantial drop in food intake, particularly if meal quality isn’t maintained, can quickly reveal itself in the hair’s condition. Iron, zinc, and vitamins such as biotin are all essential for hair strength and growth,” Dr Grant commented.
Additionally, changes in routine and lifestyle brought about by starting a medical weight-loss journey can increase stress levels—both physically and mentally. “It’s easy to underestimate the impact stress has on bodily functions, including hair growth,” Dr Grant added. “Routine upheavals coupled with emotional and hormonal shifts during rapid weight loss can be just as problematic as dietary shortcomings.”
The good news, according to Dr Grant, is that these issues are not necessarily inevitable and can often be managed with some proactive steps. First and foremost, ensuring nutritional balance remains critical, even as portion sizes decline. “Rather than letting healthy eating habits slip, it’s important for Mounjaro users to prioritise nutrient-dense foods,” the GP advised. Protein-rich foods such as chicken, eggs, and lean red meat, as well as leafy greens, legumes, and nuts, can provide the building blocks necessary for robust hair.
For some, supplements may help bridge the nutritional gap, though Dr Grant cautioned that individual needs can vary, and consulting a healthcare professional before starting any supplement regime is recommended. Iron, protein, zinc, and biotin are frequently cited as nutrients that support hair integrity.
Managing stress is equally important. Dr Grant encouraged users to adopt simple stress-reduction routines, such as regular physical activity, prioritising adequate sleep, and embracing stress-coping techniques like mindfulness or gentle exercise. “Taking care to manage your wellbeing holistically can have positive knock-on effects on both weight loss outcomes and side effects like hair loss,” he suggested.
Finally, Dr Grant urged those experiencing hair loss to treat their hair gently and consider avoiding tight hairstyles, harsh treatments, and excessive heat from straighteners or curlers during weight loss. Keeping a close eye on changes in hair condition and seeking advice if concerns arise is always a prudent step.
For individuals alarmed by unexpected hair thinning, a discussion with a GP is advised. This can help determine whether the medication, diet, or other health issues may be contributing and guide the best course of action to minimise further loss.
As more people turn to pharmaceutical support such as Mounjaro in the battle against obesity, awareness of possible side effects—both cosmetic and medical—remains crucial. While side effects like hair loss may be rare, taking a careful approach to health throughout the process can help ensure a safer and more satisfying journey to better wellbeing.
