The rise of Ozempic as a treatment for type 2 diabetes and weight management has been nothing short of meteoric. Yet, alongside its popularity, a wave of potential concerns have cropped up. First there was “Ozempic face” and now there’s “Ozempic hair”. while on Ozempic, you’re not alone. In this article we explore whether Ozempic actually causes hair loss side effects and what you can do to prevent it. We’ll also review the best treatment options if you’re noticing your hair thinning or falling whilst on Ozempic and other weight loss medicines.
What is Ozempic?
Ozempic is a prescription only injectable medication that contains semaglutide. It was originally licensed for managing type 2 diabetes. In recent years, however, it has exploded in popularity as a weight loss treatment. Semaglutide works by mimicking a natural hormone in the body called GLP-1. This hormone helps regulate blood sugar, slows down how quickly your stomach empties and suppresses appetite. These effects not only improve glucose control but also make it easier to lose weight.
Due to its success, semaglutide is now available in higher doses under the brand name Wegovy which has FDA approval for treatment of obesity. Other similar medications have also since entered the market including tirzepatide which is the active ingredient in Mounjaro and Zepbound. These also target a second hormone called GIP for potentially even more potent weight loss. Oral alternatives like Rybelsus (also semaglutide) are also becoming available. Although originally intended to treat chronic health conditions like diabetes and obesity, many of these medications are now in use off-label for weight loss. As a result, the number of people taking them has exploded and so have the reports of side effects.
Does Ozempic Cause Hair Loss?
First of all, its important to note that hair loss is not an official side effect of Ozempic. At the moment, there is no clinical evidence confirming that Ozempic directly affects hair follicles. However, there are increasing reports from patients and clinicians suggest that some people experience hair shedding, thinning or patchy loss whilst taking Ozempic and other similar weight loss injections. The most likely explanation for this is that these patients are indirectly developing hair loss due to telogen effluvium. This is a temporary disruption to the hair growth cycle. Telogen effluvium commonly occurs due to rapid or significant weight loss which places physiological stress on the body. As a result, hair follicles prematurely enter the resting (telogen) phase, leading to increased shedding typically seen 2–3 months after the stressor. Key triggers for telogen effluvium include:
Another potential cause of hair loss is lower nutrient intake. Ozempic suppresses appetite, which can lead to lower consumption of essential nutrients such as iron, zinc, protein, vitamin D and biotin. All of these vitamins and minerals are necessary for normal hair growth. Deficiencies in any of these may either trigger hair loss. Lastly, there is of course the possibility that Ozempic and similar drugs may cause hair loss through more direct actions. We know that GLP-1 receptors are found all over the body and influence multiple metabolic pathways. As such, there is a possibility that hair follicles may be directly impacted by GLP-1 agonists like Ozempic.
Can You Prevent Hair Falling Out Whilst on Ozempic?
Hair loss linked to Ozempic is not always preventable, particularly if it results from rapid weight loss or nutritional deficiencies. However, there are practical steps that may help reduce the likelihood or severity of hair falling out whilst on Ozempic and similar medications:
- Maintain a Nutrient-Rich Diet: This is crucial even if your appetite is low. Prioritise protein, iron, zinc, vitamin D and biotin to support hair growth.
- Avoid Aggressive Calorie Restriction: Aim for gradual and sustainable weight loss to minimise physiological stress.
- Stay Well-Hydrated: This is because dehydration can negatively affect both hair and scalp health.
- Use Gentle Hair Care Practices: Protect hair from things that can cause break or shedding like heat styling, tight hairstyles and harsh chemical treatments.
- Manage Stress: This can trigger and exacerbate telogen effluvium. Consider mindfulness techniques, therapy or regular physical activity.
What to Do if You Have Hair Loss Whilst on Ozempic
If you’re noticing increased shedding or thinning after starting Ozempic, it’s worth investigating the underlying cause. Hair loss can result from multiple factors, and identifying the right trigger is key to reversing it. Below are practical steps to help you manage hair loss whilst on Ozempic treatment:
- Consult Your Doctor: Start by speaking to your prescribing doctor. Hair loss is often multifactorial and a clinical assessment can help rule out other causes such as thyroid dysfunction, iron deficiency, anaemia or autoimmune conditions like alopecia areata. Your doctor may arrange blood tests to check iron levels, thyroid function and vitamin or mineral deficiencies. The aim is to pinpoint and address the cause(s) of your hair loss. If they suspect that your hair falling out is related to Ozempic they may also adjust your dosage.
- Review Your Nutritional Intake: Ozempic often reduces appetite which can lead to nutritional deficiencies which affects hair growth. Consider consulting a dietitian to ensure your meals are nutrient-dense and balanced. Supplements can help address deficiencies but should only be used under medical supervision to avoid excessive dosing or interactions with other medications.
- Assess the Rate of Weight Loss: Rapid or extreme weight loss is one of the most common triggers for telogen effluvium. If you’re losing more than 1–2 pounds (0.5–1kg) per week, your body may be under stress. This can disrupt the hair growth cycle. Slowing the pace of weight loss where possible can help reduce the risk of further shedding and give your hair a better chance to recover.
- Consider Hair LossTreatments: Targeted treatments can help support regrowth and improve density especially in persistent hair loss. Topical minoxidil, melatonin and caffeine can help support hair regrowth. More advanced interventions like PRP (platelet-rich plasma) therapy and microneedling can also be useful in cases where hair loss is unresponsive to treatment.
Is Ozempic Hair Loss Permanent?
In most cases, hair loss due to Ozempic and other weight loss drugs is not permanent and does not require a separate treatment. Telogen effluvium typically resolves within 3–6 months once you remove the triggering factor. Hair follicles are not permanently damaged, which means regrowth is not only possible but likely. However, in people predisposed to conditions like androgenetic alopecia (pattern hair loss), Ozempic-related shedding could unmask or accelerate this type of hair loss. In these cases, early diagnosis and specific treatment are needed to stop shedding and regrow hair.
Ozempic can be life-changing especially for people with type 2 diabetes or obesity. However, like all medicines, it can have some unwanted results. Whilst hair falling out is not a clinically established side effect of Ozempic, it can occur indirectly as a result if rapid weight loss or nutritional deficencies. If you’re experiencing hair loss on Ozempic or other weight loss drugs, the key is to seek medical help for early diagnosis and treatment. You can also reduce the risks of hair loss by adopting a diet and rate of weight loss that supports hair health.
