Ozempic has revolutionized weight loss and diabetes control, but with every passing day new evidence indicating to its impact on health needs closer examination. Although the new research doesn't necessarily establish that semaglutide is responsible for vision loss, it raises enough red flags to prompt further research and careful surveillance by patients and clinicians alike. As studies continue, individuals using these medications should remain aware of potential risks and take proactive steps to protect their vision. In 2023 alone, nearly 2% of the U.S. population was prescribed semaglutide, reflecting its widespread acceptance as an effective treatment.
But while shedding pounds is the goal, some users are facing an unexpected side effect—hair loss. Imagine going in the shower one day to catch clumps of hair in your hands. Shaky stuff, right? Hundreds of people who are taking the semaglutide drugs, such as Ozempic, are finding their hair doing the same, creating concern over what is actually happening in the body. Is the drug, or is extreme weight loss too soon the culprit?
When Desiree Rodriguez started taking a semaglutide drug to aid her weight loss journey, she expected the pounds to drop—not her hair. But around the 20-pound mark, she noticed something alarming: clumps of hair coming out in the shower, filling her hands with strands she never expected to lose.
If you're on a weight loss journey, you need to listen," she cautioned in a TikTok video that went viral. "You absolutely need to be eating right and taking vitamins.
Rodriguez is not isolated. Numerous people who use semaglutide-based drugs such as Ozempic and Wegovy have also reported excessive hair loss, a symptom that has become the subject of active online debate. Even the U.S. Food and Drug Administration (FDA) has monitored more than two dozen reports of hair changes among patients who use semaglutide. But why is this happening, and more crucially, can it be avoided?
Though one might initially suspect the drug itself, experts say the actual culprit is weight loss. Telogen effluvium—a temporary condition of hair loss associated with physical or emotional stress—is a typical outcome of substantial weight loss, such as that caused by semaglutide medications.
Hair experiences a natural cycle of rest, growth, and shedding. But when the body is subjected to severe stress—like a sudden drop in calorie intake—it takes priority for vital functions over hair production. This change pushes a significant number of hair follicles into the resting phase, resulting in excessive shedding some three months later after the stressor.
Dr. Rocio Salas-Whalen, a New York endocrinologist, clarified on TikTok, "For healthy hair growth, sufficient caloric intake should occur. When patients are put on stringent calorie-restrictive diets, this will affect their hair growth."
Semaglutide acts to replicate the action of the GLP-1 hormone, a hormone that influences appetite and eating. While effective in weight reduction, it decreases hunger dramatically in some cases to the extent of not taking adequate necessary nutrients.
Protein, zinc, iron, vitamin D, and B-complex vitamins are all essential for promoting healthy hair growth. Deficiency in any one of these nutrients can worsen hair thinning and slow regrowth. Most patients on GLP-1 medication do not obtain their daily nutritional requirements, experts say, which leads to over-shedding.
For Rodriguez, the answer boiled down to two simple modifications: boosting her protein consumption and adding focused supplements to her daily plan.
Protein is among the most significant nutrients for having healthy and strong hair. Hair is composed mostly of keratin, a protein that needs proper dietary intake to be synthesized effectively. Studies indicate that eating at least 100 grams of protein every day can help prevent hair loss due to quick weight loss.
Rodriguez felt the difference when she made a conscious decision to add more protein-rich foods to her diet. "Once I began adding 100+ grams of protein a day, I noticed the shedding slow down," she posted on TikTok.
For individuals taking semaglutide, adding lean meats, eggs, Greek yogurt, legumes, and plant-based proteins to their diets can maintain hair growth while they continue their weight loss regimen.
In addition to supporting her hair's overall health, Rodriguez started taking Mary Ruth's Liquid Morning Multivitamin and using Minoxidil, which is a topical solution renowned for inducing hair growth.
Experts suggest certain vitamins and minerals that have been known to make hair stronger and lesser to shed, such as:
If on Ozempic or comparable meds, a high-quality multivitamin will supply nutrients that may have been stripped and help avoid loss of hair.
Although troubling, hair loss caused by Ozempic and other medications is fairly rare. During clinical trials involving Wegovy, a side effect experienced by only 3% of adults was hair loss, compared to 1% taking the placebo. In one study of tirzepatide (a weight loss medication marketed as Mounjaro), 5.7% of patients reported hair loss.
In comparison, 57% of patients who have bariatric surgery have severe hair shedding. Although these statistics indicate that hair loss is a potential outcome with semaglutide, it is by no means certain.
If you're experiencing excessive shedding on semaglutide, there are a number of things you can do to slow or even reverse the process:
The silver lining: Hair loss due to quick weight loss is often temporary. Most people notice regrowth after six months to a year as their body adapts to its new weight.
