Ozempic’s Hidden Side Effect: Temporary Hair Loss Concerns Rise Among Users

Weight-loss drugs like Ozempic are making waves, but there’s a lesser-known side effect raising eyebrows: hair loss. Hairstylists across the U.S. are noticing clients with thinning locks while shedding pounds. Ashley DiMatteo, owner of Ashley Lauren Beauty Lounge in Westchester, New York, told WTFNewsRoom that she’s seen a surge in clients dealing with hair thinning or loss, ranging from subtle to dramatic. Her colleague, color specialist Briana Delvecchio, who uses a GLP-1 drug herself, noted clients complaining of drier, thinner hair, likely tied to the stress of rapid weight loss or nutrient deficiencies.

In Ohio, veteran hairstylist Becky Watt echoed the trend, observing excessive shedding during washes but no bald spots. Interestingly, she found that clients who maintain their appetite fare better, suggesting a link to nutrition. Dr. Philip Rabito, a New York City endocrinologist, explained that this phenomenon, known as telogen effluvium, is a temporary stress response triggered by the body perceiving rapid weight loss as starvation. He noted that hair loss peaks within six to nine months but reverses once weight stabilizes and nutrient levels are addressed.

Rabito emphasized that those losing weight quickly, especially with underlying issues like thyroid problems or deficiencies in iron, B12, or vitamin D, are at higher risk. Hairstylists recommend gentler haircare routines—less heat, scalp treatments, and cooler rinses—while urging clients to consult doctors for vitamin checks. Novo Nordisk, the maker of Ozempic, confirmed hair loss as a side effect, noting it’s more common in those losing significant weight (≥20%), with 2.5% of Wegovy users reporting it in trials compared to 1% on placebo.

The good news? It’s temporary. As DiMatteo and Delvecchio reassure clients, with proper care and patience, hair regrows stronger. Rabito even calls it a ‘mark of success’ for weight-loss journeys, as long as nutrient levels are managed. So, while Ozempic may slim waists, it’s also giving scalps a temporary workout.
