Ozempic (semaglutide), increasingly used for weight loss, has raised concerns about hair loss among users. Medical experts clarify that the drug itself does not harm hair follicles; rather, the issue stems from telogen effluvium, a condition triggered by rapid weight loss and nutritional stress. Dr. Neha Shah, a Bariatric Surgeon, explains that significant calorie reduction can push hair follicles into a resting phase, leading to increased shedding. A study published in 2025 indicated that nearly 70% of users experienced hair shedding, particularly those losing over 15% of their body weight. Nutritional deficiencies, particularly in protein, iron, zinc, and vitamin B12, exacerbate this issue. Experts recommend maintaining a high protein intake, considering supplements, and consulting specialists to monitor nutritional health. Fortunately, telogen effluvium is usually reversible, with hair growth returning after several months once nutrition stabilizes. However, individuals with genetic predispositions may experience more permanent thinning. Thus, managing weight loss carefully and ensuring adequate nutrition is essential to protect hair health.
